Answer:
creat and trough are the parts of transverse wave
"Transition metal elements" are the type of element which have atomic radii which remain relatively constant across a period.
Periods refer to the horizontal lines of the periodic table. Each period represents the sequential occupation of an atom's valence shell orbitals, also with longer periods representing the employment of an atom's d subshell orbitals.
As the atomic number rises, more electrons, as well as protons, are present, increasing attraction over time, which drives the atomic radius to shrink over time.
Therefore, "Transition metal elements" are the type of element which have atomic radii which remain relatively constant across a period.

It shares the most properties with an element in its same row so it is Magnesium.
Hello, there can be multiple answers to the question you did not really put up a paragraph of the answers so here's a few...
1. you drive a car because fumes can release into the air
2. using any motorized thing releases fumes which can be dangerous
3. foundries the smoke that comes up keep pollution in the air
Hope this helps!!
Answer: 6.6 ml
Explanation:
If you had a 0.200 L solution containing 0.0140 M of Fe3+(aq), and you wished to add enough 1.27 M NaOH(aq) to precipitate all of the metal, what is the minimum amount of the NaOH(aq) solution you would need to add? Assume that the NaOH(aq) solution is the only source of OH−(aq) for the precipitation.
You have 0.014X0,2 = 0,0028 moles of Fe ion.
You need 0,0028 X 3 = 00084 moles of OH
The NaOH is 1.27 moles/liter
0.084/1.27 = 6.6 ml
