Because if all the trees and grasslands are to disappear and turn into deserts then there would be no oxygen for us
Answer:
-41. 47
Explanation:
m = q / Cp x T
m = Mass
q = Energy (or joules)
Cp = Heat Capacity
T = Change in Temperature
Water's heat capacity is always 4.18.
This is the formula you'll need for change in temperature:
Final - Initial
So, 33 - 78 = -45
m = 7800 / 4.18 x -45
= -41.47
The compound is sodium chloride
6.21 x 10^3 = (Move decimal point 3 spaces to the right)
6210
6210 (0.1050)
