Did you know conventional argult culture has increased greenhouse gas emissions, soil erosion, water pollution, and threatened humans health. Let’s stop this from harming our environment and take action about this today. Organic farming has a smaller carbon footprint, conserves and builds soil, replenishes natural ecosystems for cleaner water and air, all with a toxic pesticide residues.
Answer:

Explanation:
Hello,
In this case, the combustion of methane is shown below:

And has a heat of combustion of −890.8 kJ/mol, for which the burnt moles are:

Whereas is consider the total released heat to the surroundings (negative as it is exiting heat) and the aforementioned heat of combustion. Then, by using the ideal gas equation, we are able to compute the volume at 25 °C (298K) and 745 torr (0.98 atm) that must be measured:

Best regards.
Answer:
light bends and makes effects in the water
Explanation:
Answer:
A gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure of 32.5 kPa.
<u>The pressure for oxygen is 3 kPa</u>
Explanation:
According to Dalton's Law of Partial Pressure total exerted by the mixture of non-reacting gases is equal to sum of the partial pressure of each gas.

So,
For , a gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure:
