Low potential energy means there are fewer chemical bonds so H2O has Less than C6H12O6 because their are less valence electrons making bonds with others. in an endothermic reaction heat goes into the product so the reactants would have less potential energy.
Answer:
that tornado frequency has increased over a large swath of the U.S. Midwest, Southeast and parts of the Ohio Valley. tornado activity has decreased in portions of the central and southern Great Plains – parts of Texas, Oklahoma and northeast Colorado – a region traditionally associated with Tornado Alley.
Explanation:
Hope this helps have a wonderful day
I think it may be “past climate of Earth seen in glaciers”/ I learned about this and that one doesn’t really ring a bell, plus it doesn’t make sense to me. I four sure know it’s not the fitting like a puzzle one. Sorry if I get this wrong.
Answer:
The partial pressure of nitrogen is 597.5 torr
Explanation:
Step 1: Data given
Mol fraction of N = 0.781
Mol fraction of O = 0.209
Mol fraction Ar = 0.010
Atmospheric pressure = 765.0 torr
The partial pressure is given by Pi = Xi * Pt
⇒ χ
i = the mole fraction of gas i in the mixture
⇒ P
total = the total pressure of the mixture
Step 2: Calculate the partial pressure of nitrogen
P(N) = mol fraction of N * atmospheric pressure
P(N) = 0.781 * 765.0 torr = 597.5 torr
The partial pressure of nitrogen is 597.5 torr
