Why is freshly distilled or deionized water used in this standardization?

The amount of carbon dioxide is little in deionized water.

Explanation:

Deionized water is a water with little or no impurities. Impurities are in waters are not able to boil below or above the boiling point of water,and in this case are been retained in the original container.

There is little CO2 in freshly deionized or distilled water.

Explanation:

Freshly distilled water has no hydrogen peroxide. Distilled water contains calcium, which stabilizes the sodium hydroxide , Freshly deionized water has a pH of 4.72. There is little CO2 in freshly deionized or distilled water.

a) the event horizon, singularity, and the chute located between the two.

answer: the potential energy decreases from 379 j to 243 j

explanation:

for the law of conservation of energy, the total energy in a system must be conserved. the total energy of the system is given by the sum of kinetic (k) and potential (u) energy:

e = k + u

the total energy is e=675 j, and this does not change.

initially, the kinetic energy is k=296 j, so the potential energy is

at the end, the kinetic energy is k=432 j, so the potential energy is

so, we see that the potential energy has decreased from 379 j to 243 j.
