Answer:
Q = ne
Explanation:
Ler n be the number of electrons transferred and Q be the charge of an ion.
The net charge on the object is then given by :
Q = ne
Where
e is the electronic charge
Hence, the charge of an ion relates to the number of electrons transferred is equal to Q = ne.
Answer:
b. 0.47 moles Ca.
Explanation:
Hello there!
In this case, since 1 mole of any element contains 6.022x10²³ atoms of the same, it is possible for us to compute the moles in 2.8x10²³ atoms of calcium via the Avogadro's number:

Therefore, the answer would be b. 0.47 moles Ca.
Best regards!
Answer:
Explanation:
For the reaction: 2X + 3Y = 3Z, the combination of 2.00 moles of X with 2.00
moles of Y produces 1.75 moles of Z
2 mol 2 mol 1.75 mol
2X + 3Y = 3Z
need 2 mol 3 mol to give 3 mol
3 mol Z/3 mol Y= 1 to 1
should get 2 mol Z
1.75/2 =87.5 % yield
