Answer:

A

Explanation:

because the species being oxidized shares electrons with the species that is reduced.making the oxidized element positively charged and the reduced element negatively charged.

Write the dissociation equation for, and give the proper concentrations for a 0.25M K2SO4 solution
weeeeeb [17]

Answer: K_2SO_4\rightarrow 2K^++SO_4^{2-}

concentration of K^+  = 0.50 M

concentration of  SO_4^{2-} = 0.25 M

Explanation:

The dissociation equation of K_2SO_4 is:

K_2SO_4\rightarrow 2K^++SO_4^{2-}

According to stoichiometry:

1 mole of K_2SO_4 gives 2 moles of K^+

Thus 0.25 moles of K_2SO_4 gives =\frac{2}{1}\times 0.25=0.50 moles of K^+

Similarly,

1 mole of K_2SO_4 gives = 1 mole of SO_4^{2-}

Thus 0.25 moles of K_2SO_4 gives =\frac{1}{1}\times 0.25=0.25 moles of SO_4^{2-}

Thus the concentration of K^+ and SO_4^{2-} are 0.50 M and 0.25 M respectively.

Many electrophilic aromatic halogenations require the presence of aluminum trihalide (halide-chloride or bromide) as a catalyst.
mixas84 [53]

Answer: The aluminium trihalide assists in the heterolytic bond fission of the bromine molecule.

Explanation:

The electrophilic aromatic bromination of acetalinide with molecular bromine requires the formation of Br+. This specie is formed when an Aluminum trihalide reacts with bromine. The Br-Br bond breaks heterolytically such that charged species are produced. This Br+ participates in the electrophilic aromatic substitution and AlX4- is formed where X4 shows a tetrahalide complex of aluminium

Describe two ways nitrogen gas is changed into forms that living things<br> can use
Misha Larkins [42]

There are three ways nitrogen can be fixed to be useful for living things: Biologically: Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants.

Hope this helps!
