A solution of CaCl2 in water forms a mixture that is 32.0% calcium chloride by mass. If the total mass of the mixture is 645.4 g, what masses of CaCl2 and water were used

Balance this equation: n2 + h2 > nh3, write the following molar ratios: n2 / n2 / nh3 h2 /

Will mark brainliest how many electrons can be held in the energy level n = 4?

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
