An ionic bond will most likely form
covalent bonds form when an electron is shared and ionic bonds form when an electron is transferred
Answer:
Explanation:
4)6.27x10^20/(6.02x10^23)(u should have this number on your formula sheet)=0.001 mol
5)7.4x6.02x10^23=44.548x10^23atoms
6)molar mass for K is 39.10g/mol
3.27x39.10=127.86g
Im bad at sig figs. Just do it urself(:p
If the final concentration of NOBr = 0.250M
Change in concentration of NOBr = +0.250 M
Change in concentration of NO = -0.250 M
Change is concentration of Br2 = -0.125 M ( since number of moles of Br2 is 0.5 times the number of mole of NOBr)
Final concentration of NO = 0.400-0.250 = 0.150 M
Final concentration of Br2 = 0.245 - 0.125 M = 0.0120 M
Therefore;
Kc = conc (NOBr)^2/ ((conc NO)^2 ×(conc (Br2)
= (0.250²)/(0.150²×0.120)
= 23.148
= 23.1 mol/dm³
Answer:
a item dropping
Explanation:
KE is movement and PE is height. As it's falling it gets KE and falls downward giving it more KE and less PE
From electronic configuration valence electron of Nitrogen is 5, oxygen 6x2 which 12 since it involve two molecules , that of is frulorine is 7, and that No2F is 24 which is gotten form adding (5,12,7 ).All resonance structure are as follows
