Solution A has a pH of 10, and solution B has a pH of 1. Which statement best describes these solutions?

Free_Kalibri [48]

Answer:

Solution A is a Weak Alkali, Solution B is a strong Acid.

Explanation:

At pH 10, the colour is blue, therefore it's a weak alkali.

At pH 1, the colour is red, therefore it's a strong Acid.

At a pressure of 505 kPa, the volume of a gas is 12.00 mL. Assuming the temperature remains constant,

Sergio [31]

Answer:

757.5 kPa

Explanation:

Boyle's law states that p1 * v1 = p2 * v2

v1 = 12 mL

v2 = 8 mL

p1 = 505 kPA

p2 = ?

(505)(12) = (p2)(8)

6060 = (p2)(8)

p2 = 757.5

How much potassium chloride is needed to make 0.500 m solution with 1.50 L of water?

Andrew [12]

Answer:

55.9 g KCl.

Explanation:

Hello there!

In this case, according to the definition of molality for the 0.500-molar solution, we need to divide the moles of solute (potassium chloride) over the kilograms of solvent as shown below:

$m=\frac{mol}{kilograms}$

Thus, solving for the moles of solute, we obtain:

$mol=m*kilograms$

Since the density of water is 1 kg/L, we obtain the following moles:

$mol=0.500mol/kg*1.50kg\\\\mol=0.75mol$

Next, since the molar mass of KCl is 74.5513 g/mol, the mass would be:

$0.75mol*\frac{74.5513g}{1mol}\\\\55.9g \ KCl$

Regards!
