Explanation:
We calculate the amount of carbon fixed as follows.

=
kg
= -1273.1 kJ/mol
= -393.5 kJ/mol
= -285.8 kJ/mol
Hence, total
reaction will be as follows.

= 
= 2802.7 kJ/mol
Therefore, calculate the number of moles of fixed carbon as follows.

= 
= 
Thus, we can conclude that the annual enthalpy change resulting from the photosynthetic carbon fixation over the land surface is
.
False, it is not the former President Bill Clinton. The United States of America President of the time when the Soviet Union was dissolved is no other than former President Geroge H. W. Bush. The Soviet Union started to dissolved way back in year 1980s but it was not yet former Presiden George H. W. Bush is the president that time, it was former President Ronald Reagan. On the year 1991, the Soviet Union finally dissolved and Bush was the president that time.
Answer:
1.10231×10-1 lb
Explanation:
we know that one gram is equal to the 0.00220462 lb or we can say that one pound is equal to the 453.592 g.
we have to convert the 50.0 g into pounds:
m (lb)= m(g)× 0.00220462
m(lb)=50×0.00220462
m(lb)=0.110231
in scientific notation:
1.10231×10-1 lb
Answer:Hummingbirds have long, needlelike beaks they use to probe deep into flowers. The hummingbird's beak is just a protective sheath for its tongue, which is actually what the hummingbird is using to get the nectar out of the flower. The tip of their tongue is forked and has little hairs all over it.
Explanation:
Tungsten and it is used in electric contact and arc wielding. I believe there are a few more uses.
