Answer:
35 mL
Explanation:
Let the amount of 75% mixture needed be A.
The amount of each solution with their respective concentration to be added together can be expressed as:
0.75A + 0.3(280)...............eqn 1
The addition of the two solution must merge with the expected concentration and this can be expressed as:
0.35(A + 280).............eqn 2
Eqn 1 must be equal to eqn 2, hence:
0.75A + 0.3(280) = 0.35(A + 280)
Solve for A.
0.75A + 84 = 0.35A + 98
0.40A = 14
A = 35
Hence, 35 mL of the 75% mixture will be needed.
The main difference between the 3 isotopes of hydrogen are the number of neutrons in the nucleus. Hydrogen has no neutrons, Deuterium has one neutron, and tritium has two neutrons. All three have one proton and one electron.
As we know that <span>Boron has 6 valence electrons
So it does not have to fill a complete octet. it just need two electrons
Thus B(CH3)3 will have only 3 electron domains, and it will constitute</span> a trigonal structure.

Answer:
I don't remember how to label it, but it is 20.
Explanation:
The answer is 20 because once you dat the rock in the water, that is how much it changed.
Answer: 1. h oxidized, 2. g reduced, 3. e glucose, 4. c pyruvate, 5. b NAD+, 6. a NADH.
Explanation:
Glycolysis is also known as Embden-Meyerhof pathway, and in this process one mole of glucose is oxidised into two moles of pyruvate in a series of enzyme-catalyzed reaction and do not involve molecular oxygen i.e. oxygen indepenedent process. This process is studied in two phases preparatory (energy-investment) and pay-off phase(energy generation).
Net reaction: Glucose + 2NAD+ HPO4-2 = 2 Pyruvate + 2NADH + 2ATP + 2H2O.
