Answer:
v = 2.141 ml
Explanation:
we can use the "ideal gas law" :-
<h2> PV=nRT </h2>
p :- pressure ( pa )
V :- Volume ( m³ )
n :- amount of substance ( mol )
R :- Ideal gas constant ( 8.314 Jmol-¹ K-¹ )
T :- Temperature ( K)
Answer:
A. -10,000
Explanation:
When x approaches zero, the graph tells us that F(x) either becomes extremely large or extremely small. The best answer is therefore A: -10,000. Best, because we aren't given the exact value of x, but clearly the other results require that x be greater than 1 or less than -1, which is far from zero.
Answer:
Samples A and B are mixtures
Explanation:
For sample A, we were told that the initial density of the solution is 0.77/gmL. After distillation, the liquid left has a density of 1.04/gmL. Apparently, A is a mixture of liquids.
As for sample B, the spread of the chromatogram resulting in different colours show that the sample B is not pure. It is a mixture of substances. A pure sample will yield only a single spot.
Cl2 is the reduced substance
I believe the answer is B.
