Answer:
Molar mass= 78.8gmol-1
Explanation:
P= 550torr, V= 0.0732dm3, m= 0.5g , R= 8.314, T= 273+489= 762K
Applying
PV= m/Mm×(R×T)
Substitute and Simplify
Mm= 78.8gmol-1
Explanation:
solar and energy i had to answer this one before
Answer:

Explanation:
Given that:
Half life =
days
Where, k is rate constant
So,
The rate constant, k = 0.00007 days⁻¹
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given:
5 % is lost which means that 0.05 of
is decomposed. So,
= 1 - 0.05 = 0.95
t = ?
t = 732.76 days = 
Answer:
Reactants are favored over products in the reaction
