<u>Answer:</u> The momentum of the ball is 1.87 g m/s.

<u>Explanation:</u>

Momentum of an object is defined as the product of mass of the object and the velocity of the object. Mathematically,

p=mv

where,

p = momentum of the ball = ? g m/s

m = mass of the ball = 2.20 grams

v = velocity of the ball = 0.850 m/s

Putting values in above equation, we get:

p=2.20g\times 0.850m/s=1.87gm/s

Hence, the momentum of the ball is 1.87 g m/s.

An unknown triprotic acid (H3A) is titrated with NaOH. After the titration Ka1 is determined to be 0.0053 and Ka2 is determined
Savatey [412]

Answer:

Ka3 for the triprotic acid is 7.69*10^-11

Explanation:

Step 1: Data given

Ka1 = 0.0053

Ka2 = 1.5 * 10^-7

pH at the second equivalence point = 8.469

Step 2: Calculate Ka3

pKa = -log (Ka2) = 6.824

The pH at the second equivalence point (8.469) will be the average of pKa2  and pKa3. So,

8.469 = (6.824 + pKa3) / 2

pKa3 = 10.114

Ka3 = 10^-10.114 = 7.69*10^-11

Ka3 for the triprotic acid is 7.69*10^-11

According to Arrhenius, NH4+ an acid or a base? Write an equation to support
sergejj [24]

According to Arrhenius definition of acids, NH4^+ is an acid.

According  to Arrhenius  definition of acids and bases, acid is any substance that produces hydrogen ion in solution as its only positive ion.

Following this definition, let us now consider what happens when NH4^+ is introduced into a water;

NH4^+(aq)-------> NH3(aq) + H^+(aq)

Hence, according to Arrhenius definition of acids, NH4^+ is an acid.

For another example of Arrhenius acids, see
