Question

in the equation given below, identify the...
$2h_2 + o_2 \
ightarrow 2h_2o$
a. 2h2o
b. h
c. o
d. 2

Explanation:

The question is about identifying a symbol in a chemical equation. In the equation \(2H_2 + O_2
ightarrow 2H_2O\), we analyze each option:

• Option a: \(2H_2O\) is a compound (product), not a symbol.
• Option b: \(H\) is the chemical symbol for Hydrogen.
• Option c: \(O\) is the chemical symbol for Oxygen, but let's check the context. Wait, the question might be about identifying the symbol (element symbol). \(H\) is the symbol for Hydrogen, which is present in the reactants and products.
• Option d: \(2\) is a coefficient, not a chemical symbol.

So the correct option is b as it is the chemical symbol for the element Hydrogen.

Answer:

b. H
