Calcium carbonate, CaCO3 (also called calcite), is the principal mineral found in limestone, marble, chalk, pearls, and the shells of marine animals such as clams. A certain sample of calcium carbonate contain 4.86 moles. What is the mass in grams of this sample?

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?

Ill give u brainliest pls how is mass of carbon conserved during cellular respiration

What conclusion can you draw from this experiment about the components of the black ink?
