Answer:
1.47 mol/L
Explanation:
Molarity is given as,
Molarity = Moles / Vol in L ------- (1)
Moles of CaCl₂,
Moles = Mass / M.Mass
Moles = 535 g / 110.98 g/mol
Moles = 4.82 mol
Now, putting values in eq. 1.
Molarity = 4.82 mol / 3.28 L
Molarity = 1.47 mol/L
Answer: a. 
: 
is negative
b. 
: is negative
c. 
: is negative
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa
a)
In this reaction 2 moles of gaseous reactants are converting to 1 mole of gaseous products. The randomness will decrease and hence entropy will also decrease. Thus is negative.
b)
In this reaction solid reactants are converting to aqueous products. The randomness will increase and hence entropy will also increase. Thus is positive.
c)
In this reaction aqueous reactants are converting to solid products. The randomness will decrease and hence entropy will also decrease. Thus is negative
Answer:
the lithosphere is broken into sections called plates.
To calculate the actual heat, I'd use calorimetric to weigh a sample mass. I 'd calculate the mass of a material sample. At a specified temperature, I will heat the material. I should position the heated material inside a calorimeter for coffee cup containing an initially established mass of water. I 'd wait for the weather to stabilize and then measure the difference in weather. To assess the sum of energy consumed, I will use the increase in water temperatures. For measure real heat I will use the sum of energy per material, weight, and temperature shift.
