Answer:

Explanation:
The chemical equation of the reaction is as follows
According to the question, data provided in the question is shown below:

The C = Carbon and its standard state is Graphite C(s)
The H = Hydrogen and its standard state is
(s)
The O = Oxygen and its standard state is
(s)
Now the chemical equation for the reaction is

20 g is the answer to make it a saturated solution
Answer:
108.9g of Silver can be produced from 125g of Ag2S
Explanation:
The compound Ag2S shows that two atoms of Silver Ag, combined with an atom of Sulphur S to form Ag2S. We can as well say the combination ration of Silver to Sulphur is 2:1
•Now we need to calculate the molecular weight of this compound by summing up the molar masses of each element in the compound.
•Molar mass of Silver Ag= 107.9g/mol
•Molar mass of Sulphur S= 32g/mol
•Molecular weight of Ag2S= (2×107.9g/mol) + 32g/mol
•Molecular weight of Ag2S= 215.8g/mol + 32g/mol= 247.8g/mol
•From our calculations, we know that 215.8g/mol of Ag is present in 247.8g/mol of Ag2S
If 247.8g Ag2S produced 215.8g Ag
125g Ag2S will produce xg Ag
cross multiplying we have
xg= 215.8g × 125g / 247.8g
xg= 26975g/247.8
xg= 108.85g
Therefore, 108.9g of Silver can be produced from 125g of Ag2S
Answer:
True
Explanation:
A synthesis reaction is one that involves the combination of more than one reactants to form a single product. This is directly opposite to a decomposition reaction where a complex compound is broken down into various products.
Examples of synthesis reaction are;
1. The combination of sodium with chlorine to form sodium chloride.
2. The combination of hydrogen and oxygen to form water
so explaining what Brianna did, the models of clay are the reactants coming together to form a single product which is the sculpture.
