Explanation:
The chemical reaction equation will be as follows.
As 1 mole reacts with 1 mole of
Hence, moles of = Molarity × Volume (in mL)
= 0.5 × 38.0 mL
= 0.019 mol
Moles of = Molarity × Volume (in mL)
= 0.6 × 42.0 mL
= 0.0252 mol
As moles of CuS is less than the moles of . This means that CuS is the limiting reagent.
Thus, maximum moles of CuS formed are 0.019 mol. As molar mass of CuS is 95.6 g/mol.
Therefore, maximum mass of CuS can be formed is
= 1.8164 g
Thus, we can conclude that maximum mass of CuS formed is 1.8164 g.
Answer: Option (b) is the correct answer.
Explanation:
According to ideal gas law, the product of pressure and volume is equal to the product of number of moles, gas constant and temperature.
Mathematically, PV = nRT
So, when there are two gases with equal number of moles behaving ideally then the ideal gas equation will be as follows.
=
and =
Hence, when temperature and pressure of both the gases will be constant then = 1.
Thus, we can conclude that constant temperature and pressure is the conditions that must be met for a volume ratio to be created from a balanced chemical equation.
Answer:
1.346 meters per second
Explanation:
You traveled 35 meters in 26 seconds
