Mixed Practice:
Afina-wow [57]

Given

Mass of NO - 824 g

Molar mass of NO - 30.01g/mol

No of moles of NO = Given mass/Molar mass

No of moles of NO = 824/30.01= 27.45 mole

Hence 27.5 moles of NO are formed!

What is the importance of validity
finlep [7]

Answer:

validity is the extent to which a test measures what it claims to measure. It is vital for a test to be valid in order for the results to be accurately applied and interpreted.

Explanation:

Validity is important because it can help determine what types of tests to use, and help to make sure researchers are using methods that are not only ethical, and cost-effective, but also a method that truly measures the idea or constructs in question.

If nicotine has a molar mass of 160±5g/mol , what is its molecular formula?
navik [9.2K]

Answer:

C10H14N2

Explanation:  

I don't believe one can deduce the molecular formula from just it's molar mass.  There are too many possible combinations of elements that could add to the same mass.  This is the correct formula for nicotine, taken from known information, not from an analysis of the molar mass alone.  One can confirm the molar mass is in the correct range:

C10:  10*12 = 120

H14:   14*1 =    14

N2:     2*14 =  <u> 28</u>

Total =             162  which is 160±5g/mol

What is the force of attraction between the particles in a salt crystal
Papessa [141]

Answer:

Electrostatic attraction between the ions

Step-by-step explanation:

A salt crystal consists of Na⁺ and Cl⁻ ions stacked together in a crystal.

The ions have opposite charges, so they are electrostatically attracted to each other.

Because the ions are so close together, the attractive forces are quite large.
