1. This experiment was to find how mass and speed effect KE. This is important because if you were in a situation where you needed something to go higher, you would know to add more or less of mass/speed.
To test mass, we filled the bean bag with a certain amount of water, then dropped it. After, you recorded how high it made the bean bag go. The same with speed, but same amount in the bottle, just dropped from different heights.
My hypothesis is when you have more mass, the KE will be greater. This is also the same with speed, if it is dropped from a higher place, the bean bag will launch farther than the last time.
2. Data I collected from the lab was like my hypothesis explained. When the height of the bottle increased, it made the bean bag go higher than the last. And I tested 4 different masses, 0.125 kg, 0.250kg, 0.375kg and 0.500kg. Each time the bean bag went higher on a larger mass.
A lot of times on the speed test, the bean bag would go higher than the bottle drop point, but not every time. Also, when it was dropped from the same height each time, some results varied quite a bit, like when it was dropped from 1.28 the results were 1.14 then 1.30 1.30. Mass on the other hand was all in the same number range, only once the numbers were a bit off from each other.
3. Some formulas I used were KE= ½ mv^2 and Ht v^2/2g. The first was to calculate the kinetic energy of an object, m=mass v=speed. Second was for finding out what height I needed to drop something to reach a certain speed, Ht=Height and g= Gravitational Acceleration of 9.8 m/s^2.
I used these to figure out tables that showed relationships between different things like mass and KE or speed and height. The whole time I was doing the lab, my data was going up, when there was more mass/speed there were higher values in the table.
This means that my hypothesis at the beginning was correct, more of m/s means KE will increase proportionally because they are all linear. I found it surprising when the bean bag height went over the water bottle drop mark.
4. To conclude, my hypothesis matched my data. The data values went up when more mass or speed was added. This means if I were in a situation where I needed more kinetic energy for something, I would know to increase mass or the speed of the object giving it energy.
The reason that this hypothesis is correct is when you have more mass, you have more energy. So, when you drop let's say a baseball, it isn’t that heavy so it would only launch the bean bag so far. But a bowling ball is very heavy and has lots of energy when falling because of that, it would make the bean bag go very high.
To make this experiment better, I would use a smoother material for the lever so energy wouldn’t be lost by friction from wood rubbing together. Also, maybe a scanner or video camera to more accurately record how far the bean bag went. All of these would help the lab get more precise results, maybe they could be used in a future lab.

What is the difference in drawing Lewis Dot
Structures for ionic and covalent bonds?
The Lewis Dot Structure for ionic compounds must demonstrate how the electrons are transported to create the ions in the compound. The Lewis Dot Structures of covalent compounds must demonstrate how the electrons are being shared to finish the octets of each atom in the molecule.
What is an ionic compound ?A chemical compound known as an ionic compound is one that contains ions bound together by the electrostatic forces known as ionic bonding. Despite having both positively and negatively charged ions, or cations and anions, the molecule is generally neutral.
The term "ionic bonding" refers to a bond in which the ionic character is greater than the covalent character, i.e., when there is a significant difference in the electronegativity of the two atoms, which makes the bond more polar (ionic) than in a covalent bond, where the electrons are distributed more evenly.
The Lewis structures are not frequently drawn for ionic compounds due to the electrical motion of electrons.
Thus, The Lewis Dot Structure for ionic compounds must demonstrate how the electrons are transported to create the ions in the compound.

as a change of state takes place, heat and temperature
a. increase stays the same
b. stays the same, stays the same
c.stays the same, changes.
d.increases,increases
Answer:
c. stays the same, changes
Explanation:
temperature and heat go hand in hand, however while the change of state occurs, the temperature remains the same while the heat increases since the heat input is constant.
As a change of state takes place, heat and temperature: C. stays the same, changes.
Matter can be defined as anything that has mass and occupies space. Thus, any physical object or substance that is found on earth is typically composed of matter.
Since all matter are made up of atoms, they have a property of existing in three (3) distinct states and these include;
Solid.Gas.Liquid.Generally, matter changes state when heat (thermal energy) is released or absorbed with a corresponding change in its temperature.
In conclusion, at the point when the change of state is taking place, heat stays the same and temperature changes.

The reaction below shows how the potential energy changes during a
chemical reaction. What does the red arrow show?
Answer:
Option C. Change in enthalphy is negative, the reaction is exothermic.
Explanation:
In the profile diagram given in the question above, we can see clearly that the energy of the reactant (Hr) is higher than the energy of product (Hp).
Hence, the enthalpy change (ΔH) will be negative i.e
Enthalpy change (ΔH) = Energy of product (Hp) – Energy of reactant (Hr)
ΔH = Hp – Hr = negative (–) [since Hr is higher than Hp]
A reaction in which the enthalpy change (ΔH) is negative is termed exothermic reaction.

How much heat, in kilojoules, must be added to a 580 g aluminum pan to raise its temperature from 25∘C to 150∘C?
---The specific heat capacity for aluminum is 0.897 J/g∘C.
---Round the answer to two significant figures.
Answer:
Q = 65 kJ
Explanation:
Given that,
Mass, m = 580 g
Initial temperature, [tex]T_i=25^{\circ} C[/tex]
Final temperature, [tex]T_f=150^{\circ} C[/tex]
The specific heat capacity for aluminum is 0.897 J/g°C
We need to find the heat added to the aluminium pan so that its heat raised to a temperature from 25°C to 150°C. It is given by :
[tex]Q=mc\Delta T\\\\Q=580\ g\times 0.897\ J/g^{\circ} C\times (150-25)^{\circ} C\\\\Q=65032.5\ J[/tex]
or
Q = 65.03 kJ
or
Q = 65 kJ
Hence, the heat added to the pan is 65 kJ.
A student titrates 0.1719 g of an unknown monoprotic acid to the equivalence point with 21.85 mL of 0.1062 M NaOH. Which of the following is most likely to be the unknown acid? propionic acid (MM 74.08 g/mol) nitrous acid (MM 47.01 g/mol) chlorous acid (MM 68.46 g/mol) benzoic acid (MM 122.12 g/mol) lactic acid (MM: 90,08 gimol)
Answer:
Propionic acid
Explanation:
Step 1: Write the generic neutralization reaction
HA + NaOH ⇒ NaA + H₂O
Step 2: Calculate the reacting moles of NaOH
21.85 mL of 0.1062 M NaOH react.
0.02185 L × (0.1062 mol/L) = 2.320 × 10⁻³ mol
Step 3: Calculate the reacting moles of HA
The molar ratio of HA to NaOH is 1:1. The moles of HA are 1/1 × 2.320 × 10⁻³ mol = 2.320 × 10⁻³ mol.
Step 4: Calculate the molar mass of HA
0.1719 g of HA correspond to 2.320 × 10⁻³ moles.
MM = 0.1719 g/2.320 × 10⁻³ mol = 74.09 g/mol
With this molar mass, the most likely acid is propionic acid.

within a balloon there are 3 types of gases. the first gas, A, is 6.0 grams in amount, the second gas, B, is 4.0 grams and the last, C, is 3.5 grams. The molar mass of gas "A" is 13.56 g/mol, "B" is 11.76 g/mol and "C" is 12.07 g/mol. If the total pressure inside the balloon is 15 atm, what is the partial pressure of each gas?
Answer:
Partial pressure of Gas A = 3.91 atm
Partial pressure of Gas B = 5.10 atm
Partial pressure of Gas C = 5.99 atm
Explanation:
Number of moles of gas A;
n_A = 13.56 g/mol ÷ 6 g = 2.25 moles
Number of moles of gas B;
n_B = 11.76 g/mol ÷ 4 g
n_B = 2.94 moles
Number of moles of gas C;
n_C = 12.07 g/mole ÷ 3.5 moles
n_C = 3.45 moles
Total number of moles = n_A + n_B + n_C = 2.25 + 2.94 + 3.45 = 8.64 moles
Mole fraction of gas A; X_a = 2.25/8.64
Mole fraction of gas B;X_b = 2.94/8.64
Mole fraction of gas C;X_c = 3.45/8.64
Now, partial pressure of each gas will be;
Mole fraction × Total pressure
We are given total pressure of 15 atm.
Thus;
P_a = (2.25/8.64) × 15
P_a = 3.91 atm
P_b = (2.94/8.64) × 15
P_b = 5.10 atm
P_c = (3.45/8.64) × 15
P_c = 5.99 atm
Thus;
Partial pressure of Gas A = 3.91 atm
Partial pressure of Gas B = 5.10 atm
Partial pressure of Gas C = 5.99 atm

radium 226 has a half life of 1600 yers. suppose we have a 300g sample. how much remains after 200 years
Answer:
[tex]A=275.1g[/tex]
Explanation:
Hello.
In this case, since the radioactive decay is computed via:
[tex]A=A_0*2^{-\frac{t}{t_{1/2}}[/tex]
For the initial amount of Ra-226 (300 g), once 200 years have passed, the remaining mass is:
[tex]A=300g*2^{-\frac{200years}{1600years}}\\\\A=275.1g[/tex]
This is, considering that the half-life is 1600 years, it means that the mass of Ra-226 is decreased.
Best regards.

a. actually participates in the reaction.
b. changes the equilibrium concentration of the products.
c. decreases the rate for a reaction.
d. increases the activation energy for a reaction.
The strength of an acid is affected by the polarity of the bond connected to the acidic hydrogen. The more highly polarized this bond, the more easily the hydrogen is ionized. Electronegative atoms or groups of atoms present in the structure of an acid can act to withdraw electrons and produce additional polarization. Two common groups of acids to which this principle can be applied are oxyacids and carboxylic acids. Arrange the following oxyacids in order of decreasing acid strength. Rank from strongest to weakest acid.
a. HBrO
b. HClO
c. HClO3
d. HClO2
Answer:
Explanation:
Oxyacids are acid containing oxygen; they are also known as acid-alcohol or acid-phenol. As said earlier, the strength of these acids increases with increases in the polarity of these compounds. So, what makes the polarity is as a result of the electronegative substituents attached to it. Halogen family possesses the highest electronegativity in the periodic table, and electronegativity decreases down the group.
The ranking of the oxyacids in order of decreasing acid strength from strongest to weakest acid is:
HClO3 > . HClO2 > HClO > HBrO
