Answer:
HBr + H2O = H3O+ + Br-
So our conjugate acid is the H3O+ to H2O
Explanation:
A conjugate acid of a base results when the base accepts a proton.
Consider ammonia reacting with water to form an equilibrium with ammonium ions and hydroxide ions:
NH3 (aq) + H2O (l) ⇌ NH4+ (aq) + OH- (aq)
Ammonium, NH4+, acts as a conjugate acid to ammonia, NH3.
Answer:
Option (A)
Explanation:
The temperate forest usually covers the tropical and the taiga region. The trees in this forest region experience all the four seasons namely summer, autumn, winter and spring. It comprises approximately 25% of the total forest-covered region on earth. The leaves of these trees change color during the autumn season, which eventually falls off during the winter season, and again, new leaves grow back during the spring season. This enables the plants to survive and go through the cold temperature in the winter.
Thus, the correct answer is option (A).
Yes; you need to know how long the light bulb is on.
<h3>How much electricity does a light bulb use?</h3>
Because of this, lower wattage bulbs are sometimes referred to as "equivalent to 60W"; nevertheless, what is equal is brightness, not energy consumption.
Converting wattage to kilowatts is the best way to determine how much energy your lightbulb consumes. Thus, 0.1 kW would be needed per hour for a 100W light bulb.
Incandescent (up to 100W) and halogen (up to 120W) light bulbs with higher energy consumption are being phased out. You may get ornamental exposed carbon filament light bulbs, which are normally 40–60W, if you still have any of them operating in your house.

The minimum volume of water needed is 0.28 mL. The solution will have
1.7 mg of phthalic acid remaining in solution.
<em>At 100 °C</em>
Volume of water required = 50 mg HPh × (100 mL water/18 000 mg HPh)
= 0.28 mL water
<em>At 25 °C
</em>
Mass of HPh in solution = 0.28 mL water × (620 mg HPh/100 mg water)
= 1.7 mg HPh
