Answer:
Explanation:
% yield = (actual yield / theoretical yield) X 100
For this question,
% yield = (150g/ 162 g) X 100 = 92.6%
Answer:
19 protons, 20 neutrons and 18 electrons.
Explanation:
Answer:
To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest
The Arrhenius Theory
The Brönsted-Lowry Theory
The Lewis Theory
(let me know if needed explanation)
Due to the cation forms a precipitate by adding H₂S in presence of HCl so this cation must be from group II cations
The choices provided for this question are: Ca²⁺, Mn²⁺, Zn²⁺ and Cd²⁺
So the correct answer will be cadmium since it is the only cation from choices that present in group II cations
If you have other choices you can choose any member of group II cations and divalent like Cu²⁺ , Hg²⁺
