D, the energy of formation is equal to the dissociation. so from magnesium ions and Hydrogen ions, when they form the lattice energy is equal to formation-dissociation, as they aren't going to dissociate (fixed in lattice) the formation should be the same as the the overall lattice energy.

Answer:

0.84kg of gatorade powder

Explanation:

From the question given, we were told that 0.6kg of gatorade powder required 5 gallons of water.

To obtain the mass of gatorade needed for 7 gallons of water, we simply do the following:

0.6kg of gatorade powder required 5 gallons of water.

Therefore, xkg of gatorade powder will require 7 gallons of water i.e

xkg of gatorade powder = (0.6 x 7)/5

xkg of gatorade powder = 0.84kg

Therefore, 0.84kg of gatorade powder will be required.

Consider the reaction and its equilibrium constant at 25.0 ∘C :
olga55 [171]

Since Qp>Kp , the reaction is not at equilibrium.

<h3>What is the equilibrium constant?</h3>

The equilibrium constant shows the extent to which reactants are converted into products.

Now we have to obtain the Qp as follows;

Qp =[CH3OH]/[CO] [H2]^2

Qp = 0.265/(0.265) (0.265)^2

Qp = 14.2

Now we know that Kp = 6.09×10−3, Since Qp>Kp , the reaction is not at equilibrium.

There are 342 g of sucrose in 1.00 mol of sucrose. What is the molar concentration (molarity) of a solution containing 171 g suc
andrezito [222]
Given the values above, in order to know the molar concentration or the molarity of a solution containing 171 g of sucrose in 1.25L solution, here is the solution that you should follow: So,
MM = 342 (g/mol) 
171 (g) / 342(g/mol) = x mol of sucrose 
<span>x moles of sucrose/ 1.25 L =  Molarity of solution
</span>Hope this is the answer that you are looking for.
