Answer:
D
Explanation:
With there being more things (and technically more surface area) more organisms can hid in the little crevasses.
Percent abundance - biggest percentage. relative abundance- percent composition of organisms. you will get both the percentages of percent and relative abundances.
D. It has mass, takes up space, and can be seen without a microscope.
Answer:
In the n = 3 energy level
Explanation:
There's is no further explanation for this.
All the electrons in an energy level are distribuited according to the period in the periodic table they are.
So, if we have an atom in period 1, like Hydrogen (H), that atom would only have 1 level energy (n = 1) and in that level, we only have the sub level 1s.
Electrons in the 3d sublevel, are found mostly in all the transition metals of period 3, and it can go from 1 to 10 electrons. To be with the 3d sub level it's neccesary that the energy level to be 3.
energy levels beyond that, like n = 4, we have electrons occupying the 3d sub level, so, primordly, the 3d is found only in energy level 3.
Hope this helps
Molar mass of C_3H_6 = 36 g mol^-1 +6g mol^-1 =42g mol^-1
Empirical formula of Sample = (CH_3)
Explanation:
Mass sample having only C and H = 42g
Mass of C = 12g mol^-1
Molar mass of C = 12g mol^-1
Moles of C = 36 g / 12g mol^-1
= 3 mol
Mass of H in sample = 6g
Molar mass of H = 1 g mol^-1
Moles of H = 6g / 1g mol^-1
= 6 mol
Therefore in 42g sample 3 mol of C + 6 mol of H present, that is C_3H_6
Molar mass of C_3H_6 = 36 g mol^-1 +6g mol^-1 =42g mol^-1
Empirical formula of Sample = (CH_3)
