The dissolution of ammonium nitrate, NH4NO3, in water is an endothermic process. Since the calorimeter is not a perfect insulato

r, will the enthalpy of solution for ammonium nitrate be reported as too high or too low if this heat change is ignored? Explain

Answer:  

Explanation:  As already mentioned that the dissolution of ammonium nitrate in water is an endothermic process, which explains that more energy would be needed to break the bond between the reactants rather than the formation of the products.  

Hence, the enthalpy of the solution for ammonium nitrate would be positive in nature as energy is being given to the reactants molecules to get converted into the products.

Describe a method to calculate the average atomic mass of using only the atomic masses of
AnnZ [28]

Answer:

Average amu is 6.52556

Explanation:

Average the numbers

Add the two masses together.

6.01512+ 7.01600= 13.03112

Then divide by 2, we divide by 2 because that is how many #'s we are given.

13.03112/ 2= 6.52556

A neutral atom has the atomic number of 10 and the atomic mass is 22 amu. what is the number of neutrons and electrons for this
Leviafan [203]

Hey there!

This atom has 10 protons.

If this atom has an atomic mass of 22, that means the sum of protons and neutrons is 22.

p + n = 22

p = 10

Which makes this true:

10 + n = 22

Subtract 10 from each side to solve for n, the number of neutrons.

n = 12

An atom that has the atomic number of 10 and an atomic mass of 22 has 12 neutrons.

Hope this helps!

Question 231.15 pts A 0.200 M solution of a weak monoprotic acid HA is found to have a pH of 3.00 at room temperature. What is t
MariettaO [177]

Answer:

The correct answer is: Ka= 5.0 x 10⁻⁶

Explanation:

The ionization of a weak monoprotic acid HA is given by the following equilibrium: HA ⇄ H⁺ + A⁻. At the beginning (t= 0) we have 0.200 M of HA. Then, a certain amount (x) is dissociated into H⁺ and A⁻, as is detailed in the following table:

               HA               ⇄        H⁺        +          A⁻

t= 0      0.200 M                     0                     0

t              -x                             x                       x

t= eq      0.200M -x               x                       x

At equilibrium, we have the following ionization constant expression (Ka):

Ka= \frac{ [H^{+}]  [A^{-} ]}{ [HA]}

Ka= \frac{x x}{0.200 M -x}

Ka= \frac{x^{2} }{0.200 M - x}

From the definition of pH, we know that:

pH= - log  [H⁺]

In this case, [H⁺]= x, so:

pH= -log x

3.0= -log x

⇒x = 10⁻³

We introduce the value of x (10⁻³) in the previous expression and then we can calculate the ionization constant Ka as follows:

Ka= \frac{(10^{-3})^{2}  }{0.200 - (10^{-3}) }= \frac{10^{-6} }{0.199}= 5.025 x 10⁻⁶= 5.0 x 10⁻⁶
