Answer:
B
Explanation:
A chemical reaction equation is balanced if the number of atoms of each element on the right hand side of the reaction equation is the same as the number of atoms of the same element on the left hand side of the reaction equation.
By inspection, the chemical reaction written in the question is a balanced chemical reaction equation.
However, the statement in option B that more molecules of N2 are needed to produce NH3 than molecules of H2 is a false statement since only one mole of N2 and three moles of H2 are required to produce NH3 according to the reaction equation as written in the question.
Deposits
Explanation:
Glaciers also deposits materials in new places when they melt.
- Glaciers are made up of snow flakes that has compressed through time.
- In temperate and polar regions where they are prevalent, they are powerful agents of denudation.
- They can erode, transport and deposit earth materials in places.
- When a glacier retreats by melting, it deposit some of its materials in new places.
- Most of this sediment are called tillites.
- They are made up of unsorted materials of different size grains.

Answer:
53.87g
Explanation:
Given parameters:
Percentage by mass of Nitrogen in fertilizer = 19%
Mass of fertilizer = 10.0oz
Unkown:
Mass in grams of Nitrogen in the container = ?
Solution
To solve this problem, we first find the percentage of mass of nitrogen in the fertilizer by a taking a percentage of the given mass of the fertlilizer:
Mass of Nitrogen in ounces of the fertilizer =
x 10 = 1.9oz
Since we are expected to express this in grams:
1oz = 28.35g
1.9oz = 1.9 x 28.35, 53.87g
Explanation:
Atomic radius decreases from left to right in a period.
Therefore Calcium would have a smaller atomic size.
