Explanation:

The net ionic equation of a reaction is obtained from the complete ionic equation after removing the spectator ions.

The balanced chemical equation for the reaction of sodium bicarbonate with acetic acid is shown below:

NaHCO_3(aq)+CH_3COOH(aq)->CH_3COONa(aq)+H_2O(l)+CO_2(g)

The complete ionic equation is:

Na^+(aq)+HCO_3^-(aq)+CH_3COO^-(aq)+H^+(aq)->CH_3COO^-(aq)+Na^+(aq)+H_2O(l)+CO_2(g)

The net ionic equation is:

HCO_3^-(aq)+H^+(aq)->H_2O(l)+CO_2(g)

Answer:The net ionic equation is shown below:

HCO_3^-(aq)+H^+(aq)->H_2O(l)+CO_2(g)

Part i. you considered the equilibrium: fe3+(aq) + scn-(aq) fe(scn)2+(aq), and compared the color of the solutions in four test
Alexus [3.1K]

Answer:

The equilibrium will be shifted to lift with the formation of a brown gelatinous precipitate of Fe(OH)₃.

Explanation:

  • Le Chatelier's principle states that <em>"when any system at equilibrium for is subjected to change in concentration, temperature, volume, or pressure, then the system readjusts itself to counteract the effect of the applied change and a new equilibrium is established that is different from the old equilibrium"</em>.
  • The addition of NaOH will result in the formation of Fe(OH)₃ precipitate which has a brown gelatinous precipitate.
  • The formation of this precipitate cause removal and decrease of Fe³⁺ ions.
  • According to Le Chatelier's principle, the system will be shifted to lift to increase Fe³⁺ concentration and reduce the stress of Fe³⁺ removal and readjust the equilibrium again. So, the [Fe(SCN)²⁺] decreases.
  • Increasing [Fe³⁺] will produce a yellow color solution that contains a brown gelatinous precipitate of Fe(OH)₃.

Answer:

<h3>The answer is 8.29 %</h3>

Explanation:

The percentage error of a certain measurement can be found by using the formula

P(\%) =  \frac{error}{actual \:  \: number}  \times 100\% \\

From the question

actual density = 19.30g/L

error = 20.9 - 19.3 = 1.6

We have

p(\%) =  \frac{1.6}{19.3}  \times 100 \\  = 8.290155440...

We have the final answer as

<h3>8.29 %</h3>

Hope this helps you
