Answer:
acid +base gives salt and water
acid and carbon gives salt and water and carbon dioxide
acid and metal gives salt and hydrogen
Answer:
6.32g
Explanation:
The mass of 1 mol of K is 40g, and the reaction needs 2 moles of K to produce 2 moles of KCl, so it needs 80g of K to produces 151g of KCl.
So you make a rule of three:
x = 3.35•151/80
x = 6.32g
Answer:
I think Acetone will be captured and cooled.
Explanation:
Distillation is a method of separation based on the difference in boiling point of two liquids.
The liquid that has a lower boiling point is first separated from the mixture. It vaporizes, cooled and collected before the liquid that has a higher boiling point.
In this case, acetone is captured and cooled before water since it has a boiling point of 56ºC and water has a boiling point of 100ºC.
Answer:
0.375mol/L
Explanation:
Well you were given the mole of solute (n) =0.133 and the volume of solvent (V) =355mL
Note that the molar Conc. also called Molarity = (n) the mole of solute/ (V) the volume of solvent
But keep in mind that the volume should always be in liter (L). Therefore, convert mL to L by dividing 1000:
V= 355mL/1000 = 0.355L
In the end, we apply the formula:
M = n/V
M= 0.133/0.355 = 0.3746mol/L ≈ 0.375mol/L
The total mass of heterogenous mixture is 183.68g
A combination is said to be heterogeneous if its composition is not constant throughout. A phase is any area of a sample with a consistent composition and set of characteristics. A heterogeneous mixture is one that has two or more phases by definition. When water and oil are combined, they do not mix equally but rather split into two layers.
A phase is the name given to each layer. Around us, there are a lot of heterogeneous mixtures. Different chemicals make up soil, and the composition might vary based on the sample that is obtained. The first shovelful might turn up soil and grass, while the second shovelful might come up with an earthworm. Another illustration of a heterogeneous combination is smog
The total mass of heterogenous mixture is = 139. 32 grams sand + 34. 99 grams gravel + 9. 372 grams salt.
The total mass = 139.32+34.99+9.372
The total mass = 183.68g
