Answer:
Option B is correct.
Another name for equilibrium price is **market-clearing price**
Explanation:
Equilibrium price is defined as the price at which the quantity of products/goods/services demanded is equal to/matches the quantity of products/goods/services supplied.
The equilibrium price is also called the market clearing price because, at this price, there is no supply leftover (surplus) or demand leftover (deficit). The market is literally cleared!
Answer:
Do not incinerate "why the gas in the gas is initially at 23degree and 360kPa and the can has a volume of 350Ml
D
Answer:
Explanation:
From the equation:
H2SO4(aq) + 2NaOH(aq) --> Na2SO4(aq) + 2H2O (l)
<em>1 mole of the acid (H2SO4) and 2 moles of the base (NaOH) are required for complete neutralization.</em>
mole of acid (H2SO4) present = molarity x volume
= 1 x 0.1 = 0.1 mole
Mole of base (NaOH) present = mass/molar mass
= 7/40 = 0.175 mole
<em>The ratio of acid and base should be 1:2, hence the acid is slightly excessive in this case and the base is the limiting reagent that will determine the extent of the reaction.</em>
Amount of excess acid = 0.1 - 0.175/2
= 0.0125 mole
volume of excess acid = mole/molarity
= 0.0125 x 1 = 0.0125 L
= 12.5 mL
<em>Hence, the acid (H2SO4) was in excess by 12.5 mL.</em>
The volume, in liters, per kg of the Himalayan pink salt would be 0.97 L
Recall that: density = mass/volume
Hence: volume = mass/density
In this case, the density of the Himalayan pink salt is 1.03 while the mass we are working with is 1 kg.
1 kg is equivalent to 1000 g
Thus: volume = 1000/1.03
= 970.87 mL
Divide by 1000 to convert to L
970.87/1000 = 0.97 L
