based on distance to the nearest water well, which drilling site would pose the least risk of methane contamination?
Marysya12 [62]

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.

For the product of the reaction below, which proton is removed irreversibly by NaNH2 base, thus preventing any isomerization of
Serggg [28]

Answer:

The Highly acidic proton joined to one of the carbon in the ALKYNE bond.

(Kindly Check the attachment for the drawing because the solution will need us to draw).

Explanation:

So, let us start by defining some major key terms in this particular Question given above;

(1). ISOMERIZATION: isomerization can simply be defined as the kind is of chemical rearrangement whichay lead to the breaking and the formation of new bonds.

(2). NaNH2 BASE: Sodium amide is a Chemical compound which has a Molar mass of 39.01 g/mol and Heat capacity (C) of 66.15 J/mol K. It is also known as sodamide. It is a good nucleophile.

(3). ALKYNE BOND: it is a C-C joined together by three bonds.

The chemical reaction given in the Question is given in the attachment too.

Therefore, The Highly acidic proton joined to one of the carbon in the ALKYNE bond  is removed irreversibly by NaNH2 base.

A gas is contained in a thick-walled balloon. When the pressure change from 100 kPa to 90.0 kPa, the volume changes from 2.50 L
Orlov [11]
The  temperature  change is   calculated using the  combined  gas law
that  is P1V1/T1  =P2V2/T2
P1=  100KPa
P2=90kpa
v1= 2.50 L
v2= 3.75 L
T1= 303 K
T2=?

T2  is  therefore  =  P2V2T1/P1V1
=( 90  x 3.75  x303)/  (100  x2.50) =  409.05  K

daser333 [38]

Answer:

Colorado river

Explanation:

The Grand Canyon is usually referred to as the large and beautiful geological landform that is formed by the continuous carving of the rocks due to the flow of the Colorado River through the canyon. It is near about 450 kilometers long and has a width of about 6.5 to 30 kilometers. This canyon covers a large area in the north-western part of Arizona in the United States.

The main agent for the cutting down of rocks here is the water. According to the research, this canyon is about 70 million years old, and the river Colorado has been flowing through this canyon from about 5-6 million years back.
