Answer:
1.26 g of Cu
Explanation:
Since we have to find the percentage of the given amount so...
Yield in grams = (Initial mass used / 100) x Percentage Yield
Yield in grams = (1.57 / 100) x 80.6 = 1.26 g of Cu
Answer:
H2O = (1×2) + ( 1×16)
2+ 16
= 18
<u>22.9</u>
18
1.27
I don't know this answer is right or wrong.
so please ask it from your another friend.
The correct answer is B(OH)3 <AI(OH)3 < In(OH)3.
The metallic character of the group 1 elements first increases from Boron to Aluminium, then decreases from Aluminium to Thallium because of high ionization Enthalpy. Also, the larger size of the ion, the lesser is the ionization of Enthalpy.
Basic nature of the hydroxides of group 13 increases on moving down the group as the electro-positive character of elements increases.
Therefore, the correct order of increasing aqueous basicity is as follows:
B(OH)3 <AI(OH)3 < In(OH)3
What is the basic nature of group 13?
The metallic charecter of the elements affects their fundamental characteristics. The basicity rises as the metallic character does, and vice versa. Therefore, as we move lower in any given group, the atomic radius of the elements increases. Higher radii indicate that it would become increasingly challenging for the nucleus to rule over the electrons in the valency shell. Consequently, there will be a greater inclination for electron release. As a result, the metallic properties will improve, increasing the basicity of the oxides. Therefore, it follows that the basicity of the oxides would rise as we go down in a group.
