Natural gas or methane is a fossil fuel. In a plentiful supply of air, it burns to give carbon dioxide and water. Write a balanc
Alex17521 [72]

Answer:

CH_4 + 2O_2 --> CO_2 + 2H_2O

Explanation:

The chemical formula for methane is CH_4

The chemical formula for oxygen is O_2

The chemical formula for carbon dioxide is CO_2

The chemical formula for water is H_2O

Methane burns in oxygen to give carbon dioxide and water:

CH_4 + O_2 --> CO_2 + H_2O

The balanced equation that will ensure an equal number of each atom on the left and right-hand sides of the equation would be:

CH_4 + 2O_2 --> CO_2 + 2H_2O

The exponents in the rate law of an elementary step are always equal to the coefficients of each species in the balanced reactio
Naya [18.7K]

Answer:

True

Explanation:

True. Since in an elementary step , the reaction procedes by collision of the atoms of reactants involved and since the rate of collision is proportional to the concentration of each atom that participates in the elementary step , the exponents in the rate law of the elementary step always coincides with the coefficients that correspond to that reaction ( regardless if is unimolecular, bimolecular or trimolecular).

hich of the followings decrease the affinity of adult Hb with O2? A. 2,3 BPG B. hydrogen ion C. CO2 D. Ferrous ion
Ivahew [28]

Answer:

A. 2,3 BPG

Explanation:

2,3-bisphosphoglycerate (BPG), otherwise known as 2,3-DPG, enables the transition of hemoglobin from a very high-oxygen-affinity state to a reduced-oxygen-affinity state.

Tissues hemoglobin oxygen affinity is reduced by numerous physiological factors including.

1. Temperature Increased,

2. Carbon dioxide,

3. Acid and

4. 2,3-Bisphosphoglycerate (2,3-BPG)

all of which can contribute to decrease the oxygen affinity of hemoglobin which favours unloading and increased oxygen availability to our body cells.
