Above it says the molecular weights are
NH3- 17g/mol and SF6-146 g/mol
Well 1 mole of SF6 is 146.048 grams (i added hte atomic masses of each element). So then the number of moles in 0.85 grams would be 0.00582000438 moles.
<span><span><span>= 1mole / </span><span>146.048g *</span></span> 0.85g</span>
so we would need 0.00582000438 moles of NH3 to have the same number of molecules.
One mole of NH3 is 17.030519999989988 grams (i added each atoms mass). so 0.00582000438 moles of NH3 would be:
<span><span><span>= 17.030519999989988 g / </span><span>mole * </span></span>0.00582000438moles</span>
that equals 0.09911770099 grams.
so 0.09911770099 grams is the answer if you round that you get about 0.1 grams
Answer:
The chemistry will need 2*10⁶ moles of antimony trifluoride.
Explanation:
The balanced reaction is:
3 CCl₄ (g) + 2 SbF₃ (s) → 3 CCl₂F₂(g) + 2 SbCl₃ (s)
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:
- CCl₄: 3 moles
- SbF₃: 2 moles
- CCl₂F₂: 3 moles
- SbCl₃: 2 moles
You can apply the following rule of three: if by reaction stoichiometry 3 moles of freon are produced by 2 moles of antimony trifluoride, 3*10⁶ moles of Freon are produced from how many moles of antimony trifluoride?
moles of antimony trifluoride= 2*10⁶
<u><em>The chemistry will need 2*10⁶ moles of antimony trifluoride.</em></u>
Answer:
1) P₄ + 5O₂ → P₄O₁₀ redox reaction
2) P₄O₁₀ + 6H₂O → 4H₃PO₄ acid-base reaction
3) Ca₅(PO₄)₃F + 5H₂SO₄ → 3H₃PO₄ + HF + 5CaSO₄ precipitation reaction
Explanation:
The reactions that take place in the <u>electric furnace method</u> are:
1) P₄ + 5O₂ → P₄O₁₀
This is a redox reaction, because the oxidation state of the reactants is changed.
2) P₄O₁₀ + 6H₂O → 4H₃PO₄
This is an acid-base reaction, because there's an exchange of H⁺ species.
The reaction that takes place in the <u>wet process</u> is:
3) Ca₅(PO₄)₃F + 5H₂SO₄ → 3H₃PO₄ + HF + 5CaSO₄
This is an precipitation reaction, because a precipitate (a solid phase in a liquid phase) is formed.
<span>CH3-N=O, [with one more O attached to N] <=====> CH2=N-O- + H+ ; this negative charge on O can be with the other O too, thus it gets stabilises itself.This is called the conjugate acid, as it has lost a proton. This is called Nitro- Acinitroso tautomerism .
I hope my answers has come to your help. God bless and have a nice day ahead!</span>
Answer:
1.5 mol
Explanation:
Step 1: Given data
- Volume of argon gas: 33 L
- Standard temperature: 273.15 K
Step 2: Calculate the moles corresponding to 33 L of argon at standard temperature and pressure (STP)
At STP, 1 mole of argon gas occupies 22.4 L.
33 L × 1 mol/22.4 L = 1.5 mol
