A sample of a compound that contains only the elements c, h, and n is completely burned in o2 to produce 44. 0 g of co2, 45. 0 g

Elan Coil [88]

Answer:

B. CH₅N

Explanation:

The combustion reaction of a compound CₐHₓNₙ with O₂ is:

CₐHₓNₙ + O₂ → a CO₂ + X/2 H₂O + n NO₂

Where 1 mole of CₐHₓNₙ with an excess of O₂ produce a moles of CO₂, X/2 moles of H₂O and n moles of NO₂

Thus, you need to convert the mass of CO₂ and H₂O to moles to find the C:H ratio and determine a possible empirical formula thus:

Moles CO₂ (Molar mass 44g/mol):

44g ₓ (1mol / 44g) = 1 mole CO₂ = 1 mole C

Mole of H₂O (Molar mass 18g/mol):

45g ₓ (1 mol / 18g) = 2.5 moles H₂O = 5 moles H

Thus, in the compound you have 5 moles of H per mole of C, and a possible empirical formula is:

B. CH₅N

The only structure that meet this C:H ratio

A girl runs 40 m, west, 50 m south, 60 m, east. what is his net displacement?

balandron [24]

The displacement of the girl which the relative change in her position from her starting point. Therefore, the shortest distance between her initial and final position is 58.85 m North - West

From the sketch of the girls movement attached below, the displacement of the girl can be calculated thus :

Using Pythagoras :

Displacement, d = √(50² + 20²)

d = √(2500 + 400)

d = √2900

d = 53.851

Therefore, the displacement of the girl, which is the shortest distance between her current position and starting position is 53.85 meters NW.
