Answer:

No because the statue is discolored from weathering.

Explanation:

Since the statue was already discolored, that means the substance has been acted upon by a process known as weathering .

Weathering is the breaking down of rocks or dissolving of rocks by the action of rain water, biological activities and temperatures changes. Weathering may be mechanical or chemical . Mechanical weathering live no changes in the overall chemical change of the weathered rock.

Chemical weathering usually occurs when rain water reacts with mineral constituent of rock to form a new minerals like clay and soluble salt. The Chemical changes can be more rapid if the rain water is slightly acidic. The rainwater in the presence of oxygen(oxidation),  because of it acidity may have caused the discoloration of the granite rock. Rain water will likely promotes weathering not the other way round

According to Newton's third law, forces come in pairs. There is_____and an equal and opposite_____.
hichkok12 [17]

According to Newton's third law, forces come in pairs. There is action-reaction force and an equal (in size - action force) and opposite in direction (reaction force).

<u>Explanation:</u>

On the off chance, when item A applies a force on item B, at that point item B must apply a force of equivalent size and inverse bearing back on object A. This Newton's third law speaks to a specific balance in nature: forces consistently happen two by two.

And, one body can't apply a force on another without encountering a force itself. Now and again, allude to this law freely as activity response, where the force applied is the activity and the force experienced as a result is the response.

How are stars and comets different?
ehidna [41]
The answer is letter C.

Because we classify something as a star when it is: a large ball of gas that undergoes nuclear fusion. Given this definition, a comet is not a star. A comet is a ball of ice and dirt hurtling through space, it shines only because it reflects ligh

Answer:

0.07172 L = 7.172 mL.

Explanation:

  • We can use the general law of ideal gas: <em>PV = nRT. </em>

where, P is the pressure of the gas in atm (P = 1.0 atm, Standard P).

V is the volume of the gas in L (V = ??? L).

n is the no. of moles of the gas in mol (n = 3.2 x 10⁻³ mol).

R is the general gas constant (R = 0.0821 L.atm/mol.K),

T is the temperature of the gas in K (T = 273 K, Standard T).

<em>∴ V = nRT/P =</em> (3.2 x 10⁻³ mol)(0.0821 L.atm/mol.K)(273 K)/(1.0 atm) = <em>0.07172 L = 7.172 mL.</em>
