The time taken for the concentration of N2O to decrease to 32% of its initial concentration is calculated as follows
In(A1/A0)=-Kt
A1= final concentration = 32/100=0.32
A0= initial concentration =100/1000=1
K= constant= 0.76 per sec
time is therefore calculated as follows
In(0.32/1)= -0.76 t
-1.1394 =-0.76t divide both sid3es by -0.76
t is therefore= 1.5 s
Multiply by 1.8 and then add 32.
Answer:
Wall, cup, mug, plastic spoon
Explanation:
Because all of those are glass and it is important to us to make sure that if you are touching this brle careful
Most atoms do not. For those atoms that do not have a full valence shell (which usually would contain eight electrons, except for hydrogen and helium, where it would contain two), something has to change. So nature's tendency toward a full valence shell will lead to one of two things: The gain or loss of electrons.
A catalyst is a compound that accelerates a chemical reaction without getting used up in the process.
Un catalizador es un compuesto que acelera una reacción química sin ser agotado en el proceso.
