Answer:

Explanation:

According to Arrhenius Acid-Base Theory, acids are those substances that dissolved in water divide generating H⁺ together with an anion (ion with negative charge). In an aqueous solution, H⁺ protons immediately react with water molecules to form H₃O⁺ hydronium ions. A base, on the contrary, according to this theory, is a substance that liberates OH⁻ ions in aqueous solution.

This theory is valid only in aqueous medium.

You know: NH₃(g) + H₂O(l) → NH₄⁺(aq) + OH⁻(aq)

In this case, the water dissociates with the formation of hydrogen ions, H⁺, which NH₃ accepts to form the NH₄⁺ ion. So the water acts as an acid.

On the other hand, in reaction:

NH₄⁺(aq) + OH⁻(aq) → NH₃(g) + H₂O(l)

NH₄⁺ dissociates with the formation of hydrogen ions, H⁺, which water accepts to form the H₃O⁺ ion. So NH₄⁺ acts as an acid.

For reaction: NH₃(g<span>) + </span>H₂O(l<span>) → </span>NH₄⁺(aq<span>) + </span>OH⁻(aq), water (H₂O) is donor of proton (H⁺) and ammonia (NH₃) is acceptor of proton (base).
For reaction: NH₄⁺(aq) + OH⁻(aq) → NH₃(g) + H₂O(l) , NH₄⁺ is acid (donor of proton (H⁺)) and hydroxy anion (OH⁻) is base (acceptor of proton).
According to  Bronsted-Lowry theory acid are donor of protons and bases are acceptors of protons (the hydrogen cation or H⁺<span>).</span>

How much heat will be given off when 1500 g of water cools down by 20 C? please help and explain:)))
docker41 [41]

Answer:

126000J

Explanation:

From the question given, we obtained the following information:

M = 1500g

C = 4.2J/g°C

ΔT = 20°C

Q =?

Q= MCΔT

Q = 1500 x 4.2 x 20 =

Q = 126000J

Consider the following equilibrium:
Ainat [17]

<u>Answer: </u>The equation which is wrong is K_p=K_c(RT)^{-5}

<u>Explanation:</u>

For the given reaction:

4Fe(s)+3O_2(g)\rightarrow 2Fe_2O_3(s)

The expression for K_c\text{ and }K_p is given by:

K_c=\frac{1}{[O_2]^3}

K_p=\frac{1}{[O_2]^3}

The concentration of solids are taken to be 1, only concentration of gases and liquid states are taken. The pressure of only gases are taken.

Relationship between K_p\text{ and }K_c is given by the expression:

K_p=K_c\times (RT)^{\Delta n_g}

where,

\Delta n_g= number of moles of gaseous products - number of moles of gaseous reactants

R = gas constant

T= temperature

For the above reaction,

\Delta n_g = number of moles of gaseous products - number of moles of gaseous reactants = 0 - 3 = -3

Hence, the expression for K_p is:

K_p=K_c\times (RT)^{-3}

Therefore, the equation which is wrong is K_p=K_c(RT)^{-5}
