How is hydrogen in heavy water different from hydrogen in normal water?
A. The hydrogen atoms in heavy water have a neutron in the nucleus,
doubling the mass.
B. The hydrogen atoms in heavy water have an extra proton in the
nucleus.
O
C. The hydrogen in heavy water is radioactive.
O
D. The heavy water molecules contain 3 hydrogen atoms instead of
Hydrogen in heavy water different from hydrogen in normal water as the hydrogen atoms in heavy water have a neutron in the nucleus,doubling the mass.
An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Answer:
Explanation:
Heavy water (deuterium oxide, 2
H
2O, D
2O) is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium (2
H or D, also known as heavy hydrogen), rather than the common hydrogen-1 isotope (1
H or H, also called protium) that makes up most of the hydrogen in normal water.[4] The presence of deuterium gives the water different nuclear properties, and the increase of mass gives it slightly different physical and chemical properties when compared to normal water. It can be used to create ice and snow at higher temperatures since its melting point is 3.82 C.
Answer:
Iron can not form iron(i) selenide however it can form iron(ii) selenide.
Explanation:
The possible oxidation states of iron are +2 and +3.
Iron can form iron (ii) selenide.
The formula of iron (ii) selenide is FeSe.
In iron (ii) selenide the oxidation state of iron is +2.
The ratio of both atoms are 1:1.
Its molecular weight is 134.82 g/mol.
It is toxic compound.
Its melting point is 965°C.
Its density is 4.72 g/cm³.
Iron can also form iron (iii) selenide.
The formula of iron (iii) selenide is Fe₂Se₃.
In iron (iii) selenide the oxidation state of iron is +3.
The ration of both atoms are 2:3.
It also known as ferric selenide.
Its molecular weight is 348.57 g/mol.
