Chemistry
1 answer:
Vlada [557]3 years ago
6 0

Answer:

This question is incomplete and it lacks options. The complete question is as follows;

In condensation reactions, the atoms that make up a water molecule are from what?

a. oxygen

b. only one of the reactants

c. both of the reactants

d. carbohydrates

e. enzymes

The answer is C. Both of the reactant

Explanation:

In a chemical reaction, two small molecules called monomers combine to form a much larger molecule called polymer in a process called CONDENSATION REACTION. Some condensation reactions is characterized by the release of a water molecule (dehydration).

This water molecule is formed as a result of the active participation of both reactants. During the reaction, hydroxyll group (-OH) from one of the reactants breaks off and combines with hydrogen ion (H+) from the other reactant to form water molecule (H2O).

Hence, the atoms that make up the water molecule come from both of the reactants participating in the condensation reaction.

HELP!!!!!
faltersainse [42]

Answer:

5.17.

Explanation:

<em>∵ [H₃O⁺][OH⁻] = 10⁻¹⁴. </em>

[OH⁻] = 1.5  x 10⁻⁹ M.

∴ [H₃O⁺] = 10⁻¹⁴/[OH⁻] = 10⁻¹⁴/(1.5  x 10⁻⁹ M) = 6.66 × 10⁻⁶ M.

∵ pH = - log[H₃O⁺]

<em>∴ pH = - log(6.66 × 10⁻⁶ M) = 5.17. </em>

Are the following statements true or false? (a) Formal charges represent an actual separation of charges. true false (b) ΔH o rx
katrin [286]

Answer:

Explanation:

A) Formal charges represent an actual separation of charges.(FALSE)

(B) ΔHo rxn can be estimated from the bond enthalpies of reactants and products.(TRUE)

C)All second-period elements obey the octet rule in their compounds(FALSE).

(D)The resonance structures of a molecule can be separated from one another in the laboratory.(FALSE)

Bond enthalpy which is also reffered to as bond energy is the amount of energy that is required to break one mole of a bond.

taking the single bond between Oxygen and Hydrogen into considerationthe bond energy between their single bond is 463 kJ/mol.

formal charge is used for the comparison of the number of electrons present around an atom in a particular molecule with the number of electrons present around a neutral

7. Suppose each of these isotopes emits a beta particle. Give the iso-
Volgvan

In a beta emission, the mass number of the daughter nucleus remains unchanged while the atomic number of the daughter nucleus increases by one unit. The following are isotopes produced when the following undergo beta emission;

1) potassium-42  ------> Ca - 42

2) iodine-131 ------------> Xe - 131

3)  iron-52 ---------------> Co - 52

4)  sodium-24 -----------> Mg -24

The daughter nucleus formed after beta emission is found one place after its parent in the periodic table.

Regarding the stability of the daughter nuclei, a nucleus is unstable if the neutron-proton ratio is less than 1 or greater than 1.5.

Hence, the following daughter nuclei are stable; Ca - 42, Xe - 131, Mg -24.
