The answer is false. The particles in a suspension are not dissolved into the solvent rather they are suspended or dispersed into the solvent, Suspension is a heterogeneous mixture where solute-like particles settle out of a solvent-like phase. Examples are mercury in shake in oil, oil shake in water, and chalk in water.
Answer:
1. 2.17 dm^3
2. 109.1 dm^3
3. 0.398 atm
Explanation:
1. Considering the equation of the reaction;
Number of moles of chlorine gas in 3.44 g= 3.44/2(35.5)= 0.0485 moles
Since we can see from the equation that
1 mole of chlorine gas yields 2(22.4) dm^3 of HCl
0.0485 moles of chlorine gas yields 0.0485 moles × 2(22.4)dm^3/1= 2.17 dm^3
2. Note that 1 mole of Kr occupies 22.4 dm^3
Therefore 4.87 moles of Kr will occupy 4.87 × 22.4 dm^3/1 = 109.1 dm^3
3. From PV= nRT
n= 0.0485 moles
V= 4.55 L
T= 455 K
P= the unknown
R= 0.082 atm dm^3K-1mol-1
P= nRT/V
P= 0.0485 moles × 0.082 atm dm^3K-1mol-1 × 455/4.55
P= 0.398 atm
<span>The wick merely transports some of the liquid up to where vaporizes.It is not part of reaction but it does affect the reaction rate greatly,so it is a sort of catalyst in that time.if you wrap the wick in the aluminum it will block the transport the wax and it will wither go out less or brightly</span>
Taken from a dictionary: "in any undisturbed sequence of rocks deposited in layers, the youngest layer is on top and the oldest on bottom, each layer being younger than the one beneath it and older than the one above it."
The answer is C because I kno
