Answer:
atoms
Explanation:
atoms combines to form compound
Catastrophism is a theory that stated that earth was shaped by a suddentmassive violent events that happened within a short period of time.
Uniformitarianism, on the other hand, is a theory that stated earth was shaped by slow and gradual events over a long period of time, which could take millions of years.
The molar mass of a substance is the mass of one mole of that substance. Therefore, in order to calculate the mass that is present while the number of moles are known, we simply multiply the number of moles present by the molar mass. In the case of carbon dioxide, the molar mass is obtained by adding the mass of one carbon atom (12) and two oxygen atoms (32). The molar mass is 12 + 32 = 44. Therefore, the mass of carbon dioxide is 2.1 * 44 = 92.4 grams. The answer is D<span>.</span>
Answer is: Reactants: 2VCl2 and 3Cl2; product: 2VCl5.
Balanced chemical reaction: 2VCl₂ + 3Cl₂ → 2VCl₅.
According to principle of mass conservation, number of atoms must be equal on both side of chemical reaction.
There are ten chlorine atoms and two vanadium atoms on both side of balanced chemical reaction.
