It is an indicator of overall ozone layer health, and since satellites always monitor the Earth's atmosphere, its not terribly expensive.
Answer:
Copper Atoms
Explanation:
All copper atoms have atomic number 29: all their nuclei contain 29 protons. But they also contain uncharged particles called neutrons. In natural copper, the atoms are of two kinds. One has 29 protons and 34 neutrons in the nucleus; the other has 29 protons and 36 neutrons
Answer:
m = 57.581 g
Explanation:
The actual yield or experimental yield of a reaction is always calculated using the theorical yield and the experimental, using the following expression:
%yield = Exp yield/theo yield * 100 (1)
If we know the theorical yield and the percent of yield, we can calculate the experimental or actual yield by solving the expression above:
Exp yield = %yield * theo yield/100
Replacing the values we have:
Exp yield = 81.1 * 71 / 100
Exp yield = 57.581 g
And this would be the actual yield of the reaction
