A. Acid rainfall will cause a decrease in oceanic surface temperatures. O B. Increased atmospheric carbon dioxide will cause increased ocean surface temperatures.
O C. Any measurable increase in ocean surface temperatures must be caused by human activites.
OD. Saturation of nitrogen in the atmosphere will cause a wide range of ocean surface temperatures.
(PLEASE HELP ME)

Increased atmospheric carbon dioxide will cause increased ocean surface temperatures.

Explanation:

Greenhouse gases of which CO2 is a typical example are known to cause a gradual and steady increase in the surface temperature of the earth by trapping infrared rays close to the surface of the earth.

As the surface temperature of the earth rises, the surface temperature of the oceans rises also leading to the tendency towards hurricanes.

Hurricanes are violent storms which are known to form near the equator over warm ocean waters.

Hence, increased atmospheric carbon dioxide will cause increased ocean surface temperature which in turn increases the chances of the occurrence of hurricanes.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
