Answer:
<h3>The answer is 78 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 10 cc
density = 7.8 g/cc
So we have
mass = 7.8 × 10
We have the final answer as
<h3>78 g</h3>
Hope this helps you
Answer:
4 tert-butylcyclohexane will have the higher Rf value when ethyl acetate is used as the developing solvent because the 4-tert-butylcyclohexanol is the more polar compound that can form hydrogen bonds with the polar silica gel stationary phase.
this means less polar 4-tert-butylcyclohexanol will have a higher Rf
Lowering the activation energy
Answer:
C. 0.50 mol
Explanation:
Number of mole= mass /molar mass
Mass of KF is given as 29g
The molar mass of KF= 39+19= 58g/mol
No of mole= mass/ molar mass
= 29g/58g/mol
1/2 mol= 0.5 mol
Answer:
Light
Explanation:
The discovery of light from the other side of a black hole was predicted by Einstein's theory of general relativity. ... The research began with a slightly different aim of a more common light formed by a black hole: the corona which wraps around the outside of it, formed as material falls in.
