Explanation:
Answer:
Reactants: Ethanol (C₅H₅OH), Oxygen (O₂)
Products: Carbon dioxide (CO₂) and Water (H₂O)
Explanation:
Let’s rewrite each part of the described situation in chemical equation terms.
Ethanol - C₂H₅OH
is burned in the prescence of - +
oxygen - O₂
producing - →
carbon dioxide - CO₂
and - +
water - H₂O
Chemical equation:
C₂H₅OH + O₂ → CO₂ + H₂O
The terms on the left side of a chemical equation are reactants, and the terms on the right side of a chemical equation are products.
Therefore, since we know this, ethanol (C₂H₅OH) & oxygen (O₂) are the reactants, and carbon dioxide (CO₂) & water (H₂O) are the products.

Use an arbitrary mass, 100 g is an easy number to work with.
60% of 100 g is 60 g, there are two A's. Each A is 30 g
40 g is B, and there is only one, so B is 40 g.
<span>A<span>B2</span></span>, would have a mass of 30 g + 2*40 g = 110 g
The new percent by mass composition of A is: <span><span><span>30g</span><span>110g</span></span>∗100%=27.3%</span>
The new percent by mass composition of B is: <span><span><span><span>80g</span><span>110g</span></span>∗100%=72.7%</span></span>
The balanced reaction equations are;
a) 4 NaClO + H2S → 4 NaCl + H2SO4
b)6Ce^4+ + I^– + 6OH^– → 6 Ce^3+ + IO3^– + 3H2O
<h3>What is a balanced redox reaction?</h3>
A redox reaction is said to be balanced when the number of electrons gained is equal to the number of electrons lost.
Let us now write the balanced reaction equations one after the other. Thus;
a) 4 NaClO + H2S → 4 NaCl + H2SO4
b)6Ce^4+ + I^– + 6OH^– → 6 Ce^3+ + IO3^– + 3H2O
