One of the main components of pearls is calcium carbonate (caco3). if pearls are put into an acidic solution, they dissolve: caco3(s) + 2hcl(aq) ➡ cacl2(aq) + h2o(l) + co2(g). how many moles of caco3 can be dissolved in 0.0250 moles of hydrochloric acid?

0.0125 moles

0.0500 moles

2.50 moles

4.50 moles

Answer : The correct option is, 0.0125 moles

Explanation : Given,

Moles of HCl = 0.0250 mole

The given balanced chemical reaction is :

From the balanced chemical reaction, we conclude that

As, 2 moles of HCl react with 1 mole of

So, 0.0250 moles of HCl react with of

Therefore, the number of moles of dissolved will be, 0.0125 mole

c. 75.7

i think that is the right

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
