The formula equation that shows a reversible reaction is

NH4Cl (s) ⇔ NH3 (g) + HCl (g) ( answer C)

Explanation

Reversible reaction is a chemical reaction where the reactants form products , where in turn react together to form reactant back.

The reaction of NH4Cl (s)⇔ NH3(g) + HCl (g) is a reversible reaction since NH4Cl decompose to form NH3 and HCl which in turn react together to form NH4Cl back .

tino4ka555 [31]

Answer:

$\%\ Composition\ of\ phosphorus=20.00\ \%$

Explanation:

The molecular formula of the monohydrate formed = $MgNH_4PO_4.H_2O$

The molecular mass of the monohydrate formed = $Mass_{Mg}+Mass_{N}+6\times Mass_{H}+5\times Mass_O$

So, Mass = 24 + 14 + 6 × 1 + 5 × 16 = 155 g

Mass of phosphorus = 31 g

Thus,

$\%\ Composition\ of\ phosphorus =\frac{Mass_{phosphorus}}{Total\ mass}\times 100$

$\%\ Composition\ of\ phosphorus=\frac{31}{155}\times 100$

$\%\ Composition\ of\ phosphorus=20.00\ \%$

What leads to the formation of an ionic bond with Hg2+?

statuscvo [17]

The attraction of an $SO_4^{2-}$ ion leads to the formation of an ionic bond with $Hg^{2+}$

<h3>What is an ionic bond?</h3>

Ionic bond, also called an electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.

Since the question asking among all these options:

(a) The attraction of a noble gas

(b) The attraction of a $NH^{4+}$ ion

(d) The attraction of a $SO_4^{2-}$ ion

An ionic bond can be formed after two or more atoms lose or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons.

Hence, option D is correct.

2. Determine the total pressure of a gas mixture that contains O2, N2, and He, if the partial

Burka [1]

Answer:

978mmHg

Explanation:

The total pressure of a gas mixture is defined as the sum of the pressure of each gas in the mixture.

If the mixture of gases you have 200mmHg for O₂, 350mmHg for N₂ and 428mmHg for He, total pressure of the mixture is:

200mmHg + 350mmHg + 428mmHg = 978mmHg
