Hey there!

AlCl₃ + NaOH → Al(OH)₃ + NaCl

Balance OH.

1 on the left, 3 on the right. Add a coefficient of 3 in front of NaOH.

AlCl₃ + 3NaOH → Al(OH)₃ + NaCl

Balance Cl.

3 on the left, 1 on the right. Add a coefficient of 3 in front of NaCl.

AlCl₃ + 3NaOH → Al(OH)₃ + 3NaCl

Balance Na.

3 on the left, 3 on the right. Already balanced.

Balance Al.

1 on the left, 1 on the right. Already balanced.

Our final balanced equation: AlCl₃ + 3NaOH → Al(OH)₃ + 3NaCl

Hope this helps!

Pressure has the most influence on the solubility of which type of solute?

Scilla [17]

I think that pressure will affect the solubility of gasses the most. The reason why I think this is that gasses are affected the most by pressure change. By definition solids and liquids are not easily affected by pressure by how close the molecules are to each other in both of those phases.

I hope this helps. Please let me know if you have any further questions or need any clarification.

Hydrochloric acid reacts faster with powdered zinc than with an equal mass of zinc strips because the greater the surface area o

inysia [295]

Answer:

increases the frequency of particle collisions

Explanation:

One factor upon which the rate of reaction depends is the surface area of reactants.

According to the collision theory, reactions occur when reactant particles having the required (activation) energy collide with each other, this collision is inelastic. However, collision of particles having energies less than the activation energy results in elastic collisions and no chemical reaction.

The more the exposed surface area of reactants, the greater the number of particles that come into contact with each other and the more the chances of frequent effective collisions that lead to reaction.

Thus, powdered zinc reacts faster with hydrochloric acid than zinc strips

Answer:

1.7 Osm/L

Explanation:

Osmotic concentration is the number of osmoles (Osm) of solute per litre of solution .

$\text{Osmotic concentration} = \dfrac{\text{No. of osmoles }}{\text{Litres of solution}}$

An osmole is the number of moles of solute that contribute to the osmotic pressure of a solution.

1 Osm = i × n, where

i = the van't Hoff i factor and

n = the number of moles

The van't Hoff i factor is the number of solute particles obtained from 1 mol of solute.

For example,

MgSO₄(aq) ⟶ Mg²⁺(aq) + SO₄²⁻(aq)

1 mol of MgSO₄ produces 2 mol of ions in solution, so i = 2.

$\text{Osmotic concentration} = \dfrac{\text{1.0 Osm}}{\text{0.6 L}} = \textbf{1.7 Osmol/L}$

A student determines the molar mass of acetone

love history [14]

The Formula of Acetone is $C_3H_6O$
To find the Mass Molar of a compound, you add the Atomic weights of it's atoms.
If you check the Periodic table:
Atomic Weight of Carbone C: 12.0107
Atomic Weight of Hydrogen: 1.00794
Atomic Weight of Oxygen: 15.9994

So, you got:
Total Atomic Weight of Carbone in Acetone: 12.0107 * 3 = 36.0321
Total Atomic Weight of Hydrogen in Acetone: 1.00794 * 6 = 6.04764
Total Atomic Weight of Oxygen in Acetone = 15.9994 * 1 = 15.9994

Now, you add this numbers
36.0321 + 6.04764 + 15.9994 = 58.07914

So, the Molar Mass of Acetone is 58.09714 g/mol

Hope this Helps :D
