Answer:

The correct option is OH⁻ from the strong base to form water and a salt

Explanation:

The reaction between an acid and a base is called a neutralization reaction. A neutralization reaction is the reaction between an acid (weak or strong) and a base (weak or strong) to produce salt and water. Here, the hydrogen ion (H⁺) ionized from the acid combines with the hydroxyl ion (OH⁻) ionized from the base to produce water. While the metallic cation from the base combines with the nonmetallic anion from the acid to form salt.

The illustration provided in the question is no different, although a weak acid ionizes partially in water i.e not all the hydrogen atoms are ionized to form hydrogen ions.

Examples of such reactions between a weak acid

(CH₃COOH) and a strong base (NaOH) is

CH₃COOH + NaOH  ⇒ CH₃COONa + H₂O

kkurt [141]

Explanation:

The given data is as follows.

             P = 3 atm

                = 3 atm \times \frac{1.01325 \times 10^{5} Pa}{1 atm}  

                 = 3.03975 \times 10^{5} Pa

    V_{1} = 9 L = 9 \times 10^{-3} m^{3}    (as 1 L = 0.001 m^{3}),  

        V_{2} = 15 L = 15 \times 10^{-3} m^{3}

            Heat energy = 800 J

As relation between work, pressure and change in volume is as follows.

                  W = P \times \Delta V

or,                W = P \times (V_{2} - V_{1})

Therefore, putting the given values into the above formula as follows.

                  W = P \times (V_{2} - V_{1})

                      = 3.03975 \times 10^{5} Pa \times (15 \times 10^{-3} m^{3} - 9 \times 10^{-3} m^{3})

                      = 1823.85 Nm

or,                   = 1823.85 J

As internal energy of the gas \Delta E is as follows.

                     \Delta E = Q - W

                                  = 800 J - 1823.85 J

                                  = -1023.85 J

Thus, we can conclude that the internal energy change of the given gas is -1023.85 J.

What would happen if the number of protons were to change in an atom?
Shalnov [3]

Answer: you will change the atom from one element to a different element. Sometimes, when you add a proton to an element, the element will become radioactive. If you change the number of neutrons in an atom, you get an isotope of the same element.
