Explanation: The earth was one a big ocean but than volcanoes explode and that created land :)
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.

The answer is D because the order of l to g is Planet, Solar System, Galaxy and then Universe
Answer:
the first one
Explanation:
neutrons only have neutral charges and electrons are not heavier than protons
Answer:
Explanation:
People make and use alloys because metals don't have exactly the right properties for a job. usually, alloys are stronger and harder than their main metals, harder to work and less ductile (harder to pull into wires).
