1- A calculation that determines how much greenhouse has an individual generates
2-physical processes in chemical reactions that move carbon through the biosphere and geosphere
3-and overall increase in the worlds temperatures attributed to increased concentrations of greenhouse gases
4-components of air mixture that trap infrared energy
5- rain water that has a pH lower than normal
I think this is right,
Hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm maybe
From the chemical eqn
No of moles of N2O5 = Mass/ molar mass
Molar mass = (14* 2) + (16 *5) = 28 + 90 = 118g.
From the chemical equation 7.9g of NO2 reacts with 7.9 *2 g of N2O5. We have a 1 :2 mole ratio. Hence mass of N2O5 = 14.8g
No of moles = 14.8/ 118 = 0.133 moles.
Answer:
-3.4 m
Explanation:
The displacement is the difference between the final position and the initial position:
4.4 m - 7.8 m = -3.4 m
It is not possible to find a vector quantity of magnitude zero but components different from zero
The magnitude can never be less than the magnitude of any of its components
