Use the van der Waals equation and the ideal gas equation to calculate the pressure for 1.50 mol He gas in a 1.00 L container at
Tamiku [17]

The difference in pressure is <u>8.98 %.</u>

What is pressure ?

In the physical sciences, pressure is defined as the stress at a point within a confined fluid or the perpendicular force per unit area. A 42-pound box with a bottom area of 84 square inches will impose pressure on a surface equal to the force divided by the area it is applied to, or half a pound per square inch. Atmospheric pressure, which is roughly 15 pounds per square inch at sea level, is the weight of the atmosphere pressing down on each unit area of the Earth's surface. Pascals are used to express pressure in SI units; one pascal is equivalent to one newton per square meter. Almost 100,000 pascals of atmospheric pressure are present.

A compound with molecular formula C6H9No that has an amide functional group and does not have an alkene group
Flauer [41]

Answer:

Following are the responses to the given question:

Explanation:

\to C_6H_9NO

calculating the HOI:

= \frac{2C+2+N-H-X}{2} \\\\ =\frac{2\times 6+2+1-9-0}{2}\\\\ =\frac{12-6}{2}\\\\=\frac{6}{2}\\\\=3

So, in the above compund there are three bounds or we can say that one is double and two bound is single.

Please find the attachment file of the Function group:

In the above given conditon compound doesn't include the alkene functional group that is absense of-C=C- , and compound include -C\equiv C-  So, please find the attached file of the structure of the compound:

It should be scientific law since a hypothesis is like a prediction and a theory could be used to explain something although it might not be true. There’s many theories just to explain one thing. So it should be scientific law
