Answer:

These are all in order....

Explanation:

- closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system

- a solute is a substance dissolved in another substance, known as a solvent

- A solvent is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid

- a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent)

- a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy

- a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy.

- Half-life is the time required for a quantity to reduce to half of its initial value

- the determination of the age or date of organic matter from the relative proportions of the carbon isotopes carbon-12 and carbon-14 that it contains. The ratio between them changes as radioactive carbon-14 decays and is not replaced by exchange with the atmosphere.

- any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed

Which contains more hydrogen atoms? a five-carbon saturated hydrocarbon molecule or a five-carbon unsaturated hydrocarbon molecu
Studentka2010 [4]

The organic compound which contains more hydrogen atoms is a five-carbon saturated hydrocarbon molecule

<h3>What are organic compounds?</h3>

Organic compounds are compounds are those compounds containing carbon and hydrogen only.

Some classes of organic compounds are:

  • Alkanes
  • Alkenes
  • Alkynes

So therefore, the organic compound which contains more hydrogen atoms is a five-carbon saturated hydrocarbon molecule

katovenus [111]

Answer:

Ether

SN1 mechanism

Explanation:

The nucleophile in this reaction is CH3OH. It is a poor nucleopile. We already know that a poor nucleophile reacting with a tertiary alkyl halide often leads to the substitution product as the major product.

Also, the iodide ion is a good leaving group. This makes the SN1 substitution more likely yielding the ether as the major product as shown in the image attached.
