What is the chemical formula for the perchlorate ion? ClO_2^- ClO_3^- ClO_4^- ClO^- What is the mass of silver chlorate (191.32 g/mol) that decomposes to release 0.466L of oxygen gas at STP? 2 AgClO_3 (s) 2 AgCl(s) + 3 O_2 (g) 5.97 g 7.96 g 1.33 g 2.65 g 3.98 g Acetic acid is a weak acid, potassium hydroxide is a strong base, and potassium acetate is a soluble salt. Which of the following is the net ionic equation for the reaction? HC_2 H_3 O_2(aq) + KOH_(aq) rightarrow KC_2 H_3 O_2_(aq) + H_2 O (g) H^+ (aq) + OH^- (aq) rightarrow H_2 O(g) C_2 H_3 O_2^- (aq) + K^+ (aq) rightarrow KC_2 H_3 O_2 (aq) H^+ (aq) + KOH_(aq_ rightarrow K^+ (aq) + H_2 O(g) HC_2 H_3 O_2 (aq) + OH^- (aq) rightarrow C_2 H_3 O_2^- (aq) + H_2 O(g) A sample of ammonia gas occupies 200 mL at 585 torr and 20.0 degree C. If the volume of the gas is 50.0 mL at 50.0 degree C what is the pressure? 585 torr 1330 torr 212 torr 258 torr 1610 torr Which of the following can be separated into two or more pure substances using a physical compound element mixture all of the above

Explanation / Answer

24. Molar mass of CO2 is 44 g/mol

Molar mass of CO is 28 g/mol

Molar mass of N2O4 is 92 g/mol

Molar mass of SO3 is 80

According to Grahm's law if the molar mass of the gas is less then that gas will have more rate of effusion.

Among the given gases CO is having less molar mass CO is having more rate of effusion.

Therefore option (b) is correct

25.The formula of perchlorate ion is ClO4-
