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.
The answer is B red blood cells. The other three are part of our immune system to defense for infectious disease. While red blood cells are responsible for transport oxygen from lung to other place in our body.
C. Move one electron from sodium to fluorine, because the element with the smallest amount of valence electrons is the one that give away the electrons, it is easier to add one to seven than it is to add 7 to one. I just learned this in physics, hope it helps! If you need more explaining I can do that.
Answer:
mole ratio, which is equivalent to a 1;1 mole ratio, to a gram ratio. This means that when the reaction consumes 84.03 g of carbon monoxide, it should theoretically produce 132.03 g of carbon dioxide. Use this gram ratio to calculate the theoretical yield for your reaction.
