Calculate the maximum mass of carbon dioxide that could be obtained by adding excess hydrochloric acid
to 15 g of calcium carbonate.
CaCO3 + 2HCI — CaCl2 + H2O + CO2

6.6 g

Explanation:

The mole ration between CaCO₃and CO₂ is 1 : 1

Because the molar mass of CaCO₃ is 100.0869 g/mol the amount of moles used in this chemical reaction is;

15/ 100

This will be similar to the moles of CO₂

Because the molar mass of CO₂ is 44g, then well multiply by the moles;

15/100 * 44

= 6.6 g

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

answer: they produce more slow than unicellular organisms.
