How many more electrons does each oxygen atom need to be stable?

1 answer:

8 0

The answer for that question is 2 because oxygen has six valence electrons in its outer shell and there are eight electrons are needed to fill the second level to achieve stability so oxygen needs 2 more electrons to be stable your welcome :)

Determine if the phrases below are true for catabolic pathways only, anabolic pathways only,or can apply to both pathways, by so

Ivan

Answer:

Catabolic pathways;

Pathway produces more ATP than it consumes

Supplies NADH for oxidative phosphorylation

Anabolic pathways only:

Consumes more ATP than it produces

Can require reducing agent

Both pathways;

At least one enzyme is regulated

All reactions are catabolized by enzymes

One or more reactions are endergonic without ATP

Explanation:

Catabolic pathways;

Complete oxidation of glucose and then produces more ATP. Oxidative phosphorylation is an example of catabolic pathway.

From the given following conversions are considered as catabolic pathways.

Pathway produces more ATP than it consumes

Supplies NADH for oxidative phosphorylation

Anabolic pathways:

Anabolic pathways produces new molecules and it requires energy in the form of ATP for the formation of new bonds.

From the given following conversions are considered as anabolic pathways.

Consumes more ATP than it produces

Can require reducing agent.

Both pathways;

Metabolic pathways are occuring in the cell only few enzymes are regulate these pathways.

At least one enzyme is regulated

All reactions are catabolized by enzymes

One or more reactions are endergonic without ATP

What is the molality of a solution of water and kcl if the freezing point of the solution is –3mc030-1.jpgc?

Natasha_Volkova [10]

We will use the expression for freezing point depression ∆Tf
∆Tf = i Kf m
Since we know that the freezing point of water is 0 degree Celsius, temperature change ∆Tf is
∆Tf = 0C - (-3°C) = 3°C
and the van't Hoff Factor i is approximately equal to 2 since one molecule of KCl in aqueous solution will produce one K+ ion and one Cl- ion:
KCl → K+ + Cl-
Therefore, the molality m of the solution can be calculated as
3 = 2 * 1.86 * m
m = 3 / (2 * 1.86)
m = 0.80 molal

If you mixed three Dixie cups’ contents together containing 0.05L of 1.0M lemonade, 0.05L of 2.5M lemonade, and 0.05L of 0.5M le

viva [34]

Molarity of the resulting solution will be 1.33 M.

Explanation:

First we have to find the number of moles for each of the solution using the formula, moles = molarity × volume

For cup 1 = 1 M ×0.05 L = 0.05 moles

For cup 2 = 2.5 M × 0.05 L= 0.125 moles

For cup 3 = 0.5 M × 0.05 L = 0.025 moles

Total moles = 0.05 + 0.125 + 0.025 = 0.2 moles

We have to find the total volume as, 0.05 + 0.05 + 0.05 = 0.15 L

Now we have to find the molarity as, moles / volume = 0.2 moles/ 0.15 L = 1.33 M

Answer:

Both contain a hydroxyl group on the second carbon.

Neither contain a hydroxyl group on an end chain carbon.

Explanation:

2,2-butanediol Formula: C4H10O2

2,3,4-pentanetriol Formula: C5H12O3

Both contain a hydroxyl group on the second carbon.

Neither contain a hydroxyl group on an end chain carbon.
