Is 8Ag2S → 16Ag + 1S8 a single replacement

1 answer:

4 0

No it’s a decomposition reaction
Explanation:
Hint- look where the arrow is
If there is 1 product with an arrow next to it, then it is a decomposition reaction
This shows a product decomposing (breaking down) into 2 elements, which is a decomposition reaction

What is the molarity of a solution that is made by mixing 35.5 g of Ba(OH)2 in 325 ml of solution?

choli [55]

Answer:

$M=0.638M$

Explanation:

Hello!

In this case, since the molarity of a solution is calculated by diving the moles of solute by the volume of solution in liters, we first compute the moles of barium hydroxide in 35.5 g as shown below:

$n=35.5g Ba(OH)_2*\frac{1molBa(OH)_2}{171.34gBa(OH)_2}\\\\n=0.207mol$
