Transition metals are the metal located in the center block of the periodic table. Also, this block represents the D sublevel.
So, the answer is 3d.
Also, keep in mind that the D block starts "one period late". this means that if you are in period 4, the 3d orbital starts. if you are in period 5, that where 4d starts.
A solution of a pH of 4 has 10 times the concentrations of H+ present compared to a solution with a pH of 5, where;
pH = - log [H+], the concentration of H+ of pH=4 is:
[H+] = anti Log (- pH) = 10 ^ - pH = 10 ^ - 4 = 0.0001 M >>>>> (1)
the concentration of H+ of pH = 5 is
10^ -5 = 0.00001 M >>>>> (2)
So, (1) more than (2) by 10 times
All chemical reactions either give off or absorb energy.
How to solve 20.0 mL/ 5.7 g with significant figures and including units?
Answer:
Hope this Helps!!
The formula for density is the mass of an object divided by its volume. In equation form, that's d = m/v , where d is the density, m is the mass and v is the volume of the object. The standard units are kg/m³.
