I believe the correct answer to this question is:
“Mixtures”
By definition, mixtures are combination of substances
which are not really chemically combined and hence separable by physical means.
There are two types of mixtures, homogeneous and heterogeneous, both are also
separable by physical means.
<span>This is as opposed to Compounds which are chemically
bonded and cannot be separated by physical means.</span>
Answer:
The hydrogen molecules combine with the oxygen molecules, 2 hydrogen molecules, and 1 oxygen molecules is the amount needed to make one water atom or molecule, whatever you want to call it.
The answer fam is.............This equation is balanced because there are 8 atoms of carbon (C), 26 atoms of oxygen (O), and 20 atoms of hydrogen (H) on each side of the equation.
ionic bond is formed when two oppositely charged ions attract one another.A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.
Answer:
a) 6.3 cm
b) 8.0 cm
c) 0.7875
Explanation:
(a) The compound has moved above upto 7.3 cm from the bottom of the paper. Let us assume that line is drawn at 1.0 cm mark as the origin of spot. \
Distance traversed by compound= 7.3 - 1.0 cm = 6.3 cm
(b) Distance traversed by the solvent = 9.0 - 1.0 cm = 8.0 cm
(c) The Rf = Compound Migration distance / Solvent front migration distance
= 6.3/8.0 = 0.7875
