distinguish between climate and atmosphere.
what type of bonding is occuring in the compound below?
Answer:
D.Metallic
Explanation:
The metallic model is often characterized as a "sea of electrons". This is because the electrons delocalize from the ion's orbitals, allowing them to roam freely around the substance. This is what the model is showing.

What is the molar concentration of 2.21 mil of KCI dissolved in 0.6068L of solution? explain why
Answer:
3.64M is the molar concentration of the solution
Explanation:
Molarity (Molar concentration, M) is an unit of concentration widely used in chemistry defined as the ratio between the moles of solute (In this case, KCl) and the volume of the solution in liters.
As you can see, the moles of KCl are 2.21 mol, and the volume of the solution is 0.6068L. The molarity is:
2.21mol / 0.6068L =
3.64M is the molar concentration of the solution

Two or more members of the same species living in the same habitat
Answer:
population - A group of organisms of the same species living in the same area at the same time, and which are capable of interbreeding. community - A group of populations living and interacting with each other in a common habitat.
Explanation:
The competitive exclusion principle tells us that two species can't have exactly the same niche in a habitat and stably coexist. That's because species with identical niches also have identical needs, which means they would compete for precisely the same resources.

The distance between an oxygen and hydrogen in a water in 95.98.What is the distance in meter nanometer and centimeters
Answer:
9.598 × 10⁻¹¹ m
0.09598 nm
9.598 × 10⁻⁹ cm
Explanation:
Step 1: Given data
Distance between oxygen and hydrogen in water (d): 95.98 pm
Step 2: Convert "d" to meters
We will use the conversion factor 1 m = 10¹² pm.
95.98 pm × 1 m/10¹² pm = 9.598 × 10⁻¹¹ m
Step 3: Convert "d" to nanometers
We will use the conversion factor 1 m = 10⁹ nm.
9.598 × 10⁻¹¹ m × 10⁹ nm/1 m = 0.09598 nm
Step 4: Convert "d" to centimeters
We will use the conversion factor 1 m = 100 cm.
9.598 × 10⁻¹¹ m × 100 cm/1 m = 9.598 × 10⁻⁹ cm

Assuming that the trends continue, which of the following compounds do you predict will have the GREATEST solubility at 120°C?
A.
Ce2(SO4)3
B.
K2Cr2O7
C.
Pb(NO3)2
D.
NaCl
Answer:
K2Cr2O7
Explanation:
Solubility refers to the amount of substance that dissolves in a given mass or volume of solvent. There are several units of solubility applicable in different areas.
Solubility is dependent on temperature. The solubility curve is a graphical representation of the dependence of solubility on temperature for different chemical species.
If we study the solubility curve closely, we will see that K2Cr2O7 has the highest solubility at 100°C. This means that if the trends continue, this substance will also have the highest solubility at 120°C.

5. (10 Points) To calculate the heat released in the reaction you used the formula
q=cmAT. What do each of the symbols represent in the this formula?
Explanation:
To calculate the heat released in the reaction, we use the formula-
Q = m×c×Δt
Where
Q - The heat energy
m - the mass of the object/substance being heated
c - the specific heat of the object/substance being heated
Δt - the change in temperature in °C

1. A mixture of 3 gases (A, B, and C) has a total pressure of 240kPa. If the partial pressure of
Gas A is 107 kPa and the partial pressure of Gas B is 55 kPa, what is the partial pressure of
Gas C?
Answer:
78 kPa
Explanation:
The total pressure is the sum of the partial pressures:
240 = Pa + Pb + Pc
240 = 107 + 55 + Pc
Pc = 78 kPa
Answer:
78 kPa

0.75 moles of an unknown acid are dissolved in water. If 0.42 moles of H3O+ form, what was the percent dissociation of the unknown acid?
Answer:
56 %
Explanation:
The percent dissociation of a weak acid can be defined as:
Moles of weak acid that produced H₃O⁺ species / Total number of weak acid moles * 100%
We are given all the required data to calculate the percent dissociation:
0.42 mol / 0.75 mol * 100 % = 56 %
The percent dissociation is 56%.
How many grams is 2.393 x 10^24 atoms of CI
70.45 g CI
140.9 ga
140.9 mole CI
70.45 mole CI
Answer:
There are 140.9 grams in 2.393*10²⁴ aotms of Cl.
Explanation:
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression. Avogadro's number applies to any substance.
Then you can apply the following rule of three: if 6.023*10²³ atoms are contained in 1 mole of the compound, 2.393*10²⁴ atoms are contained in how many moles?
[tex]amount of moles=\frac{2.393*10^{24} *1 mole}{6.023*10^{23} }[/tex]
amount of moles= 3.973
If the molar mass of Cl is 35.453 [tex]\frac{g}{mole}[/tex], then the amount of mass that contains 3.973 moles can be calculated as:
3.973 moles*35.453 [tex]\frac{g}{mole}[/tex]= 140.85 grams ≅ 140.9 grams
There are 140.9 grams in 2.393*10²⁴ aotms of Cl.
