Deuterium is a relatively uncommon form of hydrogen, but can be created from water.
- Heavy hydrogen commonly known as deuterium
- stable isotopes of hydrogen
- gets its name from the Greek word deuterons means second.
- has only one proton and one neutron
- nucleus of the hydrogen's deuterium atom is known as a deuteron containing one proton and one neutron.
- Deuterium forms chemical bonds that are stronger than regular hydrogen
- gas deuterium is colorless
- Deuterated water is used in Magnetic Resonance Spectroscopy.
- used in the determination of the isotopologue of various organic compounds.
- used in Infrared Spectroscopy.

When the initial concentration of crystal Violet is double, the rate of the reaction will rise up about four times the initial rate.
<h3>What is the rate of chemical reaction?</h3>
The rate of a chemical reaction refer to the rate of change in concentration of the reaction over the change in time. Introduction.
When you double the concentration the rate doubles. The rate is proportional to the square of the concentration of a reactant. When the rate is doubled the concentration rate goes up four times. The rate is not affected by the concentration of a reactant.

The answer is c electrostatic repulsion between nuclei
Answer: only Br2.
Justification.
In a chemical reaction the element that gains electrons experiments a reduction in its oxidation state, that is why it is said that it is reduced.
So, to know what element is being reduced you need to calculate the oxidation states of the elements involved.
Here I indicate the oxidation states of each element if the reaction putting them inside parenthesis:
Reactants side Products side
K (0) K (1+)
Br (0) Br(1-)
So, K lost one electron, increasing its oxidation statefrom 0 to 1+, meaning that it is being oxidized.
And, each atom of Br gained one electron, reducing its oxidation state from 0 to 1-, meaning it is being reduced.
Therefore, the answer is that Br2 is the substance being reduced.
Explanation:
It is known that molarity is the number of moles present in a liter of solution.
Molarity = 
Also, number of moles equal mass divided by molar mass. And, molar mass of calcium is 40.07 g/mol.
No. of moles = 
= 
= 0.025 mol
Therefore, calculate the molarity as follows.
Molarity =
= 
= 0.025 M
Thus, we can conclude that molarity of 
in milk is 0.025 M.
