Answer:
Reaction Quotient, Kq = {[a-ketoglutarate]x[L-alanine]}/{[L-glutamate]x[pyruvate]}
or, Kq = {(1.6x10-2)x(6.25x10∧-3)}/{(3x10∧-5)x(3.3x10-4)} = 1.01 x 10∧4
Since Kq > Keqb ; therefore the reaction will proceed in the backward direction, in order words the reaction will not occur in forward direction. i.e formation of reactants will be favored.
Explanation:
Given-
Hydrogen ion concentration pH = 0.008
Now,
we know that pH + pOH = 14
pOH = 14-0.008
pOH = 13.992
Answer
The molarity (M) of the H3PO4 solution = 1.0 M
Explanation
Given:
Mass of H3PO4 = 49.0 grams
Volume of the solution = 500 mL = 500/1000 = 0.5 L
What to find:
The molarity (M) of the H3PO4 solution.
Step-by-step solution:
Step 1: Convert 49.0 grams H3PO4 to moles using the mole formula.
The molar mass of H3PO4 = 97.994 g/mol
So,
Step 2: Calculate the molarity of the solution using the molarity formula.
Putting mole = 0.50 mol and volume = 0.50L into the formula, we have;
The molarity (M) of the H3PO4 solution = 1.0 M
Answer:
To allow all the elements or compounds to separate complete.
Explanation:
In chromatography, the compounds need some space and time to separate, one from each other, if you just use the half of the paper strip maybe you will not notice the different spots of compounds. Remember all the substances have different affinity for the solvents, that means, some react very quickly but others need more time as the colors that conform the black color in an ink.
With a physical change you can actually see it change like ice turning into water, then with a chemical change you can't see it change, although within the molecules themselves they change which makes that possible.
Hope this helps!
