Answer:

OB) 1.0 atm

Explanation:

we have a mixture of hydrogen, nitrogen and methane and we have the following data

P_t= 3.0 atm

P_H=0.5atm\\P_{CH_4}=1.5 atm\\P_N=?

According to the law of Dalton the sum of the partial pressures of each gas is equal to the total pressure

Total pressure equation

P_t=P_H+P_{CH_4}+P_N

now we clear the partial pressure of nitrogen from the equation

P_t=P_H+P_{CH_4}+P_N\\P_t-P_H-P_{CH_4}=P_N\\3amt-0.5atm-1.5atm=P_N\\1atm=P_N

the partial pressure of nitrogen is 1 atm

the correct answer is OB) 1.0 atm

Answer:

1 Atm

Explanation:

Dalton's law

The total pressure is 3 Atm so all you have to do is subtract the other partial pressures from 3

Use the following table to answer the question. Strong acids Weak acids Weak bases Strong bases HBr CH3COOH NH3 NaOH HCl HF NH4O
Y_Kistochka [10]

Answer: The salt which has the highest pH is CH_3COONa

Explanation: Salts are formed by the reaction of acid and base. General equation for the generation of salt is given by:

HX+BOH\rightarrow BX+H_2O

The given salts are formed from the reaction of acids and bases.

1) K_2SO_4

This is a salt formed by the reaction of strong base (KOH) and strong acid (H_2SO_4) . So, this salt is a neutral salt.

H_2SO_4+2KOH\rightarrow K_2SO_4+2H_2O

2) CuSO_4

This is a salt which is formed by the reaction of weak base (Cu(OH)_2) and strong acid (H_2SO_4). So, this salt is an acidic salt.

H_2SO_4+Cu(OH)_2\rightarrow CuSO_4+2H_2O

3) NH_4Cl

This is a salt which is formed by the reaction of weak base (NH_3) and strong acid (HCl). So, this salt is an acidic salt.

HCl+NH_3\rightarrow NH_4Cl

4) CH_3COONa

This is a salt which is formed by the reaction of  strong base (NaOH) and weak acid (CH_3COOH). So, this salt is a basic salt.

CH_3COOH+NaOH\rightarrow CH_3COONa+H_2O

Now, we have to find the salt which has the highest pH value.

Highest pH value means that the salt must be basic in nature and from the given salts, only CH_3COONa is basic salt. Hence, this salt has the highest pH value.

A sample of argon (Ar) gas has a volume of 7.31 L at a pressure of
Pie

Answer:

17.1 L

Explanation:

P1V1/T1  =  P2V2/T2        T is in K

P1V1/T1 * T2/P2 = V2

735 * 7.31 / (45+273.15)  * (55+ 273.15)/325 = V2

V2 = 17.1 L
