Answer:

a structural formula

Explanation:

A structural formula simply shows the arrangement of atoms on a compound or molecule.

They are mostly used in representing hydrocarbons.

Through a structural formula we can give name to a compound.

For example, the compound given is called Propane, an aliphatic hydrocarbon with 3-carbon atoms.

The bond relationship connecting the species are also shown in this designation.

Salt is the product formed by a reaction in which _______ atoms of an acid are replaced by the atoms of a metal.
UkoKoshka [18]
<span>Salt is the product formed by a reaction in which the hydrogen atoms of an acid are replaced by the atoms of a metal. The salt is formed as a result of the neutralization of the acid by base, that is the metal or positive ion replace the hydrogen ion in the acid. For instance: NaO + H2SO4 = NaSO4 + H2O. In this example, Na [sodium] has replaced the hydrogen in H2SO4, thereby forming the salt NaSO4.</span>

Ilia_Sergeevich [38]

Answer:

HOPE IT HELPS...

Explanation:

When added to ice, salt first dissolves in the film of liquid water that is always present on the surface, thereby lowering its freezing point below the ices temperature. Ice in contact with salty water therefore melts, creating more liquid water, which dissolves more salt, thereby causing more ice to melt, and so on

10095 m/sec to mile/ sec. 1 km = 0.6214 mile
Anarel [89]

Answer:

Explanation:

to convert any value in miles per second to meters per second, just multiply the value in miles per second by the conversion factor 1609.344. So, 10095 miles per second times 1609.344 is equal to 1.625 × 107 meters per second.

When a suspension of algae is incubated in a flask in the presence of light and CO2 and then transferred to the dark, the reduct
Aloiza [94]

Answer:

The photosynthesis process is interrupted.

Explanation:

Algae produce energy using the photosynthesis process. The reduction of 3-phosphoglycerate to glyceraldehyde 3-phosphate is part of this process. Despite this reduction reaction being light-independent (Calvin Cycle), the precursors of this reaction are synthesized in light-dependent steps.

This is the reason why the reduction is blocked when the algae is placed in the dark.

Convert 18.9 moles to MgCl2 to formula units
Masja [62]

Answer:

18.9 moles of MgCl2 = 17.834 kg of MgCl2

Explanation:

The molecular weight of MgCl is 80.0 g/mol . So, to convert the given mole amount to grams, multiply this by this number, which is constant for all compounds with a specific composition (mass fraction).

Considering the original question was in the context of chemistry, I wanted to make it seem formal and more educational too. Hopefully that worked!  

EDIT: Came up with some text around what happens inside cells that would have made it better if someone just had an issue converting units, but I doubt my answer will be accepted >.<
