Answer:
10moles
Explanation:
mole ratio = 8:16
therefore
1 mole Li2S forms 2 moles Li
when 5 moles Li2S reacts
5 moles Li2S = 5 x 2 moles Li
= 10 moles Li
An increase in temperature increases the average kinetic energy of molecules.
When the temperature of a molecule increases, the molecule starts to move at a faster rate. The faster a molecule moves, the more kinetic energy it has.
The muscles will contract and work together to contract in different ways
* Answer: 448.056 meters *
——
1 yard = .9144 meters (according to Google)
100 yards= 91.44 meters
——
100*4.9= 490 yards
490 yards = 448.056 meters
* 4.9 Football fields= 448.056 meters *
I hope this helps! :)
Answer: The theoretical yield and percent yield for this experiment are 40 g and 82% respectively.
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.
To calculate the moles:
According to stochiometry:
2 moles of produce = 2 moles of
0.54 moles of should produce = of
Thus theoretical yield is
But Experimental yield is 33 g.
The theoretical yield and percent yield for this experiment are 40 g and 82% respectively.
