Cost of production reports can also be used to compare the materials output quantity to the a.administrative staff input quantit
valentinak56 [21]

Answer:

b.materials input quantity

Explanation:

A cost of production report shows the following:

  • total and unit costs transferred from preceding department
  • materials, labor , factory Overhead added by the department
  • unit costs added by the department
  • total and unit costs accumulated to the end of operations
  • the cost of beginning and ending work in process inventories
  • the cost transferred to the next department

A cost of production report determines periodic total and unit costs.

Either in the cost of production report or in the supporting schedule each item of material used is listed, every labor operation is shown separately,factory overhead components are noted individually, and a unit cost is derived for each item.

A Quantity Schedule Of Cost of Production report  shows the following

  • units started in process
  • units transferred to next department
  • units still in process
  • units lost in process

Glycolysis is the process by which energy is harvested from glucose by living things. Several of the reactions of glycolysis are
nika2105 [10]

Answer: Reaction A: pi + glucose ⇒ glucose-6-phosphate + H2O ΔG = 13.8 kJ/mol

Reaction B: pi + frutose-6-phosphate ⇒fructose-1,6-biphosphate + H2O ΔG = 16.3kJ/mol

Explanation: ΔG is the representation of the change in Gibbs Free Energy and relates enthalpy and entropy in a single value, which is:

ΔG = ΔH - TΔS

where:

ΔH is enthalpy

T is temperature

ΔS is entropy (measure of the )

It can also predict the direction of the reaction with the conditions of temperature and pressure being constant.

When the change is positive, the reaction is non-spontaneous, which means the reaction needs external energy to occur. If the change is negative, it is spontaneous, i.e., happens without external help.

Analyzing the reaction, we see that reaction A and B have a positive ΔG, while reaction C is negative, so the reaction that are unfavorable or nonspontaneous are <u>reactions A and B</u>.
