Which two solutions have similar solubilities at 40°C? Na2SO4 and NaCl Na2HAsO4 and NaCl Na2HAsO4 and Na2SO4 Ba(NO3)2 and Ce2(SO
4)3 • 9H2O
2 answers:
The correct answer is option C i.e. <span>Na2HAsO4 and Na2SO4 Ba(NO3)2
Refer to the graph attached</span><span> below which shows how the solubility of a mixture changes with temperature variation.
As you can see in the graph at 40 </span>°C, both Na2HAsO4 and Na2SO4 Ba(NO3)2 have same solubility coefficients. Thus, the answer is Na2HAsO4 and Na2SO4 Ba(NO3)2

Answer:
The correct answer is (b)
Explanation:
Charles law describes the behavior of gases when heated. Charles law states that the volume of a given mass of gas would increase as its Kelvin temperature increases provided the pressure is held constant. That is the volume of a given mass of gas is directly proportional to its Kelvin temperature at constant pressure
Answer: There are of gas are in a container with a volume of 9.55 mL at 35 °C and a pressure of 895 mmHg
Explanation:
According to ideal gas equation:
P = pressure of gas = 895 mm Hg= 1.18 atm (760 mm Hg= 1 atm)
V = Volume of gas = 9.55 ml = 0.00955 L (1 L=1000ml)
n = number of moles = ?
R = gas constant =
T =temperature =
Thus there are of gas are in a container with a volume of 9.55 mL at 35 °C and a pressure of 895 mmHg
