Answer:
≈ 0.10M
Explanation:
[A]o = 0.27M
Rate constant, k = 0.75 s−1
[A] = ?
time, t = 1.3
Integrated formular for a first order reaction is given as;
ln[A] = ln[A]o − kt
ln[A] = ln(0.27) - 0.75(1.3)
ln[A] = -1.309 - 0.975
ln[A] = -2.284
[A] = 0.1019M ≈ 0.10M
Answer:
No. of molecules= mass/molar mass ×avogadro no.
= 13.2/50×6.02×10°23
No. of molecules =1.59×10°23

Answer:
133.340538.
Explanation:
The answer is 133.340538. We assume you are converting between grams AlCl3 and mole. You can view more details on each measurement unit: molecular weight of AlCl3 or mol This compound is also known as Aluminium Chloride. The SI base unit for amount of substance is the mole.
Unlike other reactions, combustion requires oxygen in order to occur.
This means that oxygen is a necessary condition for any combustion reaction to occur.
Based on the above, the difference between combustion reaction and other reactions is:
- It requires oxygen as an input or a medium to occur in
Hope this helps :)
