FALSE!  Lower pH values coordinate to MORE acidic solution.  A pH of 7 is neutral, so a pH of 8 is actually a basic solution.

What happens to the glucose molecule during the process of cellular respiration? (5 points)
Dmitry [639]

The correct answer is option a, that is, it gets broken down.  

A set of metabolic reactions and procedures, which occurs in the cells of organisms to transform biochemical energy from nutrients into ATP, and then discharge waste components is known as cellular respiration. At the time of cellular respiration, a molecule of glucose gets dissociated slowly into water and carbon dioxide. With it, some of the ATP is generated directly in the reactions, which transform glucose.

Given the reaction below, how will the concentration of D change if the concentration of B decreases by 0.045 M? 3A(g)+2B(g)⇋2C(
abruzzese [7]

Answer:

0.113 M

Explanation:

Since B and D are on opposite sides of the reaction, the concentration of D increases when the concentration of B decreases. The amount by which D increases is determined by the coefficients of B and D in the balanced chemical equation:

[D]=\frac{5}{2}(0.045 M)=0.113 M.

Hemoglobin, an iron-containing oxygen-transport protein, is 0.349% Fe by mass.
nirvana33 [79]

Answer : The molar mass of hemoglobin is, 6.40\times 10^4g/mol

Explanation : Given,

Molar mass of iron = 55.85 g/mol

0.349 % Fe by mass that means 0.349 grams of Fe present in 100 grams of hemoglobin.

or,

\text{Percent of Fe}=\frac{4\times \text{Molar mass of Fe}}{\text{molar mass of hemoglobin}}\times 100

Now put all the given values in this formula, we get:

0.349=\frac{4\times 55.85g/mol}{\text{molar mass of hemoglobin}}\times 100

\text{molar mass of hemoglobin}=64011.46g/mol=6.40\times 10^4g/mol

Thus, the molar mass of hemoglobin is, 6.40\times 10^4g/mol
