<span>when the number of moles Ca = mass of Ca / molar mass of Ca.
and we can get the molar mass of Ca, it is = 40 g/mol
and we have already the mass of Ca (given) = 9.8 g
so, by substitution: the moles Ca = 9.8 g / 40 g/mol
= 0.245 moles</span>
It true because in photosynthesis, you need celluos
Answer:
b) Industrial farming
Explanation:
The term “industrial agriculture” refers to the type of farming which raises and cultivates large numbers of livestock and plants in high-density environments. It uses modern technology to promote faster growth and reduce illness and death rates in livestock, creating food products on a mass scale.
A liquid boils at a temperature at which its vapor pressure is equal to the pressure of the gas above it. The lower the pressure of a gas above a liquid, the lower the temperature at which the liquid will boil. Boiling point represents a phase change of matter. So no, the boiling poibt of a liquid does not depend on the amount of liquid
