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.

Calculate the following:
Brrunno [24]

Follow these steps to solve the given equation:

Multiply the two decimal figures together and find the sum of the exponents, that is,

(1.5 * 1.89) * 10 ^4+3

(2.835) * 10^7

10^7 can also be written as e.70

'e' stands for exponential. 

Therefore, we have  2. 835 e 7.0 = 2.8 e 7.0.

Based on the calculations above, the correct option is A.

"sodium hydroxide is a strong base because it absorbs more" ____________ ions than weak bases.
Hunter-Best [27]
The answer is: absorbs more H (protons) ions.

- The Sodium hydroxide NaOH ionizes completely when dissolved in water.
- For every mole of sodium hydroxide that you dissolve you get 1 mole of hydroxide anions.

Given the following table, which statement is true about atoms A and B?
lisabon 2012 [21]

Answer:

The statement true is A. A and B are isotopes of the same element.

Explanation:

Isotopes correspond to atoms of the same element with different mass numbers (A), that is to say they differ in the amount of neutrons in the nucleus. In the case of compound A it has 10 neutrons, and B has 11.
