based on distance to the nearest water well, which drilling site would pose the least risk of methane contamination?

1 answer:

7 0

Based on distance to the nearest water well, the drilling site that would pose the least risk of methane contamination would be the one farthest away from the water well.

Methane is a gas that is known to escape from the ground and rise up into the atmosphere. If the drilling site is too close to the water well, there is a greater risk that the methane could contaminate the water.

The atmosphere is the air that surrounds us. It is a mixture of gases, including nitrogen, oxygen, and carbon dioxide. The atmosphere protects us from the Sun's ultraviolet radiation and from the cold of space. It also contains the Earth's weather, which is caused by the Sun's energy.

Given the reaction that occurs in an electrochemical cell:

KatRina [158]

Answer:

c) +2 to 0

Explanation:

SO4 has a charge of -2, so the Cu attached to that has to be a +2 since the polyatomic molecule has no overall charge

Cu(s) is a solid metal and they have no charge, therefore it is zero

Copper undergoes Oxidation (gain of electrons)

What is the mass in grams of 85.32 mL of blood plasma with a density of 1.03 g/mL

sveticcg [70]

Well if you're looking for grams, all you need to do is cancel out units. (ml)(g/ml)=g because the ml cancels out. Thus, multiply: (85.32ml)(1.03g/ml)=...I'll let you solve this. :) Good luck! Hope that helped. When in doubt, look at the units.

What is the percent composition of hydrogen if a sample is found to contain 7 grams of hydrogen, 32 grams of nitrogen, and 7 gra

nata0808 [166]

Answer: The percent composition of hydrogen in the sample is 15.22 %

Explanation:

We are given:

Mass of hydrogen = 7 grams

Mass of nitrogen = 32 grams

Mass of carbon = 7 grams

Total mass of the sample = 7 + 32 + 7 = 46 grams

To calculate the percentage composition of hydrogen in sample, we use the equation:

$\%\text{ composition of hydrogen}=\frac{\text{Mass of hydrogen}}{\text{Mass of sample}}\times 100$

Mass of sample = 46 g

Mass of hydrogen = 7 g

Putting values in above equation, we get:

$\%\text{ composition of hydrogen}=\frac{7g}{46g}\times 100=15.22\%$

Hence, the percent composition of hydrogen in the sample is 15.22 %
