Answer:
Amino Acids
Explanation:
What Are Proteins Made Of? The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain.
Period
Group
Explanation:
On the periodic table the numbers 1,2 and 3 can represent either groups or periods.
The periodic table gives the arrangement of elements based on their atomic numbers
- They are divided into vertical columns and horizontal rows
- The vertical columns are the groups whereas the horizontal rows are the periods.
- The vertical columns are made up of elements having the same number of electrons in their outermost shell.
- The horizontal columns are made up of elements having the same number of shell.
- On the periodic table, the groups are numbered 1 - 18
- There are 7 periods on the table.

Answer:
64.0 g/mol.
Explanation:
- Thomas Graham found that, at a constant temperature and pressure the rates of effusion of various gases are inversely proportional to the square root of their masses.
<em>∨ ∝ 1/√M.</em>
where, ∨ is the rate of diffusion of the gas.
M is the molar mass of the gas.
<em>∨₁/∨₂ = √(M₂/M₁)</em>
∨₁ is the rate of effusion of the unknown gas.
∨₂ is the rate of effusion of He gas.
M₁ is the molar mass of the unknown gas.
M₂ is the molar mass of He gas (M₂ = 4.0 g/mol).
<em>∨₁/∨₂ = 0.25.</em>
∵ ∨₁/∨₂ = √(M₂/M₁)
∴ (0.25) =√(4.0 g/mol)/(M₁)
<u><em>By squaring the both sides:</em></u>
∴ (0.25)² = (4.0 g/mol)/(M₁)
∴ M₁ = (4.0 g/mol)/(0.25)² = 64.0 g/mol.
