-BARSIC- [3]

Reaction:

\mathrm{Mg \: + \: CuO \rightarrow Cu\: + \: MgO}

Magnesium is a stronger reducing agent than copper and is thus able to reduce copper(II) oxide.

Products of the reaction: Magnesium oxide and metallic copper.

When calculating the equilibrium constant, aqueous solutes must be expressed in moles per liter (M), and gases must be expressed
alukav5142 [94]

Answer:

B. They are dimensionless ratios of the actual concentration or pressure divided by standard state concentration, which is 1 M for solutions and 1 bar for gases.

Explanation:

Activity of a substance is defined as the ratio of an effective concentration or an effective pressure to a standard state pressure or a standard state pressure. It is usually a unit less ratio.

Concentrations in an equilibrium constant are really dimensionless ratios of actual concentrations divided by standard state concentrations. Since standard states are 1 M for solutes, 1 bar for gases, and pure substances for solids and liquids, these are the units to be used.

Hence, activity is a fudge factor to ideal solutions that correct the true concentration. Activity of a gas and solute concentration is a ratio with no unit.

Elements in group 16 want to bond with elements in group ___.
Trava [24]

Answer:

Two

Explanation:

Elements in group 16 wants to bond with elements in group IIA, the group of alkaline earth metals.

  • The bonding will make it easier for them complete their octet.
  • Elements in group 16 has 6 valence electrons.
  • To have a complete octet, they require 2 more electrons.
  • Group II elements are willing donors as they are metals.
  • For Group II elements to fill their octets, they must lose two electrons.
  • So the willingness of group II elements to lose two electrons and the readiness for group 16 elements to gain the electrons makes the desire one another.

Examine the general structure of a molecule.
Lilit [14]

Answer:

Explanation:

functional groups are specific substituents or atoms within molecules that brings about chemical reactions of those molecules. There is the same or similar chemical reaction in compounds with the same functional groups.

1.)The functional group in Alkyl halides is halogen atom whille

The functional group in Alcohols have

is OH group. There is a double bond in HX or an HOH molecules.

2.)The functional group of carboxylic acid is an organic compound is carboxyl functional group.While The functional group in amine contains a basic nitrogen atom with a lone pair of electrons.

3.)The functional group in ester is a carboxylic acid derivative that is analogous to the Amides

4.) A carboxylic acid has carboxyl functional group. However the hydrogen of the hydroxyl group is can be ionized. In an ester, there is a replacement of hydrogen of acarboxylic acid group by an alkyl group
