Answer:
14.5L
Explanation:
The following data were obtained from the question:
V1 = 14.1L
T1 = 13.9°C = 13.9 + 273 = 286.9K
T2 = 22°C = 22 + 273 = 295K
V2 =?
Using charles' law: V1/T1 = V2 /T2, we can obtain the new volume as follows:
14.1/286.9 = V2 /295
Cross multiply to express in linear form
286.9 x V2 = 14.1 x 295
Divide both side by 286.9
V2 = (14.1 x 295) / 286.9
V2 = 14.5L
Therefore, the new volume = 14.5L
The mass of 
is 0.185 g.
To calculate the number of moles first calculate the molar mass of .
Molar mass of nitrogen and oxygen is 14 g/mol and 16 g/mol respectively
Thus, 
Now, number of moles can be calculated from mass and molar mass as follows:
Therefore, number of moles of 0.185 g is 0.0042 mol.
Answer:
As a substance changes from a solid to a liquid to a gas, its molecules first the molecules are moving fast enough, they are able to "escape." They leave the surface of the liquid as gas molecules. Evaporation is not the only process that can change a substance from a liquid to a gas. The same change can occur through boiling.
Explanation:
hopfully this helps!
Yes mitochondria does make necrssary chemicals for the cell therefore the answer to your question is yes
Silicon has 14 protons Potassium has 19 electrons The neutrons are equal to the mass number minus the atomic number. Or the big number minus the small number on the periodic table. hydrogen 1 does not have a neutron.
iron =56 -26 for 30 neutrons in the nucleus
Chlorine 17 protons and 17 electrons. 18 or 19 neutrons on average.
