<span>2 H</span>₂<span> + O</span>₂<span> = 2 H</span>₂<span>O

4 g H</span>₂ ------------ 32 g O₂----------- 36 g H₂O
<span> 8 g H</span>₂ ------------ 64 g O₂------------ ? g H₂O
<span>
Mass of H</span>₂O :
<span>
64 * 36 / 32 = 

2304 / 32 =  72 g of H</span>₂O
<span>
hope this helps!

Which is the most likely to be reduced?
NISA [10]

Answer : The correct option is, Zn^{2+}

Explanation :

  • Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. That means, the loss of electrons takes place.

Or we can say that, oxidation reaction occurs when a reactant losses electrons in the reaction.

  • Reduction reaction : It is defined as the reaction in which a substance gains electrons. That means, the gain of electrons takes place.

Or we can say that, reduction reaction occurs when a reactant gains electrons in the reaction.

According to the electrochemical series, Zn^{2+} most likely to be reduced because

Hence, the ion most likely to be reduced is Zn^{2+}.
