<h3>
Explanation:</h3>
<u>Step 1: Define</u>
[RxN] 4HCl (g) + 6NO (g) → 5N₂ (g) + 6H₂O (g)
[Given] 404.87 g HCl
<u>Step 2: Identify Conversions</u>
[RxN] 4 mol HCl = 5 mol N₂
Molar Mass of H - 1.01 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of HCl - 1.01 + 35.45 = 36.46 g/mol
Molar Mass of N - 14.01 g/mol
Molar Mass of N₂ - 2(14.01) = 28.02 g/mol
<u>Step 3: Stoichiometry</u>
<u />
= 388.935 g N₂
<u>Step 4: Check</u>
<em>We are given 5 sig figs. Follow sig fig rules and round.</em>
388.935 g N₂ ≈ 388.94 g N₂
1. Planetary Winds:
The winds blowing throughout the year from one latitude to another in response to latitudinal differences in air pressure are called “planetary or prevailing winds”. They involve large areas of the globe.
4. Periodic Winds:
Periodic winds change their direction periodically with the change in season, e.g., Monsoons, Land and Sea Breezes, Mountain and Valley Breezes.
Answer:
Condense and explode.
Explanation:
matter from the space can condense to form a nebula or matter from a star can explode to form a nebula.
Answer:
chlorine atom
A chlorine atom has 17 protons, 18 neutrons, and 17 electrons.
Explanation:
If you mean m (subscript l) is (-2,-1,0,1,2)
its a 3d orbital so it can hold 2 electrons, however, like in an electron diagram a 3d orbital has 5 boxes can can hold 2 electrons that is how i got 10 total but if you mean just in box 2 then only 2 can share it.
Does that make sense?
