</span>[HClO] is equilibrium concentration <span> of hypochlorous acid.
</span>Ka is t<span>he acid dissociation constant.</span>
Answer:
B. More reactant is added.
Explanation:
The question basically asks at which condition would the forward reaction be favoured.
The law of equilibrium states when a system at equilibrium is disturbed by, it would annul that change. In order to increase the forward reaction, more of the reactant should be added. In order to annul this change, the system would have to favour the reaction that deals with reducing the amount of reactant added.
The correct option is;
B. More reactant is added.
Answer:
N₂O₅
Explanation:
From the question given above, the following data were obtained:
Mass of compound = 7.546 g
Mass of nitrogen (N) = 1.957 g
Empirical formula =?
Next, we shall determine the mass of oxygen present in the compound. This can be obtained as follow:
Mass of compound = 7.546 g
Mass of nitrogen (N) = 1.957 g
Mass of Oxygen (O) =?
Mass of O = (Mass of compound) – (Mass of N)
Mass of O = 7.546 – 1.957
Mass of O = 5.589 g
Finally, we shall determine the empirical formula of the compound. This can be obtained as follow:
Mass of nitrogen (N) = 1.957 g
Mass of oxygen (O) = 5.589 g
Divide by their molar mass
N = 1.957 / 14 = 0.14
O = 5.589 / 16 = 0.35
Divide by the smallest
N = 0.140 / 0.14 = 1
O = 0.35 / 0.14 = 2.5
Multiply through by 2 to express in whole number
N = 1 × 2 = 2
O = 2.5 × 2 = 5
The empirical formula of the compound is N₂O₅.
Answer:
A: plants give off water vapor as a waste product as they process energy
Explanation:
Evapotranspiration in plants is defined as the process whereby water is evaporated from its leaves through transpiration during the process of photosynthesis. Different factors like wind, humidity, temperature and availability of water could make it vary.
Comparing all the options, to this definition, the correct answer is Option A.
