Answer:
if the oil is already 60 c and you heat up the hot plate to the same degree you are not changing anything
hope this helps :)
I think you want to ask about the steps of problem solving. The basic steps are state the problem, form a hypothesis, test the hypothesis, collect the data, analyze the data and draw conclusions.
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
Answer:
12 valence electrons
Explanation:
Number of valence electrons: 2 carbons (2 x 4 valence electrons= 8e-) and 4 hydrogens (4 x 1 valence electron = 4 e-) added up gives us 12 valence electrons to work with: Counting the bonds we have made shows that we have used up 10 of the 12 valence electrons leaving us with 2 to complete the octets.
