All reactions have an equilibrium, at which the rate of the reaction rates on each side of the equation are equal to each other. Sometimes that can be one-way, but it’s more often a two-way street. Where you’ll have an amount of products and reactants.
The Earth rotates 365 times during each complete revolution.

we are asked in this problem to determine the mass of a liquid in a small container. In order to determine the mass, we use an analytical balance for greater accuracy by first weighing the whole system (liquid+beaker). Then transfer the liquid to another container and completely dry the beaker (wash and dry). measure the weight of the beaker. The mass of the liquid is equal to the mass of the system minus the mass of the beaker.
Beryllium (Be) and Calcium (Ca)
