Answer:
The number of molecules is 3,01E23 of N2
Explanation:
We use the formula PV=nRT, and STP: 1 atm of pressure and 273 K of temperature.
PV=nRT ---> n=PV/RT
n= 1 atm x 11,2 l /0,082 l atm/ Kmol x 273K
n= 0, 5 mol
We use the number of Avogadro:
1 mol---------6, 02E23 molecules
0,5 mol----- x= (0,5 mol x6, 02E23 molecules)/ 1 mol = 3,01E23
Explanation:
cellular respiration is a process that occurs in the mitochondria of all organisms. In this process, both plants and animals break down simple sugars into carbon dioxide and water and release energy in the form of adenosine triphosphate (ATP)
An atomic mass is the sum of the protons and neutrons of a given element. The atomic mass is given it what is called a weighted average of all the different kinds of that element. Take carbon for example. It has carbon-12, carbon-13, and carbon-14. The reason its atomic weight is so close to 12 (12.011 ish) is because carbon-12 is by far the most common, and carbon-13 and -14 are so uncommon, that the weighted average is close to 12, but not exactly 12.
Answer is: adding NaCl will lower the freezing point of a solution. A solution (in this example solution of sodium chloride) freezes at a lower temperature than does the pure solvent (deionized water). The higher the solute concentration (sodium chloride), freezing point depression of the solution will be greater.
long term consequence, not many can come back from it
