Answer:
M = 35 g/mol
Explanation:
Given data:
Density = 2.5 g/L
Pressure = 1.8 atm
Temperature = 30°C (273.15 +30 = 303.15 K)
Molar mass = ?
Solution:
d = PM/RT
M = dRT/P
M = 2.5 g/L × 0.0821 atm.L/mol.K × 303.15 K / 1.8 atm
M = 62.22 atm. g/mol/ 1.8 atm
M = 35 g/mol
Answer:
The phosphorylation of glucose to glucose-6-phosphate is endergonic reaction that is coupled to the exergonic hydrolysis of ATP.
Explanation:
In glycosis, the first reaction that takes place is the phosphorylation of glucose to glucose-6-phosphate by the enzyme hexokinase. This is an exergenic reaction. This is a coupled reaction in which phosphorylation of glucose is coupled to ATP hydrolysis. The free energy of ATP hydrolysis fuels glucose phosphorylation.
The term monomer refers to a unit made up of several atoms.This will make the correct answer B.
Explanation:
An elimination reaction is a type of organic reaction in which two substituents are removed from a molecule in either a one or two-step mechanism. The one-step mechanism is known as the E2 reaction, and the two-step mechanism is known as the E1 reaction.
Another definiton is;
Elimination reaction, any of a class of organic chemical reactions in which a pair of atoms or groups of atoms are removed from a molecule, usually through the action of acids, bases, or metals and, in some cases, by heating to a high temperature. It is the principal process by which organic compounds containing only single carbon-carbon bonds (saturated compounds) are transformed to compounds containing double or triple carbon-carbon bonds (unsaturated compounds).
Strong Acids play two key roles in elimination reactions:
1. Without the acid catalyst, the reaction is painfully slow.
2. Acid greatly facilitates elimination of the leaving group.
