Answer:
B
Explanation:
A cation is a positively charged in. If an atom gives away an election, which is negatively charged, that would make it more positively charged, thus a cation.
Answer:
x = 0.45*28/3 = 4.2 g
Explanation:
showing work
N2 = 28 g/mole
3Mg + N2 → Mg3N2
3moles .. 28 g
0.45 moles .. x
x = 0.45*28/3 = 4.2 g (answer)
Hey there !
We know that
Atomic number , z = number of n+number of e
=> Z = 38+28 = 66
Hence the answer is B)Nickel-66
I hope this helps you:)
Have a good day ;)
Based on nuclear stability, the symbol for the most likely product nuclide obtained when nitrogen-13 undergoes decay is coming from the following equation:
₇N¹³ → Positron₊₁⁰ + ₆C¹³
So the correct answer will be ₆C¹³
I would say your answer is 22.4L
Hope that helps!!
have a wonderful day!!
