Answer:

d. the conjugate base of the weak acid

Explanation:

The strong base (BOH) is completely dissociated in water:

BOH → B⁺ + OH⁻

The resulting conjugate acid (OH⁻) is a weak acid, so it remains in solution as OH⁻ ions.

By other hand, the weak acid (HA) is only slightly dissociated in water:

HA ⇄ H⁺ + A⁻

The resulting conjugate base (A⁻) is a weak base. Thus, it reacts with H⁺ ions from water to form HA, increasing the concentration of OH⁻ ions in the solution.

Therefore, the resulting solution will have a pH > 7 (basic).

<u>Answer:</u> The gas produced when sodium phosphide reacts with water is phosphine.

<u>Explanation:</u>

When sodium phosphide reacts with water molecule, it leads to the production of flammable, poisonous gas known as phosphine along with the production of sodium hydroxide.

The chemical reaction for the reaction of sodium phosphide with water follows the equation:

Na_3P(aq.)+3H_2O(l)\rightarrow PH_3(g)+3NaOH(aq.)

By Stoichiometry of the reaction:

1 mole of sodium phosphide reacts with 3 moles of water to produce 1 mole of phosphine gas and 3 moles of sodium hydroxide.

Hence, the gas produced when sodium phosphide reacts with water is phosphine.

6.0 L of oxygen gas is at a temperature of 5K. If the temperature of the gas is lowered to 1K at constant pressure, what is the
DerKrebs [107]

Answer:

THE NEW VOLUME AT 1 K IS 1.2 L

Explanation:

Using Charles' law which states that the volume of a given gas is directly proportional to its temperature provided the pressure remains constant.

Mathematically written as;

V1/T1 = V2/T2   at constant pressure

V1 = Initial volume = 6L

T1 = initial temperature = 5K

T2 = Final temperature = 1K

V2 = final volume = unknown

Re-arranging the equation by making V2 the subject of the equation, we obtain;

V2 = V1 T2 / T1

V2 = 6 * 1 / 5

V2 = 1.2 L

The new volume of the gas sample at 1 K is 1,2 L

How does conduction happen?
pashok25 [27]

Answer:

Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. ... The fire's heat causes molecules in the pan to vibrate faster, making it hotter. These vibrating molecules collide with their neighboring molecules, making them also vibrate faster.
