1) Hydrocarbon: CH3 - CH2 - CH2 - CH2 - CH3
2) Only single bonds => alkane => sufix ane
3) no substitutions
4) 5 carbons = > prefix penta.
Therefore, the name is pentane.
1 wavelength, 2 crest, 3 trough, 4 wave height <3
Explanation:
Anions and cations have different atomic sizes than the neutral atoms.
When the bromine atom becomes an anion, it ______ in size.
Anions involves gaining extra electrons. This basically leads to increased repulsion between the electrons and thereby increasing the size. Anions are always larger than the neutral atoms.
This means the answer is A. Increase
When the strontium atom becomes a cation, it ______ in size.
Cations involves losing valence electrons. This basically leads to a decrease in electron shells and electron repulsion thereby reducing the size. Cations are always larger than the neutral atoms.
This means the answer is B. Decrease
Answer:
0.125 mg
Explanation:
<em>The correct answer would be 0.125 mg</em>
<u>According to the conversion factor, one milligram of a sample is equivalent to one thousand micrograms of the same sample.</u>
milligram = 
microgram = 
Hence,
1 milligram = 1000 micrograms or 1 microgram = milligram
Therefore, 125 micrograms will be:
125/1000 = 0.125 milligram
