Helium is in group 18 of the periodic table. How is helium different from the other elements in this group? = Helium atoms have 2 valence electrons, while atoms of the other elements in the group all have 8 valence electrons.
An emission spectrum will occur when = An electron releases energy and falls back to a lower energy level.
Explanation:
Answer:
I'll give you the graphs that you need to look at:1st order: the graph you need to make is ln[A] vs t. If you get a straight line, the reaction is 1st order and the slope will equal to the rate constant K.2nd order: the graph you need to make is 1/ln[A] vs t. If this graph shows a straight line, the reaction is 2nd order and the slope will equal the rate constant K.
Explanation:
Answer:
1) km 2) cm^ 3) no units (kg cancels) 4) g/cm^3 5) g 6) g°C
Explanation:
Like units will cancel ((m/km)*(km) = m
Non-cancelled units remain (ml)*(g/ml)*(°C) = g°C
