As the temperature of a substance increases, the kinetic energy of the molecules _____________ and they begin to move __________
Dimas [21]

Answer:

The correct answer is "increase; faster".

Explanation:

The kinetic energy is defined as the power that an object has result of its movement. The kinetic energy of a substance has a direct relation with the temperature. As the temperature rises, the kinetic energy of the molecules increases, result of an increase in the speed of its movement. A higher temperature causes that the particles vibrate faster, which increases the kinetic energy.

What are the products of the acid-base reaction between HNO3 and NaOH? A. H2O and NaNO3 B. NaH and NO3OH C. HNOH and NaO3 D. NaO
Otrada [13]

Answer:- A. H_2O and NaNO_3

Explanations:- In general, acid+base\rightarrow salt+water

In acid-base reaction the acid gives hydrogen ion and the base gives hydroxide ion and these ions combine to form water. Rest of the ions from acid and base combine to form the salt.

Nitric acid breaks to give hydrogen ion and nitrate ion. Similarly, NaOH breaks to give sodium ion and hydroxide ion. Since, hydrogen ion and hydroxide ions form water, the sodium ion and nitrate ion forms the salt, sodium nitrate.

The reaction is shown as:

HNO_3(aq)+NaOH(aq)\rightarrow NaNO_3(aq)+H_2O(l)

So, the right choice is A.
