1.what did magnesium and oxygen atoms had to do to bond ?
devlian [24]

Answer:

1. Magnesium and oxygen atoms bond to form an ionic compound; this is evident because one forms a cation and the other an anion. When an ionic compound is formed, one atom "steals" an electron (or electrons) from another. In this case, an oxygen atom (which is pretty electronegative by the way) "steals" 2 electrons from a magnesium atom. The resulting oxygen anion and magnesium cation attract one another to form a bond (more specifically, an ionic one).

2. The oxygen atom needed two sodium atoms to bond because it needs two additional electrons to achieve a stable octet of electrons. 1 sodium atom provides 1 additional electron after it is "stolen" by oxygen, so 2 sodium atoms are needed in total to form the bond.

3. The magnesium atom needed two fluorine atoms to bond because it needs to lose two electrons to achieve a stable configuration/octet of electrons. 1 fluorine atom "steals" one electron, so 2 are needed in total.

Happy Holidays!

g Classify the statements as describing deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). DNA RNA is a single molecule that
zmey [24]

Answer:

DNA:

- is a single molecule that can be over 10,000,000 nucleotides long

- is usually double stranded  

- includes the base thymine

- is the genome for prokaryotic organisms

RNA:

- can be translated into a protein  

- is usually single stranded  

- includes ribose sugar  

- is a single molecule that can form a complex secondary structure

Explanation:

Deoxyribonucleic acid (DNA) is the hereditary genetic material of both prokaryotic and eukaryotic organisms, while RNA is the genetic material of many viruses. DNA is a double helix molecule composed of four types of nucleotides: a nitrogenous base (Adenine, Thymine, Cytosine and Guanine), a five-carbon sugar (i.e., deoxyribose), and a phosphate group. On the other hand, RNA is usually a single-stranded molecule whose nucleotides contain ribose sugars and Uracil bases replace Thymine bases. During translation, a type of RNA molecule referred to as messenger RNA (mRNA) is used as template to direct the synthesis of a polypeptide chain (protein). This RNA molecule can fold to form stable double-stranded RNA hairpins (i.e., secondary structures).

Matthew has discovered a new species of fish. During the summer months, the male fish separate themselves from the female fish a
IgorC [24]
D should be the answer as they are no longer able to perform sexual reproduction without the other fish. Therefore, they would die off because they have lost the partner needed to reproduce.

Hope this helps!
