igomit [66]

Answer:

391.46 L

Explanation:

Given:

Initial temperature of the water = 23.4°C

Final temperature of the water = 39°C

Temperature change for the water, ΔT = (39 - 23.4) = 15.6°C

Heat absorbed by the water = 2.55 × 10⁴ kJ = 2.55 × 10⁷ J

Density of the water = 0.998 g/mL

Specific heat of the water, C = 4.184 J/g°C

Now,

The heat absorbed by the water, q = mCΔT

where, m is the mass of the water

Thus,

we have

2.55 × 10⁷ J = m × 4.184 × 15.6

m = 390682.45 grams

also,

Density = mass / volume

thus,

0.998 = 390682.45 / volume

Volume = 391465.38 mL

Volume = 391.46 L

A compound with molecular formula C4H8O2, shows absorptions at 2500-3300 cm-1 (broad), 1720 cm-1 and at 1200 cm-1 on the IR spec

xxMikexx [17]

Answer:

Butanoic Acid:

I have attached the structure of Butanoic Acid. Please refer to the attachment.

Explanation:

Solution:

First of all, we need to calculate the double bond equivalent (DBE) for the compound given:

Compound = C4H8O2

DBE = (C +1) - (H + X - N)/2

C = no. of carbons

H = no. of Hydrogen

X = no. of Halogens

N = no. of Nitrogen

DBE = (4+1) - (8/2)

DBE = 5-4

DBE = 1

It indicates the presence of 1 double bond in the possible structure.

Further structure can be identified by looking the peak values of the spectrum. So, we have,

2500 - 3300 = it indicates the presence of -COOH group

1720 = it indicates the (C=0) stretching

1200 = It indicates the (C-O) stretching

SO, the possible structure is

Butanoic Acid:

I have attached the structure of Butanoic Acid. Please refer to the attachment.

which of the following activities could cause liquid molecules to overcome intermolecular attractive forces and become gas molec

Anna [14]

The answer is C. increasing the temperature of the liquid.

Increasing the temperature of the liquid also means that you are providing energy to the liquid, which makes the molecules overcome intermolecular attractive forces, move more constantly, and become gas molecules.

Hope this would help~
