The number of grams of Cl2 formed when 0.385 mol HCl reacts with an excess of O2 is 13.6675 g.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 ×
of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Given data:
Moles of hydrochloric acid = 0.385 mol
Mass of chlorine gas =?
Chemical equation:
4HCl + O₂ → 2Cl₂ + 2H₂O
Now we will compare the moles of Cl₂ with HCl.
HCl : Cl₂
4 : 2
0.385 : 2÷4× 0.385 = 0.1925 mol
Oxygen is present in excess that's why the mass of chlorine produced depends upon the available amount of HCl.
Mass of Cl₂ :
Mass of Cl₂ = moles × molar mass
Mass of Cl₂ =0.1925 mol × 71 g/mol
Mass of Cl₂ = 13.6675 g
Hence, the number of grams of Cl2 formed when 0.385 mol HCl reacts with an excess of O2 is 13.6675 g.

#SPJ1
Substance a is a base, and substance b is an acid
Answer:
D. 11686.076 cm^3.
Explanation:
Assuming that this is a prism the volume is:
5.54 * 10.6 * 199
= 11686.076 cm^3.
Answer:
<h2>C 28 tonnes</h2>
Explanation
7 tonnes-8.5 ammonia
1 ton will be 8.5/7=1.21
we now know what 1 ton of nitrogen is equal to
so now,34/28 that is equal to 1.21
1.21=1.21
So the answer would be C. 28 tonnes
Thanks!
