I’m pretty sure it’s true
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.
Answer:
Chlorine
Explanation:
Even though chlorine is highly electronegative, the best answer is no, and in this class we will consider chlorine not to form hydrogen bonds (even though it has the same electronegativity as oxygen). This is because chlorine is large and its lone electron is in a diffuse orbital, covering a large area, and thus do not have the high charge density to act as a strong hydrogen bond acceptor. But it does form weak hydrogen bonds in solid crystalline hydrogen chloride at very low temperatures.
The answer is D because for light 3 to function switch d does not have to turn on
Answer:
1.175 M
Explanation:
Mass = 32.9 g
Volume = 700.0 mL = 0.7 L
Molarity = ?
The relationship between the quantities is given by;
Molarity = Number of moles / Volume
Number pf moles = Mass /Molar mass
Number of moles = 32.9 / 40 = 0.8225 mol
Molarity = 0.8225 / 0.7 = 1.175 M
