A strong electrolyte dissociates completely into its ions but in weak electrolyte only certain number of ions are dissociated so pH depends upon the dissociated ions.

Definition of pH

An evaluation of how basic a substance or solution is its pH is determined. pH is measured on a scale from 0 to 14. A pH value of 7 is considered to be neutral on this scale, which implies it is neither acidic nor basic. If the pH value is less than 7, it is considered to be acidic and if the pH value is greater than 7, it is considered to be basic.

pH < 7 for NH₃ and HClO₄ since the acid is strong acid and the base is weak base.

The pH value for NaOH and Benzoic acid is pH > 7, since the base is strong base and acid is a weak acid .

pH = 7 for HBr and KOH since both are strong acid and strong base

pH < 7 or pH > 7 since both are neutral.

Gas is heated from 480. K to 750. K and the pressure is kept constant, what final volume would result if the original volume was
attashe74 [19]
Charles law gives the relationship between volume and temperature of gas.
It states that at constant pressure volume is directly proportional to temperature
Therefore
V/ T = k
Where V - volume T - temperature in kelvin and k - constant
V1/T1 = V2/T2
Parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
Substituting the values in the equation
267 L/ 480 K = V / 750 K
V = 417 L
Final volume is 417 L

Answer:

The correct answer is A) circulatory

Explanation:

The circulatory system collects metabolic wastes from the blood, which will be eliminated by the kidneys through urine.

The kidneys are responsible for the elimination of waste, acids and excess fluid from the body, maintaining the balance of water, salts and minerals. Blood flows into the kidney through the renal artery.
