Answer:
lose potential energy and gain kinetic energy
Explanation:
trust me thats the right answer i am not goo at explanations
The atom that is made up of two protons is He. The number of neutrons is also two. The number of electrons matters in the charge. So to make 10 electrons, we add 8 more. hence, 4/2 He 8-.
Do this
3.35mol HCl | 34.46g HCl
------------------------------------
1 | 1mol HCl
Multiply all the numbers on top by all the numbers on bottom.
Answer:
The mass of CH4 is 60, 29 grams.
Explanation:
We use the weight of the atoms C and H for calculate the molar mass:
Weight of CH4= weight C+ 4 x weight H= 12,01 g/mol +4 x 1,008g/mol=
Weight of CH4 =16, 042 g/mol
1molCH4-----16, 042grams
3,758 mol CH4--X= (3,758 mol CH4 x 16, 042 grams)/1 mol CH4=60,285836 grams
