Number of protons is equal to atomic number and as argon atomic number is equal to 18 it would have 18 protons.
So, your answer is 18
<em>Paper chromatography is especially useful in characterizing amino acids. The different amino acids move at differing rates on the paper because of differences in their R groups.</em>
I think it’s D I’m not sure .........
Answer:
1.26 x 10⁸pm³ and 1.26 x 10⁻²²cm³
Explanation: Calculating for a body centered cubic lattice, the formula is
3d²= 16r²
where d = edge length of unit cell
r=radius of atom
3d²= 16 x (217)²
3d²=753424
d²=251141.3
d= 501.1pm
volume of unit cell= d³= (501.1)³= 1.26 x 10⁸pm³
converting to cm³= 1.26 x 10⁸(10⁻¹²m)³
=1.26 x 10⁸(10⁻¹⁰cm)³ = 1.26 x 10⁻²²cm³
Answer:
12: This is decomposition because nitrogen triiodide is breaking apart.
13: This is double displacement because the elements in the compounds are "switching".
14: This is synthesis because the water and carbon dioxide are combining.
15: This is also synthesis because the hydrogen and oxygen are combining.
16: This is single displacement because the sodium is "switching" the element it's bonding with.
