Answer:
macro-evolution
Explanation:
This happens when evolution occurs because of separation of a population.
11.412 x 10^23.
EXPLANATION:
5.5 oz = 155.92 g
155.92 g x (1 mol/82.2 g) = 1.8956 mol
(6.02 x 10^23) x 1.8956 = 11.412 x 10^23
Answer:
Do to half of the mnairals this can not be made into a lab there is an error
Explanation:
Answer and Explanation:
The IUPAC substitutive name of the major product when 2-methylbut-1-ene reacts are as follows
a) HCl = 2-chloro-2-methylbutane
b) HBr in the presence of peroxides = 1-bromo-2-methylbutane
c) H2O/ H2SO4 (dilute sulfuric acid) = 2-methylbutane-1,2-diol
d)BH3-THF followed by basic hydrogen peroxide = 2-methylbutan-1-ol
e) Chlorine in water = 2-chloro-2-methylbut -1 -ol
f) Bromine in carbon tetrachloride = 1,2- dibromo-2-methybutane
g) H2 in the presence of a metal catalys = isopentane or 2- methyl butane
A chemical compound can be described as substance composed of atoms from more than one element held together by chemical bonds in a fixed stoichiometric proportion. A compound has different physical and chemical properties from its constituent elements.
For example : compound water is made up of H and O bonded together and it has different properties from O and H.
Thus, among the given options, the one coreectly describing a compound is
a) The atoms are bonded together, and the compound has different physical and chemical properties than the individual elements.
