Kilauea volcano in Hawaii emits 200-300 tons of sulfur dioxide into the atmosphere each day. This is an example of
- the impact of natural processes on the earth's environment.
- air pollution from a natural source.
- the magnitude of the chemistry associated with the environment.
Kilauea volcano in Hawaii emits noxious compounds of sulfur dioxide and other harmful pollutants as a result of a reaction with atmospheric water vapors and oxygen.
This reaction results in acid rain and volcanic smog which pollutes the air.
Over the years, the volcano has become a potential threat to health as harmful oxides are accelerating respiratory problems and acid rain destroys crops, and also harms water supplies.

Answer:
9.25
Explanation:
Let first find the moles of 
and 
number of moles of = 0.40 mol/L × 200 × 10⁻³L
= 0.08 mole
number of moles of = 0.80 mol/L × 50 × 10⁻³L
= 0.04 mole
The equation for the reaction is expressed as:
The ICE Table is shown below as follows:
Initial (M) 0.08 0.04 0
Change (M) - 0.04 -0.04 + 0.04
Equilibrium (M) 0.04 0 0.04
for buffer solutions
since they are in the same solution
Newton first law of motion
Explanation:
This law by Newton states that an object will remain at rest, or a moving object will stay in motion in a straight line and with the same speed unless an external and unbalanced force acts on the object.
One application of this Newtonian law is in the launching of projectiles like ballistic missiles. A ballistic missile parabolic path is affected by its inertia and the unbalanced forces acting on the object such as air resistance/ drag and gravity.
The system is isothermal, so we use the formula:
(delta)G = (delta)H - T (delta) S
Plugging in the given values:
(delta)G = -220 kJ/ mol - (1000K) (-0.05 kJ/mol K)
(delta)G = -170 kJ/mol
If we take a basis of 1 mol, the answer is
D. -170 kJ
