As the temperature of a gas increases, explain what happens to its density and why.
Ghella [55]

Answer:

When a gas is heated, the molecules move faster, bump into each other, and spread apart. Because the molecules are spread apart, they take up more space. They are less dense.

If a sample contains 21.2g N how many moles of N does it contain
tigry1 [53]

Hey there!

The molar mass of nitrogen is 14.007.

Convert grams to moles:

21.2 ÷ 14.007 = 1.51

The sample containing 21.2g of nitrogen contains 1.51 moles of nitrogen.

Hope this helps!

An unknown triprotic acid (H3A) is titrated with NaOH. After the titration Ka1 is determined to be 0.0013 and Ka2 is determined
e-lub [12.9K]

Answer:

6.68 X 10^-11

Explanation:

From the second Ka, you can calculate pKa = -log (Ka2) = 6.187

The pH at the second equivalence point (8.181) will be the average of pKa2  and pKa3. So,

8.181 = (6.187 + pKa3) / 2

Solving gives pKa3 = 10.175, and Ka3 = 10^-pKa3 = 6.68 X 10^-11
