Answer:
The balanced chemical equation is P₄ (s) + 5O₂ (g) → P₄O₁₀ (s)
Explanation:
In order to balance the chemical equation, you first need to see what's out of balance.
In this case our Oxygen is not balanced, so in order to make the two the same, we need to see what coefficient we need to add to the compounds to balance the problem.
So, adding a coefficient of 5 to the O₂ will result in an equal number of oxygen on both sides.
Answer:
Explanation:
2C₂H₂ + 5O₂ = 4CO₂ + 2H₂O .
CO₂ formed in moles = 33.4 / 44 = .76 moles
4 moles of CO₂ is formed by 2 moles of C₂H₂
.76 moles of CO₂ is formed by .38 moles of C₂H₂
.38 moles of C₂H₂ were present initially
2 moles of C₂H₂ produces 2 moles of water
.38 moles of C₂H₂ produces .38 moles of water
water produced = .38 moles
= .38 x 18 = 6.84 grams of water .

Explanation:
The oxidation number of chlorine can be -1, 0, +1, +3, +4, +5, or +7, depending on the substance containing the chlorine. The most common oxidation numbers are -1 (as in HCl and NaCl ) and 0 (as in Cl2 ).
