Answer:

2900 moles gas

Explanation:

PV =nRT => n = PV/RT

at STP ...

P = 1 Atm

V = 64.6KLiters = 6.46 x 10⁴ Liters

n = unknown

R = 0.08206 L·Atm/mol·K

T = 0⁰C = 273K

n = (1 Atm)(6.46 x 10⁴L)/(0.08206 L·Atm/mol·K)(273K) = 2897 moles ≈ 2900 moles

The functional groups in an organic compound can frequently be deduced from its infrared absorption spectrum. A compound contain
Klio2033 [76]

The peaks at 3300 cm-1 and 2200 cm-1 are due to terminal alkyne group (triple bond between two carbons) and triple bonded C-H stretching

So

The answer is : terminal alkyne

Another peak near 3430 cm-1 must be due to an -OH group

so the answer is : alcohol

Some water released 7800 J of energy when cooled from 78°C to 33°C. What was the mass of the water?
Karo-lina-s [1.5K]

Answer:

-41. 47

Explanation:

m = q / Cp x T

m = Mass

q = Energy (or joules)

Cp = Heat Capacity

T = Change in Temperature

Water's heat capacity is always 4.18.

This is the formula you'll need for change in temperature:

Final - Initial

So, 33 - 78 = -45

m = 7800 / 4.18 x -45

= -41.47
