Atoms (Sodium and Fluorine)
Explanation:
On the whole, the metals burn in oxygen to form a simple metal oxide. Beryllium is reluctant to burn unless it is in the form of dust or powder. Beryllium has a very strong (but very thin) layer of beryllium oxide on its surface, and this prevents any new oxygen getting at the underlying beryllium to react with it
<span>Yes, each ATP molecule aids in moving 3 Na+ across the membrane.
so 150 </span>sodium ions are transported across the cell membrane when <span>50 ATP molecules are spent.</span>
Answer: The mass in grams is 514.8.
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number of particles.
To calculate the number of moles, we use the equation:
given molecules =
Putting in the values we get:
mass of
The mass in grams is 514.8.
The reaction ratio of hydrogen to the ammonia produced is 3:2 hence if 3 moles of hydrogen produce 2 moles of ammonia thus mathematically,
3moleH2=2mole NH3
5moleH2=?
Thus cross-multiplying
(5*2)/3= 3⅓ moles.
