Answer:
Explanation:
6.90 mol x grams
2As + 6NaOH = 2Na3AsO3 + 3H2
6 mol 2 mol
192 g/mol
6.90 mol NaOH x 2 mol Na3AsO3/6 mol NaOH== 2.3 mol Na3AsO3
2.3 mol Na3AsO3 x 192 g/mol = 442 g Na3AsO3
The units for measuring ions, molecules or atoms are called moles. Water decomposes to form hydrogen and oxygen as follows:
Moles of hydrogen produced will be:
Option C. 12.6 mol
The moles can be estimated as:
- The molar ratios can be written as:
2 mol : 2 mol : 1 mol
- The proportions and theoretical values are written as:
Let the moles of = X
Then,
From this it can be depicted that hydrogen produced is double compared to oxygen produced.
Solving further for X:
Therefore, 12.56 moles are produced of hydrogen.

Explanation:
I dont know that's all you need
Answer:
1.) The total possible combination of alleles for those genes in humans is approximately 70,368,744,177,664. This is trillions of times more combinations than the number of people who have ever lived. This accounts for the fact that nearly everyone, except m0n0zyg0tic twins, is genetically unique.
2.) A hom0zyg0us recessive allele c0mbination contains two recessive alleles and expresses the recessive phen0type. For example, the gene for seed shape in pea plants exists in two forms, one form (or allele) for round seed shape (R) and the other for wrinkled seed shape (r).
4.) If the alleles are heteryg0us recessive, the faulty allele would be recessive and not express itself. Instead, the person would be a carrier. If the alleles are heterozyg0us dominant, the faulty allele would be dominant.
