Answer: Single replacement Reaction
Explanation:
A replacement reaction is a chemical reaction in which an element replaces another element in a compound especially when it is more reactive than the former. There are two types of replacement reaction, the single and double replacement reaction.
In the former, one element which is usually more reactive than the other replaces it . For example in the single replacement, a more reactive metal replaces a less reactive metal and also a more reactive non metal can replace a less reactive non metal.
A + BC → B + AC
looking at the equation aove, you can see that B replaces A
Also In double replacement, the elements in the both reacting compounds are replaced or exchanged to form new compounds as can be illustrated in the equation
AB + CD —— AC + BD
In the case of Coach Kwan, she follows the Single replacement model as she substitutes a less active and tired player with an active one.
Answer:
has higher boiling point
Explanation:
has higher boiling point because in , has a very strong dipole and we know that whenever there is dipole-dipole interaction then boiling point increases. On the other hand in the NO group has not so strong dipole which weakens its boiling point
So the boiling point of is higher than the boiling point of
Answer:
7.36
Explanation:
my teacher said that was the right answer
Answer: (c)
Explanation:
Nuclear fusion reactions involve 2 smaller nuclides combining to form one larger nuclide.
However, the mass is not correctly balanced for (a), but it is for (c).
