The answer is D. easier, higher
B. should be the correct answer.
since the transmisition of electrons from higher to lower energy levels involves energy release represented in the visible light we see
The reaction between methane gas and chlorine gas to form hydrogen chloride and carbon tetrachloride, all in their gaseous form can be expressed through the chemical reaction below.
CH₄ + 4Cl₂ --> 4HCl + CCl₄
Let us assume that all the involved gases behaves ideally such that each mole of the gas is equal to 22.4 L.
Through proper dimensional analysis, the volume of the produced hydrogen chloride is calculated,
V(HCl) = (1.69 mL CH₄)(1 L CH₄/ 1000 mL CH₄)(1 mol CH₄/22.4 L CH₄)(4 mols HCl/1 mol CH₄)(22.4 L HCl/1 mol HCl)(1000 mL/1 L)
V(HCl) = 6.76 mL
<em>ANSWER: 6.76 mL</em>
782g
Explanation:
Given parameters:
Number of moles of N₂ = 23moles
Unknown:
Mass of NH₃ = ?
Solution:
We first obtain the balanced chemical equation for this reaction;
N₂ + 3H₂ → 2NH₃
From the equation we see that;
1 mole of N₂ produced 2 moles of ammonia
23 mole of N₂ will yield 2 x 23 = 46moles of ammonia
Now ;
mass of ammonia = number of moles x molar mass
Molar mass of NH₃ = 14 + 3(1) = 17g/mol
Mass of ammonia = 46 x 17 = 782g
