Ksp that is solubility product can be defined as ratio of product to the reactant . It is higher than 1 implies there are more products than that of reactants favoring forward direction reaction and as solubility product defines solubility so its higher value indicate that solid phase is relatively soluble, So High values of Ksp greater than 1.0 infer that solid phase is relatively soluble and also the chemical reaction proceeds readily to the right.

What is the molarity of the 8.76 g of Na2S dissolved in 0.500 L of solution?
AlexFokin [52]

Answer:

.224 M

Explanation:

To begin, we need to find the molar mass of Na2S

  • Na=22.99g, S=78.05g
  • 2(22.99)+1(32.07)=78.05

To find Molarity, we use the equation M=moles/Liters of solution

We are given grams, so we must divide by the molar mass of Na2S to find moles.

  • 8.76g Na2S / 78.05g/mol Na2S= .112 moles

Now we use our Molarity equation:

  • .112 moles Na2S / .500L of solution = .224 M

The polyatomic nitrate ion (NO3−) is present in both the products and the reactants of the chemical equation shown below.
Diano4ka-milaya [45]

Answer:

There is one nitrate ion in the products, and two in the reactants of this equation.

Explanation:

1: We know a nitrate ion has the formula NO_{3}^{- , so we just need to count how many of them are on each side of the equation.

2: To find how many are in the reactants of the equation, you look at the left hand side (before the arrow). You can see the section (NO_{3} )_{2} , which shows that there are two nitrate ions in the reactant side (as seen by the little 2).

3: To find how many are on the products side, you do the same thing - this time there is only one NO_{3}^{- in the lithium nitrate.

So, there is one nitrate ion in the products, and two in the reactants of this equation.

How many moles of lithium chloride will be formed by the reaction of chloride with 4.28 mol of lithium bromide in the following
lys-0071 [83]

Answer:

The answer is 4.28 moles

Explanation:

This is super easy okay, you won't forget this!

Basically mole ratios, we're just looking at the coefficients in front of the compounds, multiplying them, and dividing them as we see fit.

In this example, you can see how you need 2 moles of lithium bromide (LiBr) for the reaction, and 2 moles of lithium chloride (LiCl) will be produced.

Basically, the <u>molar ratio</u> is when you divide numbers and see how much of this do I have for that (if that makes sense).

So if you were to divide the 2 moles of LiBr / 2 moles of LiCl = 1. So we know that the mole ratio for LiBr to LiCl is 1:1 or 2:2, either or, it's the same thing.

SO THE BIG IDEA, if we have 4.28 moles of lithium bromide reacting, we should also have 4.28 moles of lithium chloride produced, BECAUSE the <u>mole ratio</u> is 1:1.

I hope this makes sense please tell me if it doesn't, I will try my best to explain a little more.
