Answer:

Law of Conservation of Mass

Explanation:

Balancing chemical equation means that the amount of moles of one atom on side must match the other, which makes sure that no atoms are created nor destroyed in the reaction process.

the deltag value for the acontinase reaction is 5.8 kj/mol. what is the ratio of isocitrate/citrate understandard conditions?

soldi70 [24.7K]

The ratio of isocitrate/citrate under standard conditions is 0.096 when the value of ΔG° is given by 5.8kj/mol.

We know that isocitrate and citrate are convertible. It is given that the ΔG° is given by 5.8kj/mol. Then we know that,

ΔG° = -RTlnK

lnK = -RT/ΔG°

On substituting the values, we get

lnK = -5.6x10³/(6.314x296)

lnK = -2.34

K = 0.09623

The value of k is 0.09623.

Therefore, the ratio of Isocitrate to citrate is given by,

[Isocitrate]/[Citrate] = 0.09623

The ratio could be however rounded off to 0.096.

Therefore, the ratio is given by 0.096 for the isocitrate/citrate under standard conditions. In this way, the ratio could be computed very easily.

the atomic mass of chlorine is 35.45 u. is it possible for any single atom of chlorine to have a mass number of exactly 35.45? e

Allushta [10]

The mass of Cl on the periodic table is 35.45 atomic mass units. This is an average mass of the isotopes of chlorine. Most Cl atoms in nature have a relative mass of about 35 atomic mass units. Most of the remaining Cl isotopes have a relative mass of 37 atomic mass units.

The number 35.45u is the result of the natural mixture of Cl-35 and Cl-37, which produces the observed value.

Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as a primary standard. It has the unw

Sauron [17]

Answer:

0.1472 mol/L is the concentration of the barium hydroxide solution.

Explanation:

$2KHC_8H_4O_4+Ba(OH)_2\rightarrow Ba(KC_8H_4O_4)_2+2H_2O$

Mass of potassium hydrogen phthalate = 2.050 g

Molar mass of potassium hydrogen phthalate = $\frac{2.050 g}{204.2 g/mol}=0.01004 mol$

According to reaction , 2 moles of potassium hydrogen phthalate reacts with 1 mole of barium hydroxide, then 0.01004 moles of potassium hydrogen phthalate will :

$\frac{1}{2}\times 0.01004 mol=0.005020 mol$ of barium hydroxide

Moles of barium hydroxide = 0.005020 mol

Volume of the barium hydroxide solution = 34.10 mL = 0.03410 L

1 mL = 0.001 L

$Molarity=\frac{Moles}{Volume(L)}$

Molarity of the barium hydroxiude silution :

$=\frac{0.005020 mol}{0.03410 L}=0.1472 mol/L$

0.1472 mol/L is the concentration of the barium hydroxide solution.
