Explanation:

Balance Chemical Equation:

A balanced chemical equation is that in which the number of the reactant atoms equal to the number of the product atom.

For example if the oxygen at the reactant side is 4, the number of oxygen must be 4 on the product side.

Solution

1. Au₂S₃ + H₂ --------> Au + H₂S

Balance Chemical Equation

1 Au₂S₃ + 3 H₂ --------> 2 Au + 3 H₂S

2. FeS + O₂ ---------> Fe₂O₃ + SO₂

Balance Chemical Equation

4FeS + 7O₂ ---------> 2Fe₂O₃ + 4SO₂

3. NH₃ + O₂ ---------> NO + H₂O

Balance Chemical Equation

4 NH₃ + 5 O₂ ---------> 4 NO + 6 H₂O

4. BaO + H₂O --------> Ba(OH)₂

Balance Chemical Equation

1 BaO + 1 H₂O --------> 1 Ba(OH)₂

Now by balancing all the atoms in equation are equal in reactant and product

wanahton purified a portion of water with 900 grams of contaminants. each hour, a third of the contaminants was filtered out.

let g(n) be the amount of contaminants (in grams) that remained by the beginning of the nth hour. g is a sequence, what kind of sequence is it, arithmetic or geometric? then, write an explicit formula for the sequence, g(n)=
