Answer:
True......................had to do this because we need atleast 20 letters
Th first one is Iron and the second one is Xenon
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:
8 neutrons and 6 electrons
Explanation:
Mass number= neutrons + protons
14=x+6
x=14-6
x=8
protons=electrons
6 protons=6 electrons
Well start by figuring the total amount of buns brought. This is found by multiplying the amount of packages brought by how many there were in each pack...
32 x 12 = 384
Now it says that you had 2 full packs left, and die extra buns. So you can figure how many are left with...
(2 x 12) + 5 = 29
Now subtract the total bins you had by how many you have left, and you'll see how many were used.
384 - 29 = 355
So 355 buns left, tell john he doesn't need so many! I hope this helps!
