The answer is A.The calcium atom must bond with an atom of high electronegativity (like fluorine) because the higher electronegativity atom will bully the low electronegativity atom and take away its electrons.
These are the choices:
A. an atom with a high electronegativity, like fluorine
B. another atom with a low electronegativity, like lithium
C. another atom that would like to share electrons
D. no other atoms because it's too weak to bond with anything
More nitrogen in the atmosphere leads to NITRIC ACID RAIN.
When nitrogenous fertilizers are used on the farm, some gases are released into the atmosphere including nitric oxide. These gases rises up into the atmosphere, mix with rainfall.
Nitric oxide react with rainfall to form nitric acid and it falls as acidic rain.
Answer:
Question 7:
C
Question 8:
C
Explanation:
Question 7:
If the pH number is smaller, the solution is more acidic. In turn, this means that it contains more H+ ions that OH- ions
Question 8:
A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution
Because they are not in charge of deciding the child's gender, males shouldn't accuse women of failing to deliver a male child for them. Everything is dependent on chromosomal fusion.
What is chromosol fusion?
Every now and then, chromosomes fuse. This fusion occurs as sperm and eggs develop, as pairs of chromosomes fold over each other and swap chunks of DNA. Sometimes two different chromosomes grab onto each other and then fail to separate. Scientists have observed both humans and mammals with fused chromosomes.
Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.
