Answer:
I don't really get the options but it favoures the reactant side.
Explanation:
Increasing pressure favours the side with fewer moles of gas while decreasing pressure favours the side with the more moles of gas. E.g
If there is 0 moles of gas particles in the reactant side and 1 mole of gas particle in the product side, increasing pressure favours the reactants while decreasing pressure favours the product side.
With the explanations I have made, I hope the question is now clear to you.
I believe that east Texas is shaded green because it either has a grassy plain or there are a lot of grassy hills and I think that west Texas is shaded brown because it is like a desert.
Mass of N₂ will be formed : 50.12 g
<h3>Further explanation</h3>
Reaction
2 NH₃(g) + 3 CuO(s) → N₂(g) + 3 Cu(s) + 3 H₂O(g)
moles NH₃ = 3.58
ratio mol NH₃ : mol N₂ = 2 : 1
so mol N₂ :
mass N₂ (MW=28 g/mol) :
Answer:
3.96 × 10⁻³ mol Pb
Explanation:
Step 1: Find molar mass
Pb (Lead) - 207.2 g/mol
Step 2: Use Dimensional Analysis
= 0.003962 mol Pb
Step 3: Simplify
We have 3 sig figs
0.003962 mol Pb ≈ 0.00396 mol Pb
0.00396 mol Pb = 3.96 × 10⁻³ mol Pb
<u>Answer:</u>
photoelectric effect and the modifications to the Rutherford model is necessary
<u>Explanation:</u>
Photoelectric effect refers to emission of electrons when a light of certain frequency falls into a metal surface or a metal atom.
Rutherford, through his alpha particle scattering experiment, proposed the emission of electrons, in which he used a thin gold foil and high energy alpha particle were directed to the foil. He suggested that any light can emit electron from any metal surface.
