The addition of NaOH to water would result in which of the following?
EleoNora [17]

Answer:

A decrease in [H3O+] and an increase in pH (option a)

Explanation:

Equilibrium of water is shown in this equation

2H₂O  ⇄  H₃O⁺  +  OH⁻

When you add NaOH, you are modifying [OH⁻]

NaOH  →   Na⁺  +  OH⁻

In equilibrium of water, the [OH⁻] increases

2H₂O   ⇄   ↓  H₃O⁺   +   OH⁻  ↑

As the [OH⁻] increases, by Le Chatellier, the equilibrium tends to decrease [H₃O⁺].

If the [OH⁻] is higher, pH  is also high so the solution of water and sodium hydroxide would be totally basic.

The Charles Zeppelin, a fictional airship, is filled with 2.16 x 105 liters of hydrogen gas (H2). On the ground, the airship’s t
Dmitry [639]

Answer:

V2 = 3.11 x 105 liters

Explanation:

Initial Volume, V1 = 2.16 x 105 liters

Initial Temperature, T1 = 295 K

Final Temperature, T2 = 425 K

Final Volume, V2 = ?

These quantities are related by charle's law and the equation of the law is given as;

V1 / T1  =  V2 / T2

V2 = T2 * V1 / T1

V2 = 425 * 2.16 x 105 / 295

V2 = 3.11 x 105 liters
