Answer: i think the best bet i can give you is Option C (2:3)
Explanation: i apologize i haven't done chem in 2 years
but however to put it in retrospect the finished equation is 2(AL)^+3 3(O)^-2
Answer:
The final temperature at 1050 mmHg is 134.57 or 407.57 Kelvin.
Explanation:
Initial temperature = T = 55 = 328 K
Initial pressure = P = 845 mmHg
Assuming final to be temperature to be T' Kelvin
Final Pressure = P' = 1050 mmHg
The final temperature is obtained by following relation at constant volume
The final temperature is 407.57 K
A.)49.4974874 moles or 49.5 moles
B.)2.980808730172671e+25 or 3e+25
Answer: for the reaction is -186.75 J/K
Explanation:
Change in entropy () for the given reaction under standard condition is given by-
=
So = = -186.75 J/K
Answer:
Kj/mol
Its an endothermic reaction
Explanation:
Enthalpy can be evaluated by using following formula -
where
q is the enthalpy or change in internal energy
m is the mass in kg
c is the specific heat
and is the change in temperature
Mass of HCl is equal to g/mol
or
Mass of HCl is equal to Kg/mol
Substituting the given values in above equation, we get-
Kj/mol
Enthalpy is positive thus it is an endothermic reaction
