Answer:In the chemical formula Al2(SO4)3, the Al2 means there two aluminium (atoms or ions). The SO4 is a sulfate ion and (SO4)3 means there are 3 sulfate ions. The number 3 before Al2(SO4)3 means there are three times the number of atoms and ions of the chemical formula.
When you drive your car, you use the gasoline to produce energy which exerts the oil thay was put into the car, would then from it into a cloud or puff of gas which pollutes the air, rises through the atmosphere, and eats away at the Ozone Layer.
Idk if it's correct but I guess it's calcite (c)
Explanation:
Metabollic rate is the amount of energy expended from an organism at a given point in time.
Equation of how glucose (food) is broken down via respiration:
C6H12O6(s) + 6O2(g) --> 6H2O(l) + 6CO2(g)
The amount of energy produced for the types of food is roughly proportional to the amount of oxygen use, so that the metabolic rate can be measured by measuring the rate of oxygen consumption.
