Answer:
About 7.9 L.
Explanation:
We can utilize the ideal gas law. Recall that:
Because the amount of carbon dioxide does not change, we can rearrange to formula to:
Because the right-hand side stays constant, we have that:
Hence substitute initial values and known final values:
Therefore, the final volume is about 7.9 L.
37.8 g CH2Br2 X (1 mol CH2Br2 / 173.83 g) = 4.60X10^-3 mol CH2Br2
<span>4.60X10^-3 mol CH2Br2 X (2 mol Br / 1 mol CH2Br2) X 6.02X10^23 atoms/mol = 5.54X10^21 bromine atoms.
I think this is the answer.</span>
Answer:
The early atmosphere
Its early atmosphere was probably formed from the gases given out by volcanoes. It is believed that there was intense volcanic activity for the first billion years of the Earth's existence. The early atmosphere was probably mostly carbon dioxide, with little or no oxygen.

Answer:
the air molecules from the cookies diffused faster than the air molecules from the pumpkin
Explanation:
The smell of cookies reaches first because the air molecules from the cookies were able to diffuse faster than the air molecules from the pumpkin.
<em>At constant temperature, the diffusion rates of two molecules would be dependent on the size of the molecules. The bigger the size of the molecule, the more time it will take for the molecule to diffuse and vice versa. </em>
Thus, <u>since the pumpkin and the cookies were baked at the same temperature, the smell of the cookies was perceived first because the air molecules of the cookies are smaller in size than the air molecules of the pumpkin.</u>
Answer:
Saccharose
Explanation:
Disaccharide Saccharose is formed by glucose and fructose, both monosaccharides are bound by their anomeric carbons (O-glucosidic), this is, both reducing carbons form the O-glucosidic bond, hence, they are not available to reduce Ag⁺ to Ag⁰
