From a laboratory process, a student collects 28.0 g of hydrogen and 224.0 g of oxygen. how much water was originally involved i
nikklg [1K]

Chemical reaction is given as :

2H_{2}O\rightarrow 2H_{2}+O_{2}

Here, 2 moles of water gives 2 moles of hydrogen and one mole of oxygen.

Mass of hydrogen =  28.0 g (given)

Mass of oxygen = 224.0 g (given)

Number of moles = \frac{given mass}{molar mass}

Thus, number of moles of hydrogen = \frac{28 g}{2\times 1 g/mol}

= 14 moles of hydrogen

Number of moles of oxygen= \frac{224 g}{2\times 16 g/mol}

= 7 moles of oxygen

Now, to find the amount of water:

7 mol of oxygen \times (\frac{2 mol of water}{1 mol of oxygen})\times (18 g/mol of water)

= 252 g of water.

Thus, amount of water is 252 g (involved in the process).

Which list of phases of H2O is arranged in order of increasing entropy
jarptica [38.1K]
<span>The list of phases of H2O that is arranged in order of increasing entropy is from solid then liquid then gas. Gaseous water has the most entropy because of the random movement of water molecules. And Solid having the least entropy because the water molecules are arranged in a specific order.</span>

andre [41]

Answer:

It would be higher than expected.

Explanation:

Respiration quotient (RQ) may be defined as the quantity used for the representation of the basal metabolic rate. This mainly depends on the amount of the carbon dioxide.

The respiratory quotient represents the ratio of carbon dioxide eliminated with the amount of the oxygen consumed. During stress condition, the oxygen consumption of our body increase and more carbon dioxide is exhale out from the body. This will increase the RQ.

Thus, the answer is RQ will be higher than expected.
