Answer:
+3
Explanation:
The oxidation number of a specie is the charge that it appears to have as determined by some arbitrary rules.
If we look at the reaction, we will notice that arsenic is more electro positive than chlorine so it is likely to function as the reducing agent in the reaction, loosing three electrons to have an oxidation number of +3 in the product.
Properties change within a Row (or period) as the number of valence electrons in the outer shell increase
Answer:
- The condensation reaction that forms nucleic acid polymers occurs between a <u><em>Phosphate</em></u> group on one nucleotide and a <u><em>hydroxyl group of sugar</em></u> on a second nucleotide.
Explanation:
- When nucleotides polymerize to form nucleic acids, the hydroxyl group attached to the 3′ carbon of a sugar of one nucleotide forms an ester bond to the phosphate of another nucleotide, eliminating a molecule of water.
Summary:
So the phosphate group of one nucleotide form bond with the hydroxyl group of an other nucleotide with the elimination of water molecules.
<u>Answer</u>:
This describes primary succession.
<u>Explanation</u>:
In the case of primary succession, the sequence of communities is formed in lifeless habitat. With the formation of the new ecosystem, life evolves gradually. In retreating glacier’s case, the new land is being revealed on its receding.
During the initial stage, the land is void of soil and vegetation. This leads to micro-organisms to breakdown the bedrock and soil formation starts. With the efficient amount of soil creation the new vegetation starts.
Answer:
Homogeneous solution
Explanation:
The salt and water dissolve to give a clear solution I.e without crystals.
