Identify the gas law that applies to the following scenario: If a gas in a closed container is pressurized from 18.0 atm to 14.0

atm and its original
temperature was 35.0°C, what would the final temperature of the gas be?

O Avogadro's Law
O Boyle's Law
O Gay-Lussac's Law

Answer:

Gay-Lussac's Law

Explanation:

The pressure is directly proportional to the absolute temperature under constant volume. This states the Gay-Lussac's law. The equation is:

P1T2 = P2T1

<em>Where P is pressure and T absolute temperature of 1, initial state and 2, final state of the gas.</em>

<em />

That means the right option is:

- Gay-Lussac's Law

The general rule of thumb is that the (smaller or larger) a substance's atoms and the (stronger or weaker) the bonds, the harder
Luda [366]
Answer is: <span>The general rule of thumb is that the smaller a substance's atoms and the stronger the bonds, the harder the substance will be. 
If the distance between atoms is higher, lesser will be attraction between electrons and protons of atoms, smaller distance means stronger atoms attraction.

How many grams of Fe2O3 are formed when 16.7 moles of Fe reacts completely with
lesantik [10]

Answer:

The answer to your question is 1) 1336 g of Fe₂O₃  2) 1 mol of H₃PO₄

Explanation:

1)

Data

mass of Fe₂O₃ = ?

moles of Fe = 16.7

Balanced chemical reaction

                 4Fe  +  3O₂  ⇒   2Fe₂O₃

a.- Calculate the moles of Fe₂O₃

                 4 moles of Fe ----------------- 2 moles of Fe₂O₃

                16.7 moles of Fe --------------  x

                                    x = (16.7 x 2)/4

                                    x = 33.4/4

                                    x = 8.35 moles of Fe₂O₃

b.- Calculate the molar mass of Fe₂O₃

Fe₂O₃ = (2 x 56)+ (3 x 16) = 112 + 48 = 160 g

c.- Convert moles to mass

                       160 g of Fe₂O₃ ------------ 1 mol

                          x                     ------------ 8.35 moles of Fe₂O₃

                          x = (8.35 x 160)/1

                          x = 1336 g of Fe₂O₃

2)

moles of H₃PO₄ = ?

mass of P₄O₁₀ = 71 g

Balanced chemical reaction

         P₄O₁₀ + 6H₂O ⇒ 4H₃PO₄

a.- Calculate the molar mass of P₄O₁₀

P₄O₁₀ = (31 x 4) + (16 x 10) = 124 + 160 = 284 g

b.- Convert the mass of P₄O₁₀ to moles

                   284 g ------------------- 1 mol

                     71 g -------------------- x

                       x = (71 x 1)/284

                       x = 0.25 moles of P₄O₁₀

c.- Calculate the moles of H₃PO₄

                   1 mol of P₄O₁₀ ---------------- 4 moles of H₃PO₄

                  0.25 moles     -----------------  x

                      x = (0.25 x 4) / 1

                     x = 1 mol of H₃PO₄
