Kinetic energy id energy of motion and is equal to 1/2mv^2 where m = mass and v = velocity.
So the answer is a salmon leaping up a waterfall.
The solution for this problem is:
Look for the moles of NaOH which is 0.0385 L x 0.150 M = 0.00578
H3PO4 + 3 NaOH = Na3PO4 + 3 H2O
moles H3PO4 = 0.00578 / 3 = 0.00193
M of H3PO4 = 0.00193 mol / 0.0150 L= 0.128 is the molality we are looking for in this problem.
Answer:
82.28g
Explanation:
Given parameters:
Number of moles of hydrogen gas = 7.26 moles
Unknown:
Amount of ammonia produced = ?
Solution:
We have to write the balanced equation first.
N₂ + 3H₂ → 2NH₃
Now, we work from the known to the unknown;
3 moles of H₂ will produce 2 moles of NH₃
7.26 mole of H₂ will produce
= 4.84 moles of NH₃
Molar mass of NH₃ = 14 + 3(1) = 17g/mol
Mass of NH₃ = number of moles x molar mass = 4.84 x 17 = 82.28g
