Answer:
B.
Explanation:
Buffer has equal concentrations of A- and HA.
B. when [F -] is equal to [HF]
Answer:
<em>the <u>valency of an element</u> is its combining capacity that is the number of electrons it requires to lose, gain or share in order to become neutral.</em>
[ An element can become neutral if it completes it's octet. That is if an element has 8 electrons in it'd outermost shell then it is considered neutral ]
- The valence of Magnesium is 2 because it requires to lose 2 electrons to become neutral.
- whereas, the valence of Oxygen is 2 because it needs to gain 2 electrons to become stable.
Hence they both have the same valence.
One may say that oxygen's valence is -2 while that of Magnesium is + 2. It's meaning is still the same but "-" sign indicates that oxygen will be gaining electrons in the process of becoming stable.
B
While nuclear energy does not pollute the environment, it poses the risk of radiation which is harmful to organisms because it causes lethal mutations.
Explanation:
Nuclear fission, for example, releases neutrons and other particles (at very high speeds) that can ionize materials including DNA. This will induce mutations of DNA most of which are usually lethal to organisms. Gamma and X- rays are also produced by fusion reactions and if exposed to organisms also cause mutations on DNA through double stranded breaks. Therefore, the risk of an accident of a nuclear reactor can have immense ramifications on the ecosystems.
