Answer:
The component that dissolves the other component is called the solvent. Solute – The component that is dissolved in the solvent is called solute
Answer: The amount of carbon-14 left after 10 years is 25 g
Explanation:
Formula used :
where,
a = amount of reactant left after n-half lives = ?
= Initial amount of the reactant = 100 g
n = number of half lives =
Putting values in above equation, we get:
Therefore, the amount of carbon-14 left after 10 years is 25 g
Answer:

Cobalt Silicate can serve as a semi-conductor.
Answer:
For oxygen: mass % O = (mass of 1 mol of oxygen/mass of 1 mol of CO2) x 100. mass % O = (32.00 g / 44.01 g) x 100. mass % O = 72.71 %
