Answer:

The final molarity of chloride anion in the solution is 0 molar.

Explanation:

Mass of potassium chloride solution = 1.88 g

Moles of potassium chloride = \frac{1.88 g}{74.5 g/mol}=0.02524 mol

Moles of silver nitrate = n

Molarity of silver nitrate solution = M= 23.0 M

Volume of the silver nitrate solution ,V= 300.0 mL = 0.3 L

moles(n)=Molarity(M)\times Volume (L)

n=23.0 M\times 0.3 L = 6.9 mol

AgNO_3(aq)+KCl(aq)\rightarrow AgCl(s)+KNO_3(aq)

According to reaction 1 mol of potassium nitrate reacts with 1 mol of silver nitrate .

Then 0.02524 moles of potassium chloride will react with:

\frac{1}{1}\times 0.02524 mol=0.02524 mol of silver nitrate.

As we can see that potassium chloride is in limiting amount due to which the potassium chloride will get completely converted into silver chloride and potassium nitrate.

Since , no potassium chloride will left after reaction which indicates that no chloride ions will be present after reaction.

[Cl^-]=0 M

The final molarity of chloride anion in the solution is 0 molar.

Given the following equation, how many grams of PbCO3 will dissolve when exactly 1.0 L of 1.00 M H+ is added to 6.00 g of PbCO3?
9966 [12]
Calculating for the moles of H+
1.0 L x (1.00 mole / 1 L ) = 1 mole H+

From the given balanced equation, we can use the stoichiometric ratio to solve for the moles of PbCO3:
1 mole H+ x (1 mole PbCO3 / 2 moles H+) = 0.5 moles PbCO3

Converting the moles of PbCO3 to grams using the molecular weight of PbCO3
0.5 moles PbCO3 x (267 g PbCO3 / 1 mole PbCO3) = 84.5 g PbCO3

The gasses in a hair spray can are at temperature 300k and a pressure of 30 atm, it
Sergeeva-Olga [200]

Answer:

900 K

Explanation:

Recall the ideal gas law:

\displaystyle PV = nRT

Because only pressure and temperature is changing, we can rearrange the equation as follows:
\displaystyle \frac{P}{T} = \frac{nR}{V}

The right-hand side stays constant. Therefore:

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

The can explodes at a pressure of 90 atm. The current temperature and pressure is 300 K and 30 atm, respectively.

Substitute and solve for <em>T</em>₂:

\displaystyle \begin{aligned} \frac{(30\text{ atm})}{(300\text{ K})} & = \frac{(90\text{ atm})}{T_2} \\ \\ T_2 & = 900\text{ K}\end{aligned}

Hence, the temperature must be reach 900 K.

2Al+3Cl2⟶2AlCl3
Leviafan [203]

Answer:

7.335 moles of  Cl₂ are required to react with 4.89 miles of Al.

Explanation:

Given data:

Moles of Al = 4.89 mol

Number of moles of Cl₂ required = ?

Solution:

Chemical equation:

2Al + 3Cl₂    →   2AlCl₃

Now we will compare the moles of Al and chlorine from balance chemical equation.

                            Al           :         Cl₂

                             2           :           3

                            4.89      :         3/2×4.89 =7.335 mol

Thus, 7.335 moles of  Cl₂ are required to react with 4.89 miles of Al.
