Cu2S is the one that is going to form a precipitate and Cu(NO3)2 will not form a precipitate because it is soluble. It is a fact that those that are insoluble will form a precipitate. I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
The correct option is this: THE KEQ IS SMALL AND THE REACTANT ARE FAVOURED.
Since we are told in the question that the reaction give rise to only 10% product, this means that much product are not been produced, thus the reactants are favoured. Keq stands for the equilibrium constant of the reaction and it measures the rate at which the reactants are converted to products. For this reaction, the equilibrium constant is small and the backward reaction [reactant] is favoured.
Answer:
<u>1.0 M</u> of KCl
Explanation:
First off, we're given 6.0 g of KCl. From here, we just find the molar mass of KCl by adding the molar masses of each element in the compound. The molar mass for the potassium is 39 g/mol, and the chlorine is 34 g/mol (all found on periodic table). We add those to find the compounds molar mass, which turns out to be 73 grams/ mole.
From here, we need to convert grams to moles so we multiply the grams by the molar mass so that we cancel out grams and only leave behind moles ( 6.0 grams x 1 mole/73 grams ≈ <u>0.08 moles</u>).
From here, we need to find the amount of liters in the solution, considering that the Molarity (M) is the same equation as mol/ Liter. To find this, we must convert similar units so that they work, in this case, we must convert milliliters to liters. We know that 1000 milliliters are equal to 1 liter, therefore like what we did with the molar mass and grams, we must cancel out milliliter so we only have liters ( 80 mL x 1 L / 1000 mL= <u>0.08 L</u>)
From here, we divide the moles by the liters in order to make the molarity. The reason why is because as said before, M is equal to mol/L
(0.08 moles / 0.08 L = 1.0 M)
I hope this helped you and good luck with your semester in Chemistry!
Answer:
Accleration is how long it took to get to speed. Constant speed is where you are already move at a steady speed.
