3 0

Answer:

B. Respiration

Explanation:

cellular respiration is the process where cells use glucose (C6H12O6) and oxygen gas (O2) to make carbon dioxide (CO2) water (H2O) and ATP, which is energy

formula:

C6H12O6 + 6O2 -> 6CO2 + 6H20 + 38ATP

Temka [501]

Uranium has three common isotopes. The average atomic mass of uranium is 23.7 u/atom.

<h3>What are isotopes?</h3>

Isotopes are similar elements that have a different number of protons.

Uranium has three isotopes

The abundance of 2U has an atomic mass of 233.878 is 0.01%

The abundance of U has a mass of 234.892 amu is 0.71%

The **U has an atomic mass of 237.911 amu is 99.28%

Let's assume we have 10 000 atoms of Uranium

Mass of the 0.01 atoms = 0.01 x 233.878 = 2.33878

Mass of the 0.71 atoms =  0.71 x 234.892 = 166.773

Mass of the 99.28 atoms = 99.28 x 237.911 = 23,619.80

2.33878 + 166.773 + 23,619.80 = 23,788.8

23,788.8 / 1000 = 23.7 u/atom

Thus, the average atomic mass of uranium is 23.7 u/atom.

Calcium nitrate and calcium carbonate are both ionic compounds.
VladimirAG [237]

Answer:

Calcium nitrate is soluble in water and dissociate into ions whereas calcium carbonate is insoluble and water and do not form ions.

Explanation:

An electrolyte is a substance which conducts electricity in molten form or when dissolved in water.

The ability of an electrolyte to conduct electricity is due the movement of charged particles called ions. The ions are of two types: negatively charged ions called anions and positively charged ions called cations.

Calcium nitrate is a soluble in water, and when dissolved in water produces two ions; negatively charged nitrate ions,NO₃⁻, and positively charged calcium ions, Ca²⁺. These ions enable it to conduct electricity.

Calcium carbonate on the other hand is insoluble in water, and thus, do not produces any ions capable of carrying current.
