Question

does your initial reaction still seem accurate? select all that apply.
yes, because it shows that hydrogen gas reacts with oxygen to produce water.
no, because the number of reactants is greater than the number of products.
no, because the number of oxygen atoms on the left is not equal to the number of hydrogen atoms on the right.
no, because the number of hydrogen atoms on both sides of the equation is not balanced.
no, because the equation defies the law of conservation of mass.
no, because the number of oxygen atoms on the reactants side is not the same as on the products side.

Explanation:

• The law of conservation of mass states that matter is neither created nor destroyed in a chemical reaction. This means the number of atoms of each element must be the same on both sides of the equation.
• Let's count the atoms:
• Oxygen atoms:
• Reactants: There are \(2\) oxygen atoms (from the \(O_2\) molecule).
• Products: There is \(1\) oxygen atom (from the \(H_2O\) molecule). So, oxygen atoms are not balanced.
• Hydrogen atoms:
• Reactants: There are \(2\) hydrogen atoms (from the \(H_2\) molecule).
• Products: There are \(2\) hydrogen atoms (from the \(H_2O\) molecule). Hydrogen atoms are balanced.
• Since oxygen atoms are not balanced, the equation defies the law of conservation of mass.

Answer:

No, because the equation defies the law of conservation of mass.
No, because the number of oxygen atoms on the reactants side is not the same as on the products side.
