As you move from right to left on the periodic table the atomic radius <u>decreases</u>

<u>Explanation:</u>

  1. On moving left to right across a period, the atomic number increases.
  2. Due to this the effective nuclear charge also increases.
  3. It implies that the nucleus pull is high for the electrons, due to which the atomic radius decreases.
  4. The diagram is attached below:

e) The heating of sodium carbonate to produces sodium oxide and carbon dioxide

Solution given:

<u>Balanced</u><u> </u><u>chemical</u><u> </u><u>equation</u><u>:</u>

\boxed{\bold{\green{Na_{2}CO_{2} +heat \rightarrow Na_{2}O +CO_{2}}}}

<u>when sodium carbonate is heated it decomposed and form sodium oxide and carbon dioxide</u>

<u>Balanced chemical equation:</u>

\boxed{\bold{\green{2Cr(OH)_{3}+ 3H_{2}SO_{4} → Cr_{2}(SO_{4})_{3} + 6H_{2}O}}}

<u>When chromium (III) hydroxide react with sulfuric acid double displacement takes place and forms produce chromium(III) sulfate and water.</u>

g) aluminum metal plus chlorine gas

\boxed{\bold{\green{2Al(s) + 3Cl_2(g) \rightarrow 2AlCl_2 }}}

A student determines the iron(III) content of a solution by first precipitating it as iron(III) hydroxide, and then decomposing
Semmy [17]

Answer:

3.3535 g

Explanation:

Considering:

Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}

Or,

Moles =Molarity \times {Volume\ of\ the\ solution}

Given :

For iron(III) nitrate :

Molarity = 0.404 M

Volume = 52.0 mL

The conversion of mL to L is shown below:

1 mL = 10⁻³ L

Thus, volume = 52.0×10⁻³ L

Thus, moles of iron(III) nitrate :

Moles=0.404 \times {52.0\times 10^{-3}}\ moles

Moles of iron(III) nitrate  = 0.021 moles

1 mole of iron(III) nitrate forms 1 mole of iron(III) hydroxide which further forms 1 mole of  iron(III) oxide.

Thus, moles of  iron(III) oxide formed from 0.021 moles of iron(III) nitrate = 0.021 moles

Also, molar mass of iron(III) oxide = 159.69 g/mol

So, mass of iron(III) oxide = 0.021 moles × 159.69 g/mol = 3.3535 g
