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
It is given that the charge on potassium is +1 i.e. Potassium is a cation, K⁺
The charge on selenium is given as -2, i.e. selenium is an anion, Se²⁻
The two ions are shown to combine to form a molecule: KXSeY where X and Y correspond to the proportions in which the two atoms combine.
Since the molecule is neutral, the positive and negative charges need to be balanced. This is possible only if 2 units of K⁺ combines with 1 unit of Se²⁻.
Therefore, the formula would be K₂Se
X = 2 and Y = 1
Answer:
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products.
Explanation:
If it’s multiple answers then it’s A,C,D. If it’s only one answer then your best answer is A. Because you always report accidents to an authority so that they can figure out how to solve the problem.
