Answer:
The respiratory system is the network of organs and tissues that help you breathe. basically your airways, lungs, and blood vessels so you quite literally need these to survive I mean your muscles need oxygen to function and your brain needs oxygen to function so without your respiratory system you wouldn't be able to move much and you would quickly pass out and die from the lack of oxygen to your brain there are other body processes that need oxygen as well but these are just two examples.

(PLEASE HELP) 500 mL of a gas is collected at 745 mmHg. What will the volume be at 1.8 atm?
Answers
Answer:
272.22 mLExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the new volume we have
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
First convert 745 mmHg to atm
760 mmHg = 1 atm
745 mmHg = 745/760 = 0.98 atm
We have
[tex]V_2 = \frac{500 \times 0.98}{1.8} \\ = 272.222...[/tex]
We have the final answer as
272.22 mLHope this helps you
Given the following equation: Na2O + H2O ---> 2 NaOH
How many moles of NaOH are produced from 1.02 moles of Na2O?
Answers
Answer:
2.04 moles
Explanation:
Since the ratio of Na2O to NaOH is 1:2, you multiply the number of moles by 2, equaling 2.04 moles.
