Information related to a titration experiment is given in the balanced equation and table below.
Scorpion4ik [409]

Answer:

0.24M

Explanation:

The equation for the reaction is given below:

H2SO4 + 2KOH → K2SO4 + 2H2O

From the equation above, we obtained the following information:

nA (mole of acid) = 1

nB (mole of base) = 2

Data obtained from the question include:

Va (volume of the acid) = 12mL

Ca (concentration of the acid) =?

Vb (volume of the base) = 36mL

Cb (concentration of the base) = 0.16 M

The Ca (concentration of the acid) can be obtained as follow:

CaVa/CbVb = nA/nB

Ca x 12 / 0.16 x 36 = 1 /2

Cross multiply to express in linear form as shown below:

Ca x 12 x 2 = 0.16 x 36

Divide both side by 12 x 2

Ca = 0.16 x 36/ 12 x 2

Ca = 0.24M

Therefore, the concentration of the acid is 0.24M

Weathered debris is a result of
tresset_1 [31]
Weathered debris is a result of FROST WEDGING.
Frost wedging refers to the process by which water freeze and thaw continuously over a period of time. Rocks usually contain crevices which are filled with water. Due to the extreme temperature changes during the night and day and during the course of season changes, the water in the crevices freeze and thaw continuously leading to the cracking of the rocks as a result of the expansion and contraction of the rocks.<span />

g Lactate dehydrogenase is a tetrameric enzyme (144kDa) that catalyzes conversion of pyruvate into lactate to regenerate NAD in
kotegsom [21]

Answer:

Kindly check the explanation.

Explanation:

NADH is oxidized anaerobic conditions by lactate dehydrogenase because in order to transform or change Pyruvate into Lactate it has to happen in an anaerobic condition that is where we hardly find oxygen(in the presence of no oxygen).

The chemical compound or say the enzyme known as lactate dehydrogenase gets its proton from NADH( in a REDOX type reaction). After getting the proton from NADH, it uses that to convert Pyruvate into Lactate.

NB: the conversion can also be done in aerobic condition but more ATP will be produced. With anaerobic condition, less ATO is produced and there is re-oxidation.
