- Mass (m) = 1 Kg
- Acceleration due to gravity (g) = 9.8 m/s^2
- We know, weight = mass × acceleration due to gravity.
- Therefore, weight of the object
<h3>Answer:</h3>
B. 9.8 N

Answer: A reaction which occurs when equivalent quantities of H" (or ) and OH" are mixed is a neutralization reaction.
Explanation:
When acid and base chemically combine together to form sat and water then it is know as neutralization reaction.
An acidic substance gives hydrogen ions on dissociation and a basic substance gives hydroxide ions on dissociation.
For example, is a neutralization reaction where an acid and base are mixed together to form water.
No salt is formed as because here the reactants are not present as compounds.
In a hydrolysis reaction, water molecule(s) is added to the reactant molecules.
For example,
Oxidation is the process of addition of oxygen to a molecule and removal of hydrogen.
Reduction is the process of addition of hydrogen in a compound and the removal of oxygen atom.
Therefore, we can conclude that reaction which occurs when equivalent quantities of H" (or ) and OH" are mixed is a neutralization reaction.
