Answer:
the first one is branched, the second one is also branched and the third one is cycloalkane
According to the chemical equation, the ratio between Ca and HCl for a complete reaction is 1:2. The moles of Ca can be calculated by mass/molar mass, thus 60.0 g/40 g/mole = 1.5 mole. So the moles of HCl in the solution is 1.5mole*2 = 3 mole.
So the volume of HCl solution = Moles of HCl/ concentration of HCl = 3 mole/ 1.25 M = 2.4 L = 2400 mL
Answer:
The work done is 123.5 J
Explanation:
Given that:-
Temperature = 260 K
The expression for the work done is:
Where,
n is the number of moles = 52.0 mmol =
W is the amount of work done by the gas
R is Gas constant having value = 8.314 J / K mol
T is the temperature
V₁ is the initial volume = 300 cm³
V₂ is the final volume = 100 cm³
Applying in the equation as:
The work done is 123.5 J
