Trava [24]

net ionic equation:

SO₄²⁻ (aq) + Ba²⁺ (aq) → BaSO₄ (s)

Explanation:

We have the following chemical reaction:

H₂SO₄ (aq) + Ba(OH)₂ (aq) → BaSO₄ (s) + 2 H₂O (l)

Now we write the ionic equation:

2 H⁺ (aq) + SO₄²⁻ (aq) + Ba²⁺ (aq) + 2 OH⁻ (aq) → BaSO₄ (s) + 2 H⁺ + 2 OH⁻ (aq)

We remove the spectator ions to obtain the net ionic equation:

SO₄²⁻ (aq) + Ba²⁺ (aq) → BaSO₄ (s)

where we have:

(aq) - aqueous

(s) - solid

(l) - liquid

Consider the given acid ionization constants. identify the strongest conjugate base. acid ka hf(aq) 3.5×10−4 hc7h5o2(aq) 6.5×10−
vfiekz [6]

higher Ka value= stronger acid

stronger acids have weaker conjugate bases, so the acid with the strongest conjugate base would be acetic acid

Searches related to If 0.75 grams of iron (Fe) react according to the following reaction, how many grams of copper (Cu) will be
jolli1 [7]

Answer:

0.83 g

Explanation:

Step 1: Write the balanced equation

Fe + CuSO₄ ⇒ Cu + FeSO₄

Step 2: Calculate the moles corresponding to 0.75 g of Fe

The molar mass of Fe is 55.85 g/mol.

0.75g \times \frac{1mol}{55.85g} = 0.013 mol

Step 3: Calculate the moles of Cu produced from 0.013 moles of Fe

The molar ratio of Fe to Cu is 1:1. The moles of Cu produced are 1/1 × 0.013 mol = 0.013 mol.

Step 4: Calculate the mass corresponding to 0.013 moles of Cu

The molar mass of Cu is 63.55 g/mol.

0.013mol \times \frac{63.55g}{mol} = 0.83 g

Chromium (VI) forms two different oxyanions, the orange dichromate ion, Cr2o72-, And the yellow chromate ion, CrO4 2-. The equil
MrRissso [65]

Answer:

See explanation

Explanation:

Let us look at the reaction again;

Cr2O7 2- (aq) + H2O(l)⇄ 2CrO4 2-(aq) + 2H^+(aq)

When we add sodium hydroxide to the system as shown, the hydroxide ion removes the hydrogen ion thereby leaving a large concentration CrO4^2-(aq) in the system this causes the solution to turn green(equilibrium position shifts to the right).

The net ionic equation is;

OH^-(aq) + H^+(aq) ----> H2O(l)

The reaction;

OH^-(aq) + H^+(aq) ----> H2O(l) is exothermic hence, if the temperature of the system is increased, the equilibrium position will shift towards the left hand side and the solution turns orange.
