Which group of elements is characterized as having little to no reactivity?
C. <u>Alkali Metals</u>
The correct answer is exactly 750 g.
Since the mass of board is 750 g, the mass of the pile of sawdust after the whole board is ground down is 750 g.
This is according to the Law of conservation of mass. According to this law, matter can neither be created nor destroyed by any physical transformations or chemical reactions. In any chemical reaction the mass of the products is equal to the mass of the reactants.
Here the board undergoes a physical transformations from being a whole board to a pile of sawdust. Thus according to the Law of conservation of mass, the mass of the whole board will be equal to the mass of a pile of sawdust.
Before mRNA leaves the nucleus of a eukaryotic cell, a cap is added to one end of the molecule, a poly A tail is added to the other end, introns are removed, and exons are spliced together. During translation the amino acids are assembled into a protein.
<u>Given:</u>
Total Candium = 35
# of M&M = 15
# of Skittlitium = 12
# of Peanutttium = 8
<u>To determine:</u>
The relative abundance for each
<u>Explanation:</u>
Relative abundance = amount of each item in the sample/Sample total
M&M = 15/35 = 0.429 (or) 42.9 %
Skittlitium = 12/35 = 0.343 (or) 43.3 %
Peanuttium = 8/35 = 0.229 (0r) 22.9%
