Julli [10]

When energy depleted elements associated with a proton are accepted by an organic molecule the process is called Fermentation.

Fermentation is a metabolic process that causes a chemical change inside body by the actions of enzymes.

The main purpose of fermentation is to generate NAD+ and 32 ATP in the presence of oxygen.

Fermentation allows cells to survive without using ATP.

How many mole of calcium (Ca) are in 9.00 x 1016 atoms of Ca?

d1i1m1o1n [39]

Answer:

Number mole of calcium (Ca) = 1.4942 x 10⁻⁷ (Approx.)

Explanation:

Given:

Number of atom in (Ca) = 9 x 10¹⁶

Find:

Number mole of calcium (Ca)

Computation:

Number mole of calcium (Ca) = Number of atom in (Ca) / Avogadro's number

Number mole of calcium (Ca) = (9 x 10¹⁶) / (6.023 x 10²³)

Number mole of calcium (Ca) = 1.4942 x 10⁻⁷ (Approx.)

A flask contains 5.0g of neon gas at a temperature of 35°C. The pressure gauge indicates 0.37atm inside the flask. What is the v

DaniilM [7]

Answer:

The volume of the neon gas is 17.07 L.

Explanation:

The ideal gas equation describes the relationship among the four variables P, V, T, and n. An ideal gas is a hypothetical gas whose pressure-volume-temperature behavior can be completely accounted for by the ideal gas equation.

In order to calculate the volume, first we need to convert the grams of neon to moles:

28.18 g Ne ------ 1 mol Ne

5.0 g Ne---------- x= 0.25 mol Ne

Now, using the ideal gas equation we calculate the volume:

$pV= nRT$

$V= nRT ÷ p$

$V= (0.25 mol × 0.082 L.atm/mol.K × 308.15 K ÷ 0.37 atm$

V= 17.07 L

iVinArrow [24]

Answer:

Explanation:

The alkene reactions in general are addition or oxidation reactions. For the addition reaction, we have to take into account that some of them are marknonikov and other anti-markovnikov. Also for the addition reaction, we will have to take into account if we will have anti or syn products. In the oxidation reaction, we have to know the specifics for each reaction. If the reaction can go to the highest oxidation level, is the double bond is broken, etc.

Each reaction has its specific characteristics (see figures 1 and 2).
