 <span>HCl is a strong acid and NaOH is a strong base, so mixing them together will produce a lot of heat. The products are salt or Sodium chloride (NaCl) and water (H2O). Since one is an acid and one is a base they will neutralize each other. I hope this helps</span>

Answer:

The beaker feels warm because is an exothermic reaction

Explanation:

An exothermic reaction is one that releases energy, in this case, through heat. Then, when HCl, a strong acid, and NaOH, a strong base, are mixed together it is produced a salt and water with a release of energy. The reaction is expressed as:

HCl + NaOH ------> NaCl + HCl + Energy

This happens because the energy of the products is lower than the energy of the reactants.

A student analyzed an antacid tablet from a bottle containing 120 tablets purchased for $2.79. The mass of the tablet was 1.247
BaLLatris [955]

The cost of one antacid is 2.325 cents per tablet.

<u>Explanation:</u>

As per the question based on the student analysis we know that,

Total antacid tablets in a bottle = 120

Purchase Price of a bottle = $ 2.79

Cost of 1 antacid tablet =\frac{2.79}{120}  

As we know $1 = 100 cent

The cost of 1 antacid tablet = \frac{2.79}{120} × 100 cents = 2.325 cents/tablet .

Thus we came to know that it costs 2.325 cents/tablet .
