Answer:
1. naoh + h₂o → na⁺ + oh⁻ + h₂o + heat
2. naoh + hcl → nacl + h₂o
explanation:
1. the dissolving of naoh in water is an exothermic reaction resulting a heat. it also causes the dissociation of naoh to its ions (na⁺ and oh⁻).
so, the balanced equation will be naoh + h₂o → na⁺ + oh⁻ + h₂o + heat.
2. the reaction between acid and base resulting salt and water. it is considered as a neutralization reaction.
the reaction between hcl and naoh will give sodium chloride and water and the balanced equation will be naoh + hcl → nacl + h₂o.
Explanation:
Answer : The molarity of solution is, 1.216 g/mole
Explanation : Given,
Density of acetic acid = 1.049 g/ml (standard value)
Volume of acetic acid = 16.00 ml
Volume of solution = 230.0 ml
Molar mass of acetic acid 
= 
First we have to calculate the mass of acetic acid.
Now we have to calculate the molarity of solution.
Therefore, the molarity of solution is, 1.216 g/mole
kenetic energy is the answer i think
One kilogram is the answer
Answer: Option (c) is the correct answer.
Explanation:
A particle that contains two protons and two neutrons bounded together is known as an alpha particle.
It is known that an alpha particle has a large mass and due to this they travel very slowly. As a result, they tend to have low velocity.
Hence, we can conclude that alpha particles cannot penetrate deeply into solids because they have low velocity.
