A 1.24g sample of a hydrocarbon, when completely burned in an excess of O2 yields 4.04g Co2 and 1.24g H20. Draw plausible struct
arsen [322]

Answer:

Plausible structure has been given below

Explanation:

  • Molar mass of CO_{2} is 44 g/mol and molar mass of H_{2}O is 18 g/mol
  • Number of mole = (mass/molar mass)

4.04 g of CO_{2} = \frac{4.04}{44}moles CO_{2} = 0.0918 moles of CO_{2}

1 mol of CO_{2} contains 1 mol of C atom

So, 0.0918 moles of CO_{2} contains 0.0918 moles of C atom

1.24 g of H_{2}O = \frac{1.24}{18}moles H_{2}O = 0.0689 moles of H_{2}O

1 mol of H_{2}O  contain 2 moles of H atom

So, 0.0689 moles of H_{2}O contain (2\times 0.0689)moles of H_{2}O or 0.138 moles of H_{2}O

Moles of C : moles of H = 0.0918 : 0.138 = 2 : 3

Empirical formula of hydrocarbon is C_{2}H_{3}

So, molecular formula of one of it's analog is C_{4}H_{6}

Plausible structure of C_{4}H_{6} has been given below.

Nookie1986 [14]

Answer:

See explanation

Explanation:

The major difference between distance and displacement is that distance is a scalar quantity while displacement is a vector quantity. Scalar quantities have magnitude without direction while vector quantities have both magnitude and direction.

The distance covered by Benjamina in both cases just refer to the difference in her position at each time without reference to the direction in which she changed her position.

Her displacement will clearly mention the direction in which she moved both when she walked to the front door of her apartment and when she walked to a friend's apartment.

pav-90 [236]

Answer:

To know this

get the pH

pH= -log(H+)

pH= -log(1x10^-5)

pH= 5.

It is Acidic.

Acidic ranges from 1 - 7

It falls within this range
