Answer:
The new volume is 66.3 mL
Explanation:
Boyle's law states that pressure and volume are inversely proportional, and that P1V1=P2V2
P1 = 0.428 atm
P2=1.55 atm
V1 = 240 mL
V2 = ??
(0.428)(240)=(1.55)(V2)
102.72 = 1.55x
x = 102.72/1.55 = 66.27 mL.
By looking at the graph, you can determine the answer is C. Na2HAsO4 and Na2SO4.
Answer:
See explanation
Explanation:
The reaction to be considered is shown below;
H2CO3<------->CO2 + H2O
We know that when a constraint such as a sudden change in concentration, pressure or temperature is imposed on a reaction system in equilibrium, the system has to adjust itself by shifting in a particular direction in order to cancel the constraint.
Now, if we remove CO2, the equilibrium position must shift to the right by the decomposition of more H2CO3 to establish equilibrium again.
I think it’s c but I could be wrong
The last question depends on the scientific method.
Scientific Method
1. Make an observation of what u are testing 2. Form a question about ur observations. 3. Make a hypothesis 4. Conduct your experiment 5. Record information and results.
The first question depends what you will need to use first for the experiment.
