Question

To balance the equation, what coefficient should be placed in front of the Ag? Ag has Agas H2.

Options:
a) 1
b) 2
c) 3
d) 4

Answer 1

The correct coefficient to balance the given chemical equation by ensuring the number of hydrogen atoms on both sides is equal would be 'd) 4', assuming the formation of Silver hydride (AgH) with one hydrogen per silver atom.

Step-by-step explanation:

To balance the chemical equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. When dealing with the incomplete equation where Ag (Silver) reacts with H2 to form a product (not fully provided in the question), and given no other product details, we must infer the possible reaction. However, given the options provided and the standard formation of Silver hydride (AgH), we would expect the equation to balance if we ensure the number of hydrogen atoms on both sides is equal.

A suitable coefficient must be chosen for Ag in this scenario. Let's assume the formation of AgH which requires one H atom for every Ag atom, so if we have 2 H2 molecules as reactants (each providing 2 H atoms for a total of 4 H atoms), we'd need to combine them with 4 Ag atoms to form 4 AgH molecules. Therefore, the coefficient for Ag should be 4. This would look like:

4Ag + 2H2 → 4AgH

Hence, the correct coefficient to place in front of Ag in this case is 'd) 4'.
