The correct answer is the first option. Natural gas is a naturally occurring gas mixture which is composed mainly of methane or CH4. Sometimes, it contains traces of carbon dioxide, nitrogen helium or hydrogen sulfide. They are produced due to decomposing plant and animals exposed to pressure and heat energy.
Answer:
4.15×10⁻²¹ moles of Sn
Explanation:
This question can be solved by a simple rule of three.
We know that 1 mol contains 6.02×10²³ particles.
In this case, our particles are the atoms, so:
6.02×10²³ atoms / 1 mol . 2500 atoms = 4.15×10⁻²¹ moles.
The knowledge of mol can be applied for everything:
A mol of molecules
A mol of atoms
A mol of a compound
Answer:
Asteroids???? idk and its not a guaranteed answer
Answer: It will take 0.50 minutes for it to decompose to 28.2% of its initial value
Explanation:
Integrated rate law for second order kinetics is given by:
a= concentration left after time t = 
k = rate constant =
= initial concentration = 1.77
t= time taken for decomposition
Thus it will take 0.50 minutes for it to decompose to 28.2% of its initial value
Answer:
the volume of the gas at 2.50 atm pressure is equal to 1.44 Litres.
