Answer:
120G
Explanation:
From the combustion process, about 120G of carbon dioxide would be released into the atmosphere.
For the chemical reaction to obey the law of conservation of matter, if only ash and carbon dioxide are the product, then the sum of the mass of the product and that of the reactants must be the same.
In a chemical reaction, matter is not created nor destroyed, but they are simply changed from one form to another.
Mass of wood burning = mass of ash + mass of CO₂
150G = 30G + mass of CO₂
mass of CO₂ = 150G - 30G = 120G
Answer: 14.01 moles
To solve this question, you need to determine the molecular mass of the Ba(OH)2. The molecular mass would be: 137.3 + 2(16+1)= 171.3g/mol.
If the total weight of Ba(OH)2 is 2400g and its molecular mass is 171.3g/mol, the number of moles would be: 2400g/ (171.3g/mol)=14.01 moles

Explanation:
The mass of a salt in grams that will dissolve in 100 mL of water.--- solubility
A solution that has dissolved the maximum amount of a compound at a given temperature.---- saturated solution
Any further addition of salt will remain undissolved-----supersaturated solution
The maximum number of moles of a salt that will dissolve in 1 L of solution----molarity
A decrease in the solubility of an ionic compound as a result of the addition of a common ion..... Common ion effect
The product of the molarities of the dissolved ions, raised to a power equal to the ion's coefficient in the balanced chemical equation........solubility product.
