Answer: See attached image
Explanation:
The periodic table arranges elements in increasing
atomic number from left to right and top to bottom.
Horizontal rows on the periodic table are periods.
Elements in the same period have the same number of
electron shells.
Vertical columns on the periodic table are groups.
Elements in the same group have the same number of
valence electrons.
Answer:
28 g CO
Explanation:
First convert grams to moles.
1 mole C = 12.011 g (I'm just going to round to 12 for the sake of this problem)
12 g C •
= 1 mol C
1 mol O = 15.996 g (I'm just going to round to 16)
16 g O •
= 1 mol O
So the unbalanced equation is:
->
(the oxygen has a 2 subscript because it is part of HONClBrIF meaning when not in a compound these elements appear in pairs - called diatomic elements)
The balanced equation is:
-> 
However, carbon is the limiting reactant in this equation and two moles cannot react because only 12 g (1 mole) are present. Therefore, use the equation
->
.
1 mole of CO is formed, therefore 12 g + 16 g = 28 g CO.

Answer:
Calibration curves are used to understand the instrumental response to an analyte, and to predict the concentration of analyte in a sample.
