Answer:
Distance lift the tree = 0.5 m
Explanation:
Given:
Work done = 50 joules
Force = 100 newton
Find:
Distance lift the tree
Computation:
Distance = Work done / Force
Distance = 50 / 100
Distance = 0.5 m
Distance lift the tree = 0.5 m
The atomic number 15 is p (phosphorus)
Answer: c
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.

Explanation:
Answer:
.234 M
Explanation:
Molarity, or concentration, of a substance is simply found by dividing the amount of that substance in moles by its volume. Here, we are given the mass (in grams) of Kool-Aid, so we need to convert that to moles. To do this, we simply need the chemical formula of Kool-Aid, which I have found to be C12H22O11. The molar mass of C12H22O11, using the periodic table, is 342.296 g. Next, take this molar mass and divide the given mass of Kool-Aid by it. You then get about .234 mol Kool-Aid.
Lastly, divide this by the volume of 1.0 L. You get .234 M as your final molarity.
