A chemical reaction is a process that can lead to a change of state, the outcome of a chemical reaction can ultimately lead to the formation of a new substance.
<h3>Types of Chemical Reactions</h3>
- Synthesis reactions
- Decomposition reactions
- Single-replacement reactions
- Double-replacement reactions
- Combustion reactions.

<u>Answer:</u>
<em>5 molecules of oxygen will be present
</em>
<u>Explanation:</u>
<em>In this reaction combustion is taking place hence there must be presence of oxygen in it.
</em>
We don't know the initial amount of carbon molecules in hydrogen molecules present hence the equation goes:-
Mass of fuel 16.74 grams, Mass of carbon dioxide is 1198 gram and water is 0.0654 remaining mass of fuel is 16.70 g. Hence amount of fuel used up is 0.04 gram
<em></em>
<em>Weight of products is 0.1852 and weight of oxygen is 0.1452
</em>
<em>No of molecules will be molecules
</em>
It should be sketch,identify, dig, then set water for the watering times, hope this helps, hope you feel better soon
False
The water is more buoyant which means the water has more of a tendency to float than the duck.
The question is incomplete, here is the complete question:
Write a balanced equation for the neutralization of calcium hydroxide by hydrochloric acid. What is the coefficient for hydrochloric acid in the reaction.
<u>Answer:</u> The balanced chemical reaction is written below and the coefficient of hydrochloric acid is 2.
<u>Explanation:</u>
Neutralization reaction is defined as the reaction in which an acid reacts with a base to produce a salt and water molecule.
Balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side will be equal to the total number of individual atoms on the product side. These equations follow law of conservation of mass.
The balanced chemical equation for the reaction of calcium hydroxide and hydrochloric acid follows:
By Stoichiometry of the reaction:
1 mole of calcium hydroxide reacts with 2 moles of hydrochloric acid to produce 1 mole of calcium chloride and 2 moles of water molecule.
Hence, the balanced chemical reaction is written below and the coefficient of hydrochloric acid is 2.
