Okay, so what you first do with this type of question is think about what a chemical change is. A chemical change is a change that can not be reversed. A physical change is something that can be reversed or done using temperature. e.x. Water freezing into ice is a physical change, where as combining vinegar and baking soda together releases a gas, which is chemical, or iron rusting in the presence of oxygen. Which one of these equations has one chemical molecule set that produces a different set?
Answer:
Percent yield of carbon monoxide is approximately 38%.
Explanation:
Given reaction : C + SiO₂ → Si + CO
On balancing it : 2C + SiO₂ → Si + 2CO
⇒ 2 mole of carbon produces 2 mole of carbon monoxide
or 2×12=24 g of carbon produces 2×(12+16)=56 g of carbon monoxide
⇒ Expected yield of carbon monoxide when 32.5g of carbon is heated with silicon dioxide is 32.5×
⇒ Expected yield =
= 75.8 g
Actual yield is given as 28.8 g
⇒ The percent yield of carbon monoxide =
×100
=
×100
≅<u>38%</u>
