Answer:
The correct answer is - at high pressure a huge amount of gases can be stored in less volume.
Explanation:
We already know that pressure is inversely proportional to the volume of gas which means if we increase the pressure the volume of gas becomes less.
P = 1/V
So in the scuba divers tank, the oxygen is filled at very high pressure so the high amount of the oxygen can be filled in less volume and which will last for longer than a normal pressure tank can last.
<span>Nitrogen gas is converted to nitrate compounds by nitrogen-fixing bacteria in soil turns nitrogen gas into root nodules. Nitrogen is the most commonly limiting nutrient in plants. Legumes use nitrogen fixing bacteria, specifically symbiotic rhizobia bacteria, within their root nodules to counter the limitation.</span>

Answer:</h3>
Molarity of solution X is 0.1 M
Molarity of solution Y is 0.05 M
<h3>
Explanation:</h3>
- Dilution involves addition of more solvent to a solution resulting to a decrease in concentration.
- Solution X is made by taking 10 mL of a 1.0 M and adding water to make a total volume of a 100 mL.
- Using dilution equation we can determine the Molarity of solution x.
- Dilution equation is given by, M₁V₁ = M₂V₂, where M₁ and M₂ are the initial and diluted solution concentrations while V₁ and V₂ are the start and the final volume respectively.
Therefore;
M₂ = M₁V₁ ÷ V₂
= (1.0 M × 0.01 L) ÷ 0.1 L
= 0.1 M
Thus, the concentration of solution X is 0.1 M
- On the other hand, solution Y is made by using 5 mL of solution X and diluting it again by adding it to 95 mL
- Therefore, using dilution equation we can find the molarity of solution Y
M₁V₁ = M₂V₂
M₁ = 0.1 M (molarity of solution X)
V = 5 mL
V₂ = 5 mL + 95 mL
= 100 mL
Thus, M₂= M₁V₁ ÷ V₂
= (0.1 M × 0.005 L) ÷ 0.01 L
= 0.05 M
Therefore, the molarity of solution Y is 0.05 M
Hello there!
Aspartame has 4 kilocalories of energy per gram and table sugar has 3.9 kilocalories. They are pretty much same but aspartame is 200 times sweeter than sucrose so probably would be aspartame that has more calories.
