The answer to your question is dependent variable.
Answer:
Explanation:
Number of moles of propane:
=Mass in grams ÷ Relative molecular Mass
= 100/((12*3) + (1*8))
= 100 ÷ 44
= 2.2727
Mole ratio propane:carbon (IV) oxide = 1:3(from the equation)
Number of moles of CO2 = 3*2.2727 = 6.8181
Mass in grams = Relative molecular Mass * Number of moles
= 44 * 6.8181
= 299.9964 grams

<h3>What the KWL chart?</h3>
The KWL chart is a perfect model that could assist the student in the learning of science. In this model, the student has to note down what he/she already knows about the experiment that is going to be performed. The notes in another column the wonders that he/she hopes to unravel during the course of the experiment and in the last column the student has to fill what he/she has learned after the experiment.
Having said that, if I want to leant about water, I already know that the molecules of water are in constant random motion according to the kinetic molecular theory so I write that down.
Secondly, I wonder how these water molecules actually move. If i drop a pollen grain i water and observe the zigzag motion of the pollen grain due to the bombardment of the water molecules, I can now write that I have learnt that the molecules of water move in a zig zag manner.

The answer of this question is Oxygen
Answer:
Since Q > Ksp, a precipitate of AgCl will form.
Explanation:
Step 1: Data given
Molarity AgNO3 = 0.10 M
Molarity of NaCl = 0.075 M
Ksp AgCl = 1.77 * 10^-10
Step 2: The balanced equation
AgNO3 + NaCl → AgCl(s) + NaNO3(aq)
For 0.10 moles AgNO3 we have 0.10 moles Ag+ ( molarity = 0.10 M)
For 0.075 moles NaCl we have 0.075 moles Cl- (molarity = 0.075 M)
Step 3: Calculate Q
Q = [Ag+][Cl-]
Q = (0.10 M )(0.075 M ) = 0.0075
Ksp = 1.77 * 10^-10
Q >>> Ksp
Since Q > Ksp, a precipitate of AgCl will form.
