Answer:
3.94 × 10³ g
Explanation:
Step 1: Write the neutralization reaction
HClO₃ + NaOH = NaClO₃ + H₂O
Step 2: Calculate the moles of chloric acid that react
25.5 L of 3.86 M chloric acid is to be neutralized. The reacting moles are:
Step 3: Calculate the required moles of sodium hydroxide
The molar ratio of HClO₃ to NaOH is 1:1. Then, the reacting moles of NaOH are 98.4 moles.
Step 4: Calculate the mass of sodium hydroxide corresponding to 98.4 moles
The molar mass of NaOH is 40.00 g/mol.
<u>Answer:</u> The correct option is C) decomposition
<u>Explanation:</u>
Single displacement reaction is defined as the reaction where a more reactive element displaces a less reactive element from its salt solution.
Element B is more reactive than element A
Double displacement reaction is defined as the reaction where an exchange of ions takes place in a solution
Decomposition reaction is defined as the reaction where a single large chemical species breaks down into two or more smaller chemical species.
Synthesis reaction is defined as the reaction where two or more smaller chemical species combine together in their elemental state to form a single large chemical species.
For the given chemical reaction:
Here, water is breaking down into two smaller species of oxygen and hydrogen gas. Thus, it is a decomposition reaction.
Hence, the correct option is C) decomposition
