Answer:
I'm pretty sure its h bonding. however I could very welp see it being Van der Waals
<span>Mol is the unit of amount of substance. It is equal to 6.02 x 10^23 molecules. Now, One mol of Sodium chloride (NaCl) contains 6.022x 10^23 molecules of NaCl. Also, the number atoms of both Na (sodium) and Cl (chlorine) will be equal. Similatly, One mol of Aluminium Chloride (AlCl3) contains 6.022x 10^23 molecules of (AlCl3) but the ratio of Al and Cl atoms will be 1:3</span>
Oxygen because it is on the left of the periodic table so it has a strong pull.
Answer:
potassium.
Explanation:
located at start of period 3, will have larger radius
<span>1.54 x 10^5 mg
The atomic weight of nickel is 58.6934
Since you have 2.63 moles, the mass will be
2.63 * 58.6934 = 154.3636 grams.
Multiply by 1000 to get milligrams
154.3636 * 1000 = 154363.6 g
Convert to scientific notation
1.543636 x 10^5
Look at the available options and see what matches.
3.56 x 10^5 mg ; Nope, way too big
1.54 x 10^5 mg; Matches to the number of significant figures given.
2.23 x 10^4 mg; Nope, way too small
129 mg; Nope, way too small.</span>
