Schach [20]

Answer:

The options are

a. occur inside organelles. b. start over continually. c. are part of the carbon cycle. d. allow energy to flow in ecosystems.

The answer is b. Start over continually

Explanation:

The two cycles involves a continuous process as long as the reactants are present under suitable conditions. The cycle happens all the time due to it being necessary to produce important products all the time for the body system.

A good example involves the existing Carbon dioxide and water reacting together to get converted into substance that could provide energy (ATP and NADH) such as Glucose.

aleksley [76]

Answer:

b. AZ BX

Explanation:

A⁺, B⁺, X⁻, Y⁻ and Z⁻

AX(aq)+BY(aq)→no precipitate

AX(aq)+BZ(aq)→precipitate.

AX(aq)+BY(aq)→no precipitate:

A⁺ (aq) + X⁻ (aq) + B⁺ (aq) + Y⁻ (aq) → AY (aq) + BX (aq)

AX(aq)+BZ(aq)→precipitate:

A⁺ (aq) + X⁻ (aq) + B⁺ (aq) + Z⁻ (aq) → AZ (s) + BX (aq)

Considering the reactions above, the insoluble specie is AZ.

Place these hydrocarbons in order of decreasing boiling point:
Delvig [45]

The given compounds are alkanes. This means that the formula is C_nH_2n+2

The general trend for boiling point in alkanes is that the greater number of carbon atoms, the higher the boiling point. If the alkane is branched, the branched alkane will have a higher boiling point than the straight chain.

Taking these into account: propane < heptane < triptane < hexadecane < paraffin
