Limestone (CaCO3) is decomposed by heating to quicklime (CaO) and carbon dioxide. Calculate how many grams of quicklime can be p
Harman [31]

Answer: 2800 g

Explanation:

CaCO_3(s)\rightarrow CaO(s)+CO_2(g)

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Given mass = 5 kg = 5000 g

\text{Number of moles}=\frac{5000g}{100g/mol}=50moles

1 mole of CaCO_3 produces = 1 mole of CaO

50 moles of CaCO_3 produces =\frac{1}{1}\times 50=50moles of CaO

Mass of CaO=moles\times {\text{Molar mass}}=50moles\times 56g/mole=2800g

2800 g of CaO is produced from 5.0 kg of limestone.

In what specific situations would you use a light microscope? an electron<br>microscope?​
galina1969 [7]

ANSWER

A standard light microscope is used to view living organisms with little contrast to distinguish them from the background, which would be harder to see with the electron microscope.

Electron microscopes can be used to examine not just whole cells, but also the subcellular structures and compartments within them.
