Answer:
V= 48L
Explanation:
Moles of N2 = m/M = 30/28= 1.07moles
From the equation of reaction
N2 +3H2 → 2NH3
1mole of N2 produces 2mole of NH3
Hence
1.07moles will produce 1.07×2= 2.14 moles
At STP, 1mole occupy 22.4L
Hence volume of N2 produced = 2.14×22.4= 48 L
Hello there!
The correct answer is Ag⁺.
If we look at the solubility rules, it says that most chlorides are soluble, <u>except</u><em> </em>with Ag⁺, and Pb²⁺.
I hope this helps!

Answer: 94.07%
Explanation:
Percentage yield can be calculated by the formula
%yield = Experimental yield/Theoretical yield x100
Experimental yield = 7.93g
Theoretical yield = 8.43
%yield = Experimental yield/Theoretical yield x100
%yield = 7.93/8.43 x 100 = 94.07%
Answer:
a
Explanation:
magma is lava and lava is magma
The electrons fill energy levels from the lowest available energy level, based of three typical rules.
1) Follow Aufbau rule: fill from lower to higher energy levels (1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p)
2) Pauly exclusion principle: two electrons can not have the same four quantum numbers
3) Hund rule: if the orbitals have the same energy, the electrons must go to different orbitals before two occupies the same orbital.
