Answer:
A) Neutral.
Explanation:
Protons are positively charged and electrons are negatively charged, while neutrons have no charge. In a "neutral atom", the number of protons must be equal to the number of electrons, otherwise it would not be neutral.
Hope this helps! :)

Answer:
27oz
Explanation:
Let the volume quantity of the 10% solution = x
The volume quantity of the 15% alcohol solution is known as = 18oz
Therefore the volume of the 12% product = 18oz + x
Therefore
0.10 × x + 0.15 × 18oz = 0.12 × (18oz+x)
0.15×18oz - 0.12×18oz = 0.12×x - 0.10×x
.
0.03*18oz = 0.02x
Dividing both sides by 0.02
x = 27oz
Verifying the answer, we have
0.1 × 27 + 18 × 0.15 = 0.12 × 45
2.7 + 2.7 = 5.4
Answer: The correct answer is option A.
Explanation:
There are 2 types of nuclear reactions:
1. Nuclear fission reaction: In this type of reaction, a heavier nuclei splits into two or more lighter nuclei. This process releases neutrons and further split additional atoms, generating into chain reactions.
where, A is heavier nuclei and B & C are lighter nuclei.
2. Nuclear fusion reactions: In this type, two lighter nuclei combines to form a single heavier nuclei.
where, A & B are lighter nuclei and C is a heavier nuclei.
In the given question, a heavier nuclei is splitting into two nuclei and releasing neutrons which are further splitting the two nuclei obtained into more nuclei. Hence, this is considered as a chain reaction which is caused by the splitting of nuclei or nuclear fission reaction.
Hence, the correct answer is Option A.
