Answer:
Explanation:
statinary front is when a cold air mass and a warm air mass but are at a standstill the boundry is called statinary front sorry i could not give you other anwsers
(4) PCl5--> PCl3+ Cl2 is the correct answer because we both have 1 P atom and 5 Cl atoms on both sides, and thus the masses of the elements don't change.
Hope this would help~
Hello!
To calculate the
household concentration of NaOH we need to use the
dilution formula, clearing for M2, as you can see in the equation below:

Now, we input the values from the data we have onto this equation. M1=19,1 M; V1=10 mL; V2=400 mL, and solve the equation to get the result:

So, the
household concentration of NaOH will be 0,48 M
Have a nice day!
Answer:
200 watts
Explanation:
First we have to find total work:
W =F(d)
W = 400J
Then plug that answer into the Power formula.
P = W/(t_f-t-i)
P = 400/2s
P = 200 W
H will definitely be positive because a bond is always more stable than no bond surely if it is a sigma bond.
For G you can't really know because you don't know how much energy is provided by the bond and if it outways the loss in disorder.
The reaction will become more spontaneous with a lower temperature because H tells you the reaction is exotherm
