I believe 11.

Since the first 5 is in the outside, it’s 5 times the number.

In H2O there are already 2 hydrogen and 1 oxygen molecule, totaling to 3.

When you put 5 H2’s, and add them, that would equal 10 molecules, plus the O on the end, would equal 11.

at constant atmospheric pressure, the temperature of a gas that occupies the volume of 5.30 L is 298 K. what is the temperature
harkovskaia [24]

Answer:

The new temperature of the gas is 427K

Explanation:

In this case we use Charles's Law according to which the volume and temperature of a certain amount of gas are related, keeping the pressure constant.

V1 / T1 = V2 / T2

5,30L/298K=7,60L/T2

T2=7,60L/(5,30L/298K)=427,32K

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
