Answer:
PpN₂ = 0.326 atm
Explanation:
In this case, let's write the equilibrium reaction taking place here:
2NH₃(g) <------> 3H₂(g) + N₂(g)
Now, we know that when the reaction reach the equilibrium the partial pressure of H₂ is 0.978 atm, so, let's write an ICE chart and see what's happening here:
2NH₃(g) <------> 3H₂(g) + N₂(g)
i) y 0 0
c) -2x +3x x
e) y-2x 3x x
At the beggining we just have the sample of NH₃, we don't know how much but we don't need that data to get the partial pressure. In equilibrium, its produced hydrogen and nitrogen, and we know how much of hydrogen was produced, so, with that we can solve for the value of the partial pressure of NO by a simple math operation:
PpH₂ = 0.978 atm = 3x
PpN₂ = x
PpN₂ = PpH₂ / 3
PpN₂ = 0.978 / 3
<h2>
PpN₂ = 0.326 atm</h2>
Hope this helps
Answer:non-polar covalent compounds
Explanation:
In chemistry, like compounds interact. If a solvent is covalent and nonpolar, it will also dissolve nonpolar covalent compounds. This is because, they contain similar patterns of intermolecular interaction. Hence compounds that posses the same kind of intermolecular interaction can form a solution.
Answer:
Chemical reactions that absorb (or use) energy overall are called endothermic. In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products.
Answer:
40.7 kPa
Explanation:
P1 • V1 = P2 • V2
so...
98.8 kPa(p1) • 21.7 mL (v1) = P2 (we don’t know it) • 52.7 mL (v2)
Now you have to solve for P2 which is pressure, so just like an algebra equation, to get P2 by it self, you have to divide 52.7 mL from it.
(98.8 kPa • 21.7 mL) / 52.7 mL = P2
so...
P2= 40.7 kPa
