Answer:
Explanation:
The answer is (4) 4.0 mol. This is a stoichiometry problem. You start with 2.0 mol of C2H6 and obtain the moles of C by multiplying 2.0 by the mole ratio, in this case 2. 2.0*2=4.0mol.
Answer:
2.0 g Na
Explanation:
Stoichiometry.
8.4g sodium hydrogen citrate x (1 mol sodium hydrogen citrate / 192 g sodium hydrogen citrate) x (2 mol Na/1 mol sodium hydrogen citrate) x (23g Na/1 mol Na)
^write it out it makes more sense that way
The attractive force that occurs between the sun and the earth is called:
Gravity
This force works to keep everything on the planet grounded.
