Answer:
I believe the ans is FeO and Cl2
Answer:
[tex]\boxed {\boxed {\sf FeO and Cl_2}}[/tex]
Explanation:
In a chemical reaction, there are reactants and products.
The reactants are the substances at the beginning of the reaction. They go into the reaction and are changed.
The products are the substances created in the reaction and what you end up with after the reaction.
In an equation, the reactants are to the left of the arrow and the products are to the right.
Let's look at the equation given:
[tex]2FeO+ 2Cl_2 \rightarrow 2FeCl_2+O_2[/tex]
FeO and Cl₂ start the reaction and are to the left of the arrow, so they must be the reactants.

Electricity generated from any source comes with its own advantages and
disadvantages. So, no source of energy for generating electricity is perfect. However,
imagine that there is an energy source that perfectly meets the needs of society.
Describe this ideal source of energy. Include relevant factors such as cost, supply, safety,
reliability, and environmental impact
Answer:
Wind energy
Explanation:
An ideal source of energy needs to be reliable, cost effective, safe and must lead to almost zero adverse environmental impact.
Wind energy is energy obtained from air moving at high velocity. This energy is harvested using windmills which convert mechanical energy to electrical energy.
Wind is inexpensive because it occurs naturally. However, a large expanse of land is required in order to mount sufficient number of windmills that will generate enough electrical energy for practical purposes.
This method of electricity generation is safe and does not lead to any environmental hazard unlike the burning of fossil fuels, use of nuclear energy or loss of habitat due to hydroelectric power generation.

if a 119g sample of water was allowed to evaporate completely, what volume of water vapour would be produced in milliliters?
As 1 L = 1000 g
so 119 grams = 0.119000 L
Hope it is helpful to u
If yes then plz mark me brainlest
We are given:
Mass of water: 119 grams
We know that one mole of a gas occupies 22.4L of volume
Number of moles of water:
Number of moles = given mass / Molar mass
Number of moles = 119 / 18 [molar mass of water = 18 grams/mol]
Number of moles = 6.61 moles
Volume occupied:
Volume = number of moles * 22.4 L
Volume = 6.61 * 22.4
Volume = 148L
Volume (in mL) = 1.48 * 10⁻¹ mL

669.0 mL of oxygen are collected over water at 17.0 °C and a total
pressure of 785.0 mm of mercury. What is the volume (in mL) of dry
oxygen at 60.0 °C and 847.0 mmHg pressure?
Question 5
2 pts
Answer:
711.96 mL
Explanation:
Using the combined gas law equation;
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (mmHg)
P2 = final pressure (mmHg)
V1 = initial volume (mL)
V2 = final volume (mL)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information provided in this question,
P1 = 785.0 mmHg
P2 = 847.0 mmHg
V1 = 669.0 mL
V2 = ?
T1 = 17.0 °C = 17 + 273 = 290K
T2 = 60.0 °C = 60 + 273 = 333K
Using P1V1/T1 = P2V2/T2
785 × 669/290 = 847 × V2/333
525165/290 = 847 V2/333
1810.91 = 2.54 V2
V2 = 1810.91 ÷ 2.54
V2 = 711.96 mL
Which is true regarding pressure?
A.) at high pressure, the molecules are moving slower and therefore hitting other particles and the sides of a container less frequently
B.) pressure is calculated by combining the amount of space an entire object takes up.
C.) pressure is calculated by averaging the kinetic energy of all particles in a container
D.) at higher pressure indicates that particles are colliding with the walls of a container more frequently
Answer:
D
Explanation:
The higher a pressure in a system the faster the molecules within it move and collide with one another due to lack of space
What is the volume of the gas if there are 3.20 mol of gas at 265 K and 2.50 atm of pressure?
Answer:
27.81 L
Explanation:
Assuming the gas is ideal, we can solve this problem by using the following formula:
PV = nRTWhere:
P is Pressure, 2.50 atmV is Volumen is the number of moles, 3.20 molR is a constant, 0.082 atm·L·mol⁻¹·K⁻¹T is temperature, 265 KWe input the data:
2.50 atm * V = 3.20 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 265 KAnd solve for V:
V = 27.81 Lwhat is the difference between Earth and Exoplanets

A weather balloon calibrated at 0.00 degrees Celsius to have a volume of 20.0 L has what volume in L at -22.8 degrees Celsius pressure is held constant?
Answer:
New volume = 18.33 L
Explanation:
Given that,
Initial temperature, [tex]T_1=0^{\circ} C=273.15\ K[/tex]
Initial volume, [tex]V_1=20\ L[/tex]
Final temperature, [tex]T_2=-22.8^{\circ}C=250.35\ K[/tex]
We need to find the final volume when pressure is held constant. The relation between volume and temperature is given by :
[tex]V\propto T\\\\\dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}\\\\V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{20\times 250.35}{273.15}\\\\V_2=18.33\ L[/tex]
So, the new volume is equal to [tex]18.33\ L[/tex].

Given the reaction: N2(g) +2O2(g) ⇌ 2NO2(g) The forward reaction is endothermic. Determine which of the following changes would result in more product being produced.
I. Increase NO2
II. Decrease O2
III. Add a catalyst
IV. Increase the temperature
V. Increase the pressure
A. I and II
B. II, III, and V
C. IV and V
D. II and IV
Answer:
C
Explanation:
increasing the temperature will favour the forward reaction therefore the reaction system will try to counteract that by producing more heat and NO2 therefore increases the amount of products produced
increasing the pressure will favour the forward reaction as it has more moles of substance therefore if the forward reaction is favored, more product will be produced

What happens to iron when it melts?
O A. It undergoes a chemical change.
O B. It undergoes a physical change.
O c. Its atoms break apart and form new atoms.
O D. Its atoms combine and form new atoms.
Answer:
B. It undergoes a physical change.
Explanation:
Hello there!
In this case, since we know that chemical changes lead to the formation of new atoms and/or compounds due to the bonds rearrangement of the initial substances and the physical changes occur without changing the composition of the initial substances, we can infer that, since melting is a process that changes the phase of matter from solid to liquid without changing the identity of the initial substance, the answer to this question would be B. It undergoes a physical change. because the other options describe chemical changes.
Best regards!
Answer:
B. It undergoes a physical change.
Explanation:
At room temperature, the iron atoms are in an unusual loosely packed open arrangement; as iron is heated past 912 degrees Celsius, the atoms become more closely packed before loosening again at 1,394 degrees Celsius and ultimately melting at 1,538 degrees Celsius.
ch3-co-ch2-ch2-ch3 IUpAC name
Answer:
2-pentanone.
Explanation:
Hello there!
In this case, for the given compound and, in agreement with the octet rule, it is possible to realize that the CO is actually C=O as shown below:
CH3 - C - CH2 - CH2 - CH3
||
O
Thus, since the C=O stands for the carbonyl group within the parent chain, we infer this is a ketone and more specifically 2-pentanone as it has five carbon atoms.

What is the limiting reactant when 1.50 g of lithium and 1.50 g of nitrogen combine to form lithium nitride, a
component of advanced batteries, according to the following unbalanced equation?
Li + N2 ⟶ Li3 N
Answer:
Li is limiting reactant
Explanation:
Based on the reaction:
6Li + N2 → 2Li3N
Where 6 moles of Li reacts per mole of N2
To solve this question we must convert the mass of each reactant to moles and using the chemical equation we can find limiting reactant
Moles Li -6.941g/mol-
1.50g * (1mol / 6.941g) = 0.2161 moles Li
Moles N2 -Molar mass:28g/mol-
1.50g * (1mol / 28g) = 0.0536 moles N2
For a complete reaction of 0.536 moles N2 are needed:
0.536 moles N2 * (6mol Li / 1mol N2) = 0.3214 moles Li
As there are just 0.2161 moles of Li
Li is limiting reactantThe electrolyte magnesium chloride (MgCl2) will break up into how many individual particles in water (what is the i value)?
Answer:
Solid magnesium chloride is a non-conductor of electricity because the ions aren't free to move. However, it undergoes electrolysis when the ions become free on melting. Magnesium chloride dissolves in water to give a faintly acidic solution (pH = or 6).
