If aqueous solutions of Na2SO4 and BaCl2 are mixed, does a precipitate form? If yes, identify the precipitate and the spectator

Sergeeva-Olga [200]

Answer:- A precipitate of $BaSO_4$ is formed and the spectator ions are $Na^+$ and $Cl^-$ .

Explanations:- A double replacement reaction takes place. In double replacement reaction, the ion exchange takes place and we write the products. Then we use the solubility chart to check if a precipitate forms.

The balanced molecular equation is:

$Na_2SO_4(aq)+BaCl_2(aq)\rightarrow 2NaCl(aq)+BaSO_4(s)$

From solubility chart barium sulfate is insoluble so its precipitate is formed. sodium and chlorine ions are spectator ions as shown in the below ionic equation.

$2Na^+(aq)+SO_4^-^2(aq)+Ba^+^2(aq)+2Cl^-(aq)\rightarrow 2Na^+(aq)+2Cl^-(aq)+BaSO_4(s)$

The net ionic equation is:

$SO_4^-^2(aq)+Ba^+^2(aq)\rightarrow BaSO_4(s)$

So, the spectator ions are $Na^+$ and $Cl^-$ and a precipitate of $BaSO_4$ is formed.

Lewis plot structure of Ca

Anna [14]

Answer:

Ca:

Explanation:

A Lewis structure shows the number of valence electrons about an atom.

Ca is in Group 2 of Period 4.

Its electron configuration is [Ar]4s².

Thus, Ca has two valence electrons and its Lewis structure is Ca:

A steel container filled with H₂ gas is at a pressure of 6.5 atm and a temperature of 22°C. If the container is placed near a fu

Yuki888 [10]

Answer: The new pressure is 7.1 atm

Explanation:

To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$
