What maximum fraction of the air in the room could be displaced by the gaseous nitrogen?

Chemistry
1 answer:
bulgar [2K]3 years ago
6 0
The atmosphere is made up of different gases. The air in any room can be likened to the air outside and so the same proportions of gases would apply. The air surrounding the earth is composed of 78% nitrogen, 21% oxygen, 1% argon and trace amounts of other gases including carbon dioxide. These values indicate therefore that the maximum fraction to be displaced is 78%.

How do neutral metal atoms form ions?​
stira [4]

Answer:

Neutral atoms can be turned into positively charged ions by removing one or more electrons. ... Atoms that gain extra electrons become negatively charged. A neutral chlorine atom, for example, contains 17 protons and 17 electrons. By adding one more electron we get a negatively charged Cl- ion with a net charge of -1.

You’ve just started a new job in the laboratory of the Food and Drug Administration. Your supervisor asks you to prepare a 1.50-
anastassius [24]

Answer:  118.5 grams

Explanation:

Molarity is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n\times 1000}{V_s}

where,

n= moles of solute

V_s = volume of solution in ml = 500 ml

1.50=\frac{moles\times 1000}{500ml}

moles = 0.75

moles of solute =\frac{\text {given mass}}{\text {molar mass}}

0.75 =\frac{\text {given mass}}{158g/mol}

mass of KMnO_4 = 118.5 grams

Thus mass of KMnO_4 needed to prepare 500 mL of this solution iis 118.5 grams
