Answer:
molecular formula = MgSO4.7H2O
Name is Magnesium sulfate heptahydrate
Explanation:
A hydrate of magnesium sulfate has a mass of 13.52 g. This sample is heated until no water remains. The MgSO4 anhydrate has a mass of 6.60 g. Find the formula and name of the hydrate.
given
mass 1 = 13.52 g
mass 2 = 6.60 g
solution
MgSO4 × H2O
first we ge here mass of hydrate part that is here
mass of hydrate part = (13.52 g - 6.60 g)
mass of hydrate part = 6.92 g
and
now we get here percentage of hydrate that is
percentage of hydrate = (6.92 / 13.52) x 100
percentage of hydrate = 51.18 %
so molar mass will be
molar mass of hydrate MgSO4 = 120.366 g/mol = 49.82 %
and for 100% = 241.6 g
so
mass of H2O = 121.23 g
and
moles of H2O = 7
so we can say that molecular formula will be MgSO4.7H2O
and name is Magnesium sulfate heptahydrate
Answer:
Higher pressure, is the right answer.
Explanation:
The A will have a higher pressure. Since we have given the volume and temperature is same in both containers A and B. Below is the calculation for proof that shows which container has the higher pressure while keeping the volume and temperature the same.
Therefore, the container “A” will have higher pressure.
1) Sexually
2) A mature haploid male germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
3) In a placental mammal, an ovum Is fertilized in a fallopian tube through which it travels into the uterus.
Answer:
Rain
Explanation:
Clouds are formed from water vapor, which turns into ice when the temperature is below freezing, and falls as liquid rain water when temperatures are above freezing. Since the temperatures in the clouds and in the air are above freezing, rain will fall in Florida.
