Answer:
A. 35Cl1-
Explanation:
Chlorine needs 1 more electron to have full octet thus will take 1 electron and possess a -1 charge.
Answer:
3.4 × 10^23 molecules
Explanation:
To find the number of molecules present in C6H14, we multiply the number of moles in the compound by Avagadro's number (6.02 × 10^23 atoms).
number of molecules = number of moles (mol) × 6.02 × 10^23?
Number of molecules = 0.565 × 6.02 × 10^23
3.4 × 10^23 molecules
Answer: microscope?
Explanation:
I'm not exactly sure it could even be an invension of some kind of test or experiment
V=0.650 L
c=0.505 mol/L
M(Na₂CO₃)=106.0 g/mol
the amount of substance of sodium carbonate is:
n(Na₂CO₃)=vc
the mass of sodium carbonate is:
m(Na₂CO₃)=n(Na₂CO₃)M(Na₂CO₃)
m(Na₂CO₃)=vcM(Na₂CO₃)
m(Na₂CO₃)=0.650*0.505*106.0=34.7945 g
