Answer:
C. Sold solution
Explanation:
Using method of elimination;
A. Pure substance.
Bronze is not a Pure substance because the proportions of copper and tin are not the same in all bronze. This option is wrong.
B. Colloidal Suspension
This option is wrong. Colloidal suspension involves one substance dispersed in another.
C. Sold solution
The bronze bell is an alloy. This definition suitable represents it. It is a solid solution containing copper and tin. This is the correct option.
D. Heterogeneous Mixture
Bronze is a mixture, however it is homogeneous and not heterogeneous. his is because one can not distinguish the copper from the tin in the mixture.

Answer:
The pressure of the gas is 0.278 atm
Explanation:
Step 1: Data given
Number of moles of the ideal gas = 0.540 moles
Volume = 35.5 L
Temperature = 223 K
Step 2: Calculate the pressure of the gas
p*V = n*R*T
⇒with p = the pressure of the gas = TO BE DETERMINED
⇒with V= the volume of the gas = 35.5 L
⇒with n = the moles of the gas = 0.540 moles
⇒with R = the gas constant = 0.08206 L*atm/mol*K
⇒with T = the temperature of the gas = 223 K
p = n*R*T / V
p = 0.540 * 0.08206 * 223 / 35.5
p = 0.278 atm
The pressure of the gas is 0.278 atm
Answer:
All strong acids have a higher value of and the equilibrium for the reaction with water lies far to the right.
Explanation:
All strong acids dissociate completely in the solution. Higher the value of dissociation constant of the acid, higher will be the dissociation of the acid.
The reaction of the acid with water will be favored in the forward direction for acids having higher dissociation constant value ().
The dissociation of a strong acid say HA in water is shown below
Higher the value of , more will be the dissociation of the acid in water. The reaction will move far to the right side.
