Assume you have 100 g of the compound so you have 87.5 g N and 12.5 H and divide by their molar masses.

87.5 g N / <span>14.0067</span> g (molar mass) = ~6.25 moles

12.5 g H / 1.008 = ~2.4 moles

Empirical Formula = N6H12

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.

What type of chest tube system does this statement describe?
Komok [63]

Answer:

<em>Dry suction chest tube system</em>

Explanation:

<em>The dry suction drains that are self-regulating today use a small, adjustable regulator installed into the drain. </em>

So long as there is enough air flow from the suction of the wall (that will be shown on the drain) it will respond correctly to changes in the pressure of the source or the patient to retain suction at the drain level.

It's also a quiet mode of activity.
