The Earth's gravitational force accelerates objects when they fall. It constantly pulls, and the objects constantly speed up.
Find the molar mass of CH3 and divide that by 45.0. That should give a whole number and then mult that whole number by CH3 to find molecular formula to get like ( incorrect ex: C2H6) which is mult by 2
Answer:
a
Explanation:
the solution is extremely acidic and will dissolve the zinc rod
Molar mass of N2 = 28
Moles of N2 = 25 / 28 = 0.89
So, moles of NH3 produce = 2 x 0.89 = 1.78
Note: H2 is in excess. so no need to care about it.
Quartz is a substance because the material has uniform properties throughout and is held together via chemical bonds.
