Answer:
chemical
Explanation:
Chemical weathering, which is the decomposition of a rock by the alteration of its chemical composition.
Explanation:
We know that,
1 mile = 1609.34 m
We need to find how many meters are present in the 12.45 miles. To find it use unitary method as follows :
12.45 mile = 1609.34 × 12.45
12.45 mile=20036.283 meters
or

Hence, this is the required solution.
The number of neon moles that occupy a volume of 14.3 l at STP is calculated as follows
At STP 1 mole = 22.4 liters
what about 14.3 liters
by cross multiplication
= (1 mole x 14.3 l)/22.4 l =0.638 moles of neon
Total number of atoms = 7
Total number of H atom = 5
% of H in ammonium hydroxide = 5/7 ×100 = 71.4 %
NO3- will affect the pH of a solution. The ion will decrease the pH of a neutral solution. No3- ion is a conjugate base of a strong acid, therefore, if it added to a neutral solution of pH 7, it will change the pH of the solution by decreasing the pH, that is, the solution will become acidic in nature.
