Which of these solutes raises the boiling point of water the most?

Raising of the boiling point is a colligative property. That means that it depends on the number of particles dissolved. The greater the number of particles the greater the increase in the boiling point. So, you can compare the effect of these solutes in the increase of the boiling point by writing the chemical equations and comparing the number of particles dissolved: 1)ionic lithium chloride, LiCl(s) --> Li(+) + Cl (-) => 2 ions; 2) ionic sodium chloride, NaCl(s) --> Na(+) + Cl(-) => 2 ions; 3) molecular sucrose, C12H22O11 (s) ---> C12H22O11(aq) => 1 molecule; 4) ionic phosphate, Na3PO4 --> 3Na(+) + PO4 (3-) => 4 ions; 5) ionic magnesium bromide, MgBr2 --> Mg(2+) + 2 Br(-) => 3 ions. So, ionic phosphate produces the greatest number of particles and it will cause the greatest increase of the boiling point.

An experiment was performed to determine how the amount of coffee grounds could affect the taste of coffee.The same kind of coff

gavmur [86]

What we want to measure is the taste of coffee.

The following were kept constant during the experimental investigation:
The type of coffee,
The type of percolator,
The same amount and type of water,
The same perking time,
The same electrical sources.

Because these items were kept constant, they are not expected to influence the outcome of the experimental investigation.

Define:
y = the metric used to measure the taste of coffee
x = amount of coffee grounds used for the taste experiment.

Therefore the relationship that arises from the experiment is
y = y(x).

Because x is controllable and is varied during the experiment, it is the independent variable.
Because the measured value of y depends on x, therefore y is the dependent variable.

Answer:
The taste of coffee is the dependent variable.
The amount of coffee grounds used is the independent variable.
