Amino acids are the building blocks of proteins and are made from basic amino group (−NH2) and an acidic carboxyl group (−COOH) as well an organic R group (or side chain) that is unique to each amino acid. they are made from carbon, hydrogen, oxygen and nitrogen atoms
Answer:
See the steps below (8,681.25 g of will be needed0
Explanation:
From the equation, 4 moles of H2 requires 1 mole of Fe3O4.
1st step: calculate the number of mole of 300 g of H2.
mole = mass/molar mass
Mole of 300 g H2 = 300/2 = 150 mole
Hence, 150 moles of H2 will require: 150/4 = 37.5 moles of Fe3O4.
Step 2: Use the mole of Fe3O4 to calculate the mass of Fe3O4
mass = mole x molar mass
mass of 37.5 mole Fe3O4 = 37.5 x 231.5 = 8,681.25 g
Hence, 8,681.25 g of Fe3O4 will be required to completely react with 300 g H2
Answer:
Oxygen
Explanation:

Answer:
The correct answer will be option B .
Explanation:
Mitosis is a type of cell division which is divided into two phases: karyokinesis and cytokinesis. The karyokinetic phase is categorized into four stages: prophase, metaphase, anaphase and telophase.
Interphase is the metabolic phase of the cell division in which the chromosomes appears in the form of a loose structure called chromatin in the nucleus. The chromatin is present in the same nuclear territory as their homologs present in the same nucleus.
Thus, option B is the correct answer.
