Answer:
5.47 x 10^23 atoms in Ag (sliver)
Explanation:
0.909 mol of Ag x 6.02 x 10^23 atoms of Ag/ 1 mol of Ag
Answer:
Explanation:
Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.
Answer:
0.092 %
Explanation:
The equation of the reaction can be computed as :


recall that; the number of moles = 
By applying the method of enthalpy of combustion for sucrose at the same time changing the time from hours to seconds, we can determine the total energy output.
i.e


Given that the sun supplies about 1.0 kilowatt, to KJ/m² s, we have:

Finally, the percentage of sunlight used to produce sucrose :
= 
= 0.092 %
Atoms are combining to form molecules
