In addition, the dam was built during the second half of the 20th century as a government solution to the irrigation of the crop farms during droughts along the Nile River and recently provided electricity to the Nile region.
1) Chemical equation
2Al + 6 HCl ---> 2Al Cl3 + 3 H2
2) molar ratios
2 mol Al : 3 moles H2
3) Proportion
2 mol Al / 3mol H2 = x / 9 mol H2
4) Solve for x
x = 9 mol H2 * 2 mol Al / 3 mol H2 = 6 mol Ag
Answer: 6 moles
no
its kinematics
the acceleration due to gravity and the initial vertical velocity are the only thing that affects vertical distance
