Answer: 4Fe+3O_2\rightarrow 2Fe_2O_3

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.

The chemical equation for synthesis of Fe_2O_3 from Fe and O_2 is:

4Fe+3O_2\rightarrow 2Fe_2O_3

lara [203]

Answer:

bonding molecular orbital is lower in energy

antibonding molecular orbital is higher in energy

Explanation:

Electrons in bonding molecular orbitals help to hold the positively charged nuclei together, and they are always lower in energy than the original atomic orbitals.

Electrons in antibonding molecular orbitals are primarily located outside the internuclear region, leading to increased repulsions between the positively charged nuclei. They are always higher in energy than the parent atomic orbitals.

Marat540 [252]

Answer:

Option C.

The Bohr effect describes the effect of pH on the affinity of hemoglobin for oxygen.

Explanation:

The hemoglobin is the oxygen carrying part of the blood. However, According to Christian Bohr, the binding affinity for oxygen by the hemoglobin in the blood is greatly affected by the acidity and content of carbon dioxide in the blood. As a matter of fact, they are inversely related. The more acidic the blood is, or the lower the pH of the blood, the lower the amount of oxygen that can become bonded with the hemoglobin in the blood.
