Answer:
447,25k
Explanation:
According to the ideal gas law
Where:
P: is the pressure of the gas in atmospheres.
V: is the volume of the gas in liters.
n: number of moles of the gas
R: ideal gas constant
T: absolute temperature of the gas in kelvin
now using:
Calcium chloride dehydrate (CaCl₂ · 2 H₂O) have a molar mass equal to 147 g/mol.
Explanation:
To calculate the molar mass of calcium chloride dehydrate (CaCl₂ · 2 H₂O) we use the following formula:
molar mass of CaCl₂ · 2 H₂O = atomic weight of Ca × 1 + atomic weight of Cl × 2 + atomic weight of H × 4 + atomic weight of O × 2
molar mass of CaCl₂ · 2 H₂O = 40 × 1 + 35.5 × 2 + 1 × 4 + 16 × 2
molar mass of CaCl₂ · 2 H₂O = 147 g/mol

Answer: Chemical change
Explanation:
Physical change is a change where there is a change in size , shape etc and no new products are formed.
Chemical change is a change where there is a change in chemical composition as new products are formed.
Example: Formation of soap and glycerin from fat and sodium hydroxide is a chemical change as the chemical bonds are getting rearranged to form new products.
Answer:
Fixed
Explanation:
A solid is the substance that have fixed shape and size. For example: Ice,Wood etc. They have a fixed shape and volume.
