Answer:

267.57 kPa

Explanation:

Ideal gas law:

PV = n RT        R = 8.314462    L-kPa/K-mol

P (16.5) = 1.5 (8.314462)(354)       P = 267.57 kPa

S8 + 12 O2 → 8 SO3<br>How many moles of SO3 can be produced from 6 moles of O2?
MA_775_DIABLO [31]

Answer:

4 moles of SO3 will be produced from 6 moles of oxygen.

Explanation:

From the reaction given

S8 + 12 O2 ----> 8 SO3

12 moles of oxygen reacts to form 8 moles of SO3

if 6 moles of oxygen were to be used instead, it has been reduced to half of the original mole of oxygen used. Then the moles of SO3 will also be reduced to half.

6 moles of O2 will yield 4 moles of SO3

12 moles = 8 moles

6 moles = ?

? = 6 * 8 / 12

? = 48/ 12

? = 4 moles of SO3.

A balloon inflated in a room that is 34 C has a volume of 5.00 liters. The room is then heated to a temperature of 68 C. What is
Eduardwww [97]

Answer:-

5.554 litres

Explanation:-

Initial Volume V 1 = 5.00 litres

Initial temperature T 1 = 34 C + 273 = 307 K

Final temperature T 2 = 68 C + 273 = 341 K

Using the relation of Charles Law (V 1 / T 1) = (V 2 / T 2)

New Volume V 2 = V1 x T2 / T1

Plugging in the values

V2 = 5.00 litres x 341 K / 307 K

= 5.554 litres.
