The answer to your question is winter
Answer:
The mass of water formed is 38 grams
Explanation:
Answer:
We cannot use hydrogen peroxides and chlorine bleach as a natural indicators because they are dissociated into its ions and changes their pH of dissociation.
Explanation:
Natural indicators are organic material that they formed by natural tissues and these are cannot be broken down into the further ions. Hence the pH value is cannot be vary.
If we use hydrogen peroxide and chlorine beach as as natural indicators these are further broken down into its ions and change their pH of dissociation.
Hence, we cannot used as a natural indicators.
0.590 mol of calcium carbonate are in 63.8 g of calcium carbonate.
<u>Explanation:</u>
Chemical substances are framed with respect of their molar quantity, as these are molar ratios, not mass, that occur in stoichiometrically balanced equations. We divide mass by the molar mass of a single molecule or unit of formula to extract moles from mass.
In order to start calculation, firstly the molar mass of calcium carbonate is needed to be detected as follows:
The molar mass of calcium = 40.08 g/mol, carbon is = 12.01 g/mol while for oxygen = 16.00 g/mol.
Thus adding above quantities to calculate molar mass of calcium carbonate: 40.08 + 12.01 + 3(16.00) = 108.09 g/mol.
Now by dividing the mass of calcium carbonate to its molar mass:
63.8g / 108.09 g/mol = 0.590 mol of calcium carbonate.
