Answer:
A.0.20M
Explanation:
c 1 V 1 = c 2 V 2
Initial Volume, V1 = 200 mL
Final Volume, V2 = 200 + 400 = 600 mL
Initial Concentration, c1 = 0.60 M
Final Concentration, c2= ?
Solving for c2;
c2 = c1v1 / v2
c2 = 0.60 * 200 / 600
c2 = 0.20M
Answer:
B. LZAQD
A. Younger than A but older than Q
Explanation:
To solve this problem, we simply apply the stratigraphic laws which are the law of superposition and principle of cross cutting.
- According to the law of superposition, in an undeformed sequence of strata, the oldest layer is always at the bottom and the youngest on top.
- In this case, we have a little disturbance but it did not affect much of the original bedding.
- So, the rock ages from L to Z to A to Q and D. L is the oldest and D is the youngest.
According to the principle of cross-cutting "features that cuts through a rock are younger than the layers they cut through". In this problem, the fault cuts through layers LZ and A which suggests that these layers are older than the faulting event. Layer Q is unaffected by the faulting so, the fault is older than the layer.

The valence level of an atom refers to the number of electrons that reside in the upper most energy level. Nitrogen has an atomic number of 7 and therefore has 7 electrons. The first energy level (1) holds 2 electrons, leaving 5 electrons to reside in the second energy level (2s and 2p). Therefore the valence of nitrogen is 5.
Answer:
By dehydrogenation of cyclohexane you may get Benzene as a product. We may use noble metals(Au, Ag, Pt etc.) to dehydration of cyclohexane. Consider following reaction which gives an idea about reaction.
