<h3>
The supplements that are minerals are</h3>
- calcium
- sodium
- iron
- zinc
<u><em> Explanation</em></u>
- calcium and sodium are major minerals which are required by the body for
calcium- needed for muscle,hearing bone and for the support of synthesis and function of cells
sodium- is needed to control blood pressure and also for proper muscle and nerve function
- Zinc and iron are required in trace and both are needed for good health
When two atoms combine, the overlap of their atomic orbitals produces molecular orbitals.
The element Sodium (Na) has 11 protons and 1 valence electron.
Answer:
Fluorine
Explanation:
Fluorine has the greatest attraction for electrons in any bond that it forms. The attraction of an atom for shared electrons is called its electronegativity.
Answer : The partial pressure of
and
are, 84 torr and 778 torr respectively.
Explanation : Given,
Mass of
= 15.0 g
Mass of
= 22.6 g
Molar mass of
= 197.4 g/mole
Molar mass of
= 32 g/mole
First we have to calculate the moles of
and
.

and,

Now we have to calculate the mole fraction of
and
.

and,

Now we have to partial pressure of
and
.
According to the Raoult's law,

where,
= partial pressure of gas
= total pressure of gas
= mole fraction of gas


and,


Therefore, the partial pressure of
and
are, 84 torr and 778 torr respectively.
