Answer:
C. Carbon
Explanation:
Carbon has an electronegativity of 2.55, followed by Tin at 1.96, Silicon at 1.90 and the least electronegative would be Lead at 1.87.
Hey...
Use the molarity formula
M=moles/L and then convert to grams
0.07268*0.15=moles
<span>0.010902 mol
</span>Pb(NO3)2
1 mole=331.22g
0.010902 moles=
3.61 g
Answer:
Explanation:
1. Weight = 35 P and 45 N = 80
2. Atom: 35P = 35 electrons
3. Bromine
4. It's a non metal. It's in column 17. It will gain 1 electron (normally).
5. Ion: 35 protons, 36 electrons
6. Charge: - 1 usually, but there are exceptions
7. Anions go to the Anode. The anode attracts minus charged elements.
8. In an uncharged state, element 36 would be next. That would be Krypton which is always uncharged. It is a noble gas.
