<u>Answer:</u> The equation is given below.
<u>Explanation:</u>
Single replacement reactions are the chemical reactions in which more reactive metal displaces a less reactive metal from its chemical reaction. General equation for these reactions is given by the equation:
Metal A is more reactive than metal B.
The reactivity of metals is judged with the help of reactivity series. In this series, the metals lying above are more reactive than the metals which lie below in the series.
For the reaction of solid lithium metal and nitric acid, the equation follows:
This is a type of single replacement reaction because Lithium (more reactive metal) is replacing Hydrogen (less reactive metal) from the chemical reaction.
Answer:
0.017 mol
Explanation:
CH3COOH - acetic acid - we can write as C2O2H4
From formula C2O2H4 we can see that ratio C: O = 2:2 = 1:1, so number of moles C and O are the same.
So if we have 0.017 mol C, we should have 0.017 mol O.
Answer: gravitational force
Why?: gravity will always <em>pull </em>and move things in this earth, even when it comes to projectiles, gravity will still be a major part in its movement. therefore, your answer would be gravitational force! i hope this helped you!
Answer:
43%
Explanation:
As the problem says that the antimony has only two isotopes, lets call each isotope the following:
x=abundance of isotope 121Sb
1-x=abundance of isotope 123Sb
And
Atomic weight of antimony = (isotopic mass of 121Sb*x)+(isotopic mass of 123Sb*(1-x))
Replacing values we have:
Solving for x:
it means that the abundance of the isotope 121Sb is 57% and the abundance of isotope 123Sb is 43%
