You should read up on Proust's law, better known as the Law of Definite Proportions. This is a chemical law that defines your question more generally, on why the ratio of elements and ions are always fixed.

Basically, this compound Magnesium(II) Chloride is MgCl2 because it has the same number of protons, neutrons, and electrons all the way. This defines the properties of the compound or atom.

How many moles of C2H2 are needed to react completely with 84.0 mol O2?
Mama L [17]
The reaction between C2H2 and O2 is as follows:
2C2H2 + 5O2 = 4CO2 + 2H2O

After balancing the equation, the reaction ratio between C2H2 and O2 is 2:5.

The moles of O2 in this reaction is 84.0 mol. According to the above ratio, the moles of C2H2 needed to react completely with the O2 is 84.0mole *2/5 = 33.6 mole.

Alex17521 [72]

Answer:

The answer to your question is 25 grams

Explanation:

Data

half-life = 5730 years

sample = 200 g

after 3 half-lives

Process

Calculate the amount of sample after one, two and three half-lives.

After each half-life, that of sample is half the previous amount.

                         Number of half-lives           Amount of sample

                                       0                                        200 g

                                        1                                         100 g

                                        2                                          50 g

                                       3                                           25 g
