Answer:

D. Water

Explanation:

Isotopes -

For some elements , there are various forms possible , which have different number of neutron and same number of protons , are referred to as the isotopes .

The three isotopes possible for the element hydrogen are -

Protium , Deuterium and Tritium .

Where ,

  • Protium has one electron , one proton and zero neutron.
  • Deuterium has one electron , one proton and one neutron.
  • Tritium has one electron , one proton and two neutron.

Deuterium is very rarely found on Earth , but can easily be prepared from water , which is known as deuterated water , which is helpful for isotopic labelling.

What change in volume results if 50 mL of gas is cooled from 30 C to 4 C
11111nata11111 [884]

The relation between the volume of the gas and the temperature is established by Charles's law. With a decrease in the temperature, the volume decreases by 45.7 mL. Thus, option c is correct.

<h3>What is Charle's law?</h3>

Charle's law states the direct relation present between the temperature and the volume of the gas. The law is given as:

V₁ ÷ T₁ = V₂ ÷ T₂

Given,

V₁ = 50 mL

T₁ = 303.15 K

T₂ = 277.15 K

Substituting the value the final volume is calculated as:

50 ÷ 303.15 = V₂ ÷ 277.15

V₂ = (50 × 277.15) ÷ 303.15

= 45.71 mL

Therefore, option c. 45.7 mL is the final volume.

. What happens the pH of an acid solution as a base is added?​
Dmitrij [34]

As a base is added to an acidic solution, the H+ ions in solution that make it acidic are slowly neutralized into water (via OH-, the base). As these ions are converted into water the concentration of them decreases, so the pH decreases, as they are directly related.

Hope this helps!
