Answer:

A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. At the same concentration, weak acids have a higher pH value than strong acids.

Answer:

200 grams is the mass of 15% of the solution of lime that is formed by dissolving 30g of calcium hydroxide in water.

Explanation:

Mass of solution = M

Mass percentage of the solution of lime = 15%

Mass of lime or calcium hydroxide = m = 30 g

The Formula of mass percentage is given as :

$m/m\%=\frac{m}{M}\times 100$

On substituting the values in ab above formula :

$15\%=\frac{30 g}{M}\times 100$

$M=\frac{30 g}{15}\times 100=200 g$

200 grams is the mass of 15% of the solution of lime that is formed by dissolving 30g of calcium hydroxide in water.

BrainlieSTTTTTT A gas is originally stored at a pressure of 25 atm with a volume of 3 L. If the pressure were increased to 75 at

Crazy boy [7]

Explanation:

Apply Boyle's Law :-

P1V1 = P2V2

Where P1 is 25 atm
V1 is 3L
P2 is 75 atm
V2 is what we need to find out.

25 × 3 = 75 × V2

$\tt{V_2 = \dfrac{ 25 \times 3}{75}}$

$\tt{V_2 = \dfrac{75}{75}}$

<u>So, the answer is d) Part, 1L .</u>

Hope it helps :)
