The answers for the following questions is answered below.
- Therefore the volume of a gas is 22.4 L
- <u>Therefore the number of moles of oxygen are 2.37 moles</u>
Explanation:
1. Given:
no of molecules (n) = 6.023 × 
volume of gas at STP conditions (V) =22.4 liters
To solve:
Volume of gas (v)
We know;
1 × 22.4 = v
v =22.4 L
Therefore the volume of a gas is 22.4 L
2. Given:
volume of oxygen gas (v) = 53 L
Volume of gas at STP conditions (V) =22.4 L
To solve:
no of moles of oxygen gas
We know;
n =
n =2.37 moles
<u>Therefore the number of moles of oxygen are 2.37 moles</u>
<u></u>
Answer:
Reactants: K = 2, S = 1, Co = 1, Cl = 2; Products: K = 2, S = 1, Co = 1, Cl = 2
Explanation:
The reaction is a double replacement reaction so the anions (Cl⁻ and S²⁻) switch places.
<u>1</u> K₂S + <u>1</u> CoCl₂ ⇒ <u>2</u> KCl + <u>1 </u>CoS (balanced chemical equation)
On the reactants and products side, K = 2, S = 1, Co = 1, and Cl = 2.
Hope that helps.
The reaction mixture of problem 1 includes <span>10mL of 4.0 M acetone = 10 mL 1.0 M HCl = 10 mL 0.0050 M I2 = 20 mL H2O. if this is true then the procedure is the following:
In order to find the total volume of reaction then you need to do like this:
</span><span>V = 10 mL + 10 mL + 10 mL + 20 mL = 50 mL </span>
<span>[I2]o = (0.005 mol I2 / 1 L I2 solution) (10 mL I2 solution) / 50 mL = 0.001 M </span>
<span>To first order, the reaction rate is 0.001 M / 230 s = 4,3 e-6 M/s
Then if you want to find the rate yoe need to use the following formula:
</span><span> k [CO(CH3)2]^a [I2]^b [HCl]^c
</span>So: <span>4,3 e-6 = k (4 M * 10 mL / 50 mL)^a (1e-3 M)^b (1 M * 10 mL / 50 mL)^c

Chemical or molecular formulas? Symbols from the periodic table are used to show which atoms are present in a molecule and subscripts show the number of atoms and of each type in the molecule.
