(3) nuclear fission
Hope I helped!
Answer:
The answer is in the explanation
Explanation:
Single displacement reactions: In these reactions, a more reactive element kicks out a less reactive element from a compound.
Ex. Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g)
In this example, Zn is more reactive than H, then Zn displaces H from the compound.
Double displacement reactions: In these kind of reactions 2 elements are displaced from the different compounds, these elements interchange positions.
Ex. CuCl2(aq) + 2 AgNO3(aq) → Cu(NO3)2(aq) + 2 AgCl(s)
In the example, Cu displaces Ag and Ag displaces Cu, they interchange positions.
Answer:
a and c that is 1st and 3rd statements are applicable to the given question
The molecular formula of quinine is C20H<span>24N2</span>O<span>2. For every 1 mole of quinine molecule, there are 20 moles of carbon. Simply multiplying 6.0 moles by 20, we get, 120 moles.
Therefore, there are 120 moles of carbon in 6.0 moles of quinine.</span>
Answer: Option (B) is the correct answer.
Explanation:
Metals are the substances that have more number of electrons. Metals are good conductors of heat and electricity.
For example, iron, copper, zinc are all metals and good conductors of heat and electricity.
Whereas wood and foam are is a poor conductor of heat and electricity.
Thus, we can conclude that out of the given options copper and iron are good conductors of heat.
