Classify each chemical compound listed in the table below.

prisoha [69]

Answer:

Please find attached the table of classification of the chemical compounds, created with Microsoft Word

Explanation:

The given compounds are;

H₂SO₃ is an acid which is known as sulfurous acid

When SO₂ is added to water, we have;

SO₂ + H₂O ⇄ HSO₃ + H⁺

Therefore, H₂SO₃ is ionic

2) HI which is known as hydrogen iodide, dissolves in water as follows

HI (g) + H₂O (l) ⇄ H₃O⁺(aq) + I⁻(aq)

Therefore, HI is able to donate hydrogen ions therefore, it is both acidic and ionic

3) KI is a salt of the alkali metal, potassium, and iodine which is a group 7 element such that it formed by the transfer of electrons from potassium to iodine making it an ionic compound

KI forms a slightly alkaline solution

4) NaClO₃ comprises of the ionic combination of sodium and chlorate ions which dissolves in water as follows;

NaClO₃ → Na⁺(aq) + ClO₃⁻(aq)

Therefore, NaClO₃ is ionic

NaClO₃ is also a strong oxidizing agent, making a Br∅nsted acid

we have;

Sulfurous acid (also Sulfuric(IV) acid, Sulphuric acid (UK), Sulphuric(IV) acid (UK)) is the chemical compound with the formula H2SO3. There is no evidence that sulfurous acid exists in solution, but the molecule has been detected in the gas phase.[1] The conjugate bases of this elusive acid are, however, common anions, bisulfite (or hydrogen sulfite) and sulfite.

Calculate the mass (g) of 1.5 moles of Sulfur.

just olya [345]

Answer:

48 g S

Explanation:

Step 1: Define

Molar Mass of Sulfur (S) - 32.07 g/mol

Step 2: Use Dimensional Analysis

$1.5 \hspace{3} mol \hspace{3} S(\frac{32.07 \hspace{3} g \hspace{3} S}{1 \hspace{3} mol \hspace{3} S} )$ = 48.105 g S

Step 3: Simplify

We have 2 sig figs.

48.105 g S ≈ 48 g S

A sample of pure lithium carbonate contains 18.8% lithium by mass. What is the % lithium by mass in a sample of pure lithium car

VashaNatasha [74]

Answer:

There is 18.8% lithium by mass in second sample

Explanation:

Both the two samples are pure lithium carbonate. So % lithium by mass will be same in both samples. This can be proved mathematically as follows-

Let's assume weight of first sample is x g

So, 100 g of sample contains 18.8 g of lithium

Hence, x g of sample contains $(\frac{18.8}{100}\times x)$ g of lithium

Now, the second sample has weight equal to 2x g

So, 2x g of sample contains $(\frac{18.8}{100}\times 2x)$ g of lithium

So, % lithium by mass in second sample = $(\frac{\frac{18.8}{100}\times 2x}{2x})\times 100$ % = 18.8%
