The volume which is occupied by 0.445 mol of carbon dioxide at 397K and 973mmHg is 11.32 L.
<h3>What is ideal gas equation?</h3>
Ideal gas equation will be represented as:
PV = nRT, where
P = pressure = 973 mmHg = 1.28 atm
V = volume = ?
n = moles = 0.445 mol
R = universal gas constant = 0.082 L.atm / K.mol
T = temperature = 397 K
On putting all these values, we get moles as:
V = (0.445)(0.082)(397) / (1.28) = 11.317 = 11.32 L
Hence required volume of gas is 11.32 L.

Answer:
652.6 g of H₃PO₄ are formed
Explanation:
Reaction is:
P₄O₁₀(s) + 6H₂O(l) → 4H₃PO₄(aq)
As P₄O₁₀ is the reactant in excess, the limiting is water.
Ratio is 6:4. We make a rule of three:
6 moles of water produce 4 moles of phosphoric acid
Therefore, 10 moles of water may prodyce (10 .4) / 6 = 6.66 moles of H₃PO₄
We convert the moles to mass:
6.66 moles . 97.9 g / 1mol = 652.6 g
Hi Jojo
The 4 factors that makes a good fuel are
1) It should be cheap
2)It should not burn too fast or too slowly
3) It should be easily available
4) It should have a high calorific value
I hope that's help !
Answer:
When the ambulance is coming towardss you the waves are smushed together and sound higher pitched but then it passes you and when tracveling away the waves are scretched out so the whee whoo sounds lower and that is because of the doppler effect
Answer:
See explanation, some might be graded as wrong if it's an automatic grading system but most
Explanation:
1. lose
2. valence
3. noble (Atoms don't actually always do this, but since the word gas is after the blank, it is the only option)
4. 4
5. have
6. 10
5 and 6 are a little ambiguous and could have many answers
