B. 1, 2, 1, 2. You balance the equation by making sure there are equal elements on both sides.
Both elements and compounds are pure substances. While elements are not made of simpler substances, compounds are made up of two or more chemical elements that are chemically combined.
The answer is G. choices b and c only
Answer:
Explanation:
The unbalanced nuclear equation is
Let's write the question mark as a nuclear symbol.
The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.
Then
15 = 0 + A, so A = 15 - 0 = 15, and
6 = -1 + Z, so Z = 6 + 1 = 7
Then, your nuclear equation becomes
Element 7 is nitrogen, so the balanced nuclear equation is
Answer:
Most of free energy available from oxidation of the glucose remains in pyruvate.
Explanation:
The overall reaction of the process glycolysis is:
Glucose + 2 NAD⁺ + 2 ADP + 2 Pi ⇒ 2 Pyruvate + 2 NADH + 2 H⁺ + 2ATP
Glucose is oxidized to give 2 molecules of pyruvate and 2 molecules of NADH and ATP (Energy currency).
<u>Though the free energy of oxidation of glucose is high but only 2 NADH is formed because the most of the free energy that is being released from the oxidation of glucose remains in the pyruvate which is produced in the reaction and thus only 2 molecules are formed.</u>
