The structure and history of Earth and what forces formed it. The investigation of earth in the context of the solar system and universe
Are carried on chromosomes.
Not sure about the "determined traits", but genes do determine many traits in the organism.
Answer:
BaN, Ba₃N₂
Explanation:
In order to determine the empirical formula of a compound, we have to follow a series of steps.
Step 1: Determine the percent composition
Step 2: Divide each percentage by the atomic mass of each element
Step 3: Divide all numbers by the smallest one
Step 4: If necessary, multiply by a number so the coefficients are whole
Compound 1
Step 1
Ba: 90.745%
N: 100% - 90.745% = 9.255%
Step 2
Ba: 90.745/137.33 = 0.66078
N: 9.255/14.01 = 0.6606
Step 3
Ba: 0.66078/0.6606 ≈ 1
N: 0.6606/0.6606 = 1
The empirical formula is BaN.
Compound 2
Step 1
Ba: 93.634%
N: 100% - 93.634% = 6.366%
Step 2
Ba: 93.634/137.33 = 0.68182
N: 6.366/14.01 = 0.4544
Step 3
Ba: 0.68182/0.4544 = 1.5
N: 0.4544/0.4544 = 1
Step 4
Ba: 1.5 × 2 = 3
N: 1 × 2 = 2
The empirical formula is Ba₃N₂.
