Answer:
The standard enthalpy of formation is the energy that would be involved if one mole of the substance were to be formed from its elements that were at standard conditions of temperature and pressure which are 25 degrees C and one atm pressure.
Step-by-step explanation:
Dividing by 2, we have S/2=lw+lh+wh. After that, we subtract lh from both sides to get S/2-lh=lw+wh. Next, we divide both sides by w to get (S/2)/w=l+h. Next, we divide by S/2 to get 1/w=(l+h)/(S/2). Lastly, we multiply by w and divide by (l+h)/(S/2) to get w=(S/2)/(l+h)

Answer:
all are functions except Relation 2
Step-by-step explanation:
If any input value (first of an ordered pair) is used more than once, the relation is not a function. Output values can be used as often as you like.
Only Relation 2 is not a function.
Step-by-step explanation:
Calculate the the total number of the boxes. We can calculate it by counting number of the rows and the number of the columns and then multiplying it.
Total number of rows = 10
Total number of columns = 10
Total boxes = 100
Shaded boxes = 72
We calculate %age by,
=> Selected boxes/Total boxes x 100
=> 72/100 x 100
=> 72%
