Answer:
The balanced chemical equation will be "
".
Explanation:
The given equation is:

<u>Step 1:</u>
<u></u>
...(equation 1)
<u>Step 2:</u>
<u></u>
...(equation 2)
On adding "equation 1" and "equation 2", we get
⇒ 
⇒ 
The second step:
⇒ 
The answer should be 479 i could possibly be wrong but that’s what i got because one mole is 47.90 grams
Answer:
There is 5.56 g of gold for every 1 g of chlorine
Explanation:
The ratio is the relationship between two numbers, defined as the ratio of one number to the other. So, the ratio between two numbers a and b is the fraction 
You know that a compound has 15.39 g of gold for every 2.77 g of chlorine. This can be expressed by the ratio:

The proportion is the equal relationship that exists between two reasons and is represented by: 
This reads a is a b as c is a d.
To calculate the amount of gold per 1 g of chlorine, the following proportion is expressed:

Solving for the mass of gold gives:

mass of gold= 5.56 grams
So, <u><em>there is 5.56 g of gold for every 1 g of chlorine</em></u>
