Global warming
Carbon dioxide is released into the air, causing global warming.
Answer:
m = 19 grams
Explanation:
Given that,
No. of moles, n = 0.8
The molar mass of magnesium, M = 24.305 u
We need to find the mass of 0.80 moles of Mg. We know that given mass to the molar mass is equal to no of moles. Let the mass is m. So,
or
m = 19 grams
So, the mass of 0.8 moles of Mg is 19 grams.
Answer:
I think you can make 26, hope this helped.
Explanation:
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.
I think the answer is cation, and anion
