GREYUIT [131]3 years ago
4 0

The question is incomplete; the complete question is;

Why will the conjugate base of a weak acid affect pH? Select the correct answer below: O it will react with hydroxide

O it will react with water

O it will react with hydronium

O none of the above Content attribution

Answer:

O it will react with hydronium

Explanation:

If we have a weak acid HA, the weak acid ionizes as follows;

HA(aq) ----> H^+(aq) + A^-(aq)

A^- is the conjugate base of the weak acid.

H^+ interacts with water to form the hydronium ion as follows;

H^+(aq) + H2O(l) ----> H3O^+(aq)

The pH=[H3O^+]

But the conjugate base of the weak acid reacts with this hydronium ion thereby affecting its concentration and the pH of the system as follows;

A^-(aq) + H3O^+(aq) ------> HA(aq) + H2O(l)

Calculate the molarity of a solution if there are 1.5 mol of NaCl in 2.3 L of solution
frosja888 [35]

Answer:

0.6522 mol/L.

Explanation:

<em>Molarity is defined as the no. of moles of a solute per 1.0 L of the solution.</em>

<em />

M = (no. of moles of solute)/(V of the solution (L)).

<em>∴ M = (no. of moles of solute)/(V of the solution (L)) </em>= (1.5 mol)/(2.3 L) = <em>0.6522 mol/L.</em>

Carbordum is silicon carbide SiC a very hard material used as an abrasive on sand paper and in other applications. it is prepare
AleksandrR [38]

Answer:

4.5 kilograms of silicon dioxide is required to produce 3.00 kg of SiC.

Explanation:

The balanced equation for the reaction between silicon dioxide and carbon at high temperature is given as:

SiO_2+3C\rightarrow SiC+2CO

1 mole silicon dioxide reacts with 3 moles of carbon to give 1 moles of silicon carbide and 2 moles of carbon monoxide.

Mass of SiC = 3.00kg = 3000.00 g

1 kg = 1000 g

Molecular mass of SiC = 40 g/mol

Moles of SiC = \frac{3000.00 g}{40 g/mol}= 75 mol

According to reaction, 1 mole of SiC is produced from 1 mole of silicon dioxide.

Then 75 moles of SiC will be produce from:

\frac{1}{1}\times 75 mol=75 mol of silicon dioxide.

mass of 75 moles of silicon dioxde:

75 mol\times 60 g/mol=4500 g=4.5 kg

4.5 kilograms of silicon dioxide is required to produce 3.00 kg of SiC.
