For the following reaction, 9.60 grams of butane (C4H10) are allowed to react with 17.0 grams of oxygen gas. butane (C4H10) (g)
dangina [55]

Answer:

14.4 g of CO_{2} can be produced.

Explanation:

Balanced equation: 2C_{4}H_{10}+13O_{2}\rightarrow 8CO_{2}+10H_{2}O

                                        Molar mass (g/mol)

                  C_{4}H_{10}                    58.12

                    O_{2}                         32

                  CO_{2}                       44.01

So, 9.60 g of C_{4}H_{10} = \frac{9.60}{58.12}mol=0.165mol

      17.0 g of O_{2} = \frac{17.0}{32}mol=0.531mol

According to balanced equation-

2 moles of C_{4}H_{10} produce 8 moles of CO_{2}

So, 0.165 moles of C_{4}H_{10} produce (\frac{8}{2}\times 0.165)mol of CO_{2}  or 0.660 moles of CO_{2}

13 moles of O_{2} produce 8 moles of CO_{2}

So, 0.531 moles of O_{2} produce (\frac{8}{13}\times 0.531)moles of CO_{2} or 0.327 moles of CO_{2}

As least number of moles of CO_{2} are produced from O_{2} therefore O_{2} is the limiting reagent.

So, maximum amount of CO_{2} that can be formed = 0.327 moles

                                                                              = (0.327\times 44.01)g

                                                                              = 14.4 g

A ballon is inflated with 2.42L of helium at a temperature of 27.0°C. When put in the freezer, the volume changes to 2.37L and -
natita [175]

Answer:

838 torr  

Step-by-step explanation:

To solve this problem, we can use the <em>Combined Gas Laws</em>:

p₁V₁/T₁ = p₂V₂/T₂            Multiply each side by T₁

   p₁V₁ = p₂V₂ × T₁/T₂     Divide each side by V₁

      p₁ = p₂ × V₂/V₁ × T₁/T₂

<em>Data: </em>

p₁ = ?;             V₁ = 2.42 L; T₁ =  27.0 °C

p₂ = 754 torr; V₂ = 2.37 L; T₂ =  -8.8 °C

Calculations:

(a) Convert <em>temperatures to kelvins </em>

T₁ = (27.0 + 273.15) K = 300.15 K

T₂ = (-8.8 + 273.15) K = 264.35 K

(b) Calculate the<em> pressure </em>

p₁ = 754 torr × (2.37 L/2.42) × (300.15/264.35)  

p₁ = 754 torr × 0.979 × 1.135

p₁ = 838 torr

MAXImum [283]

Answer:0.20L

Explanation:

Data

P1 =0.524atm

V1=2L

P2=5.15atm

V2=?

Apply Boyle' law

P1V1 =P2V2

P2 =P1V1/P2

= 0.524x 2 /5.15

= 0.20 L
