Answer:
The limiting reactant is the covers.
We are left with 3750 sheets of lined paper, 1125 sheets of graph paper and 25 staples.
Explanation:
the reaction is:
B - book
C - cover
Sl = sheet of lined paper
Sg - sheet of graph paper
St - staple
1B = 2C + 50Sl + 25Sg + 3St
We have covers for 150/2 = 75 books
We have lined paper for 7500/50 = 150 books
We have graph paper for 3000/25 = 120books
We have Staples for 250/3 = 83.(3) books, so for 83 books as we cannot make 1/3 of a book.
Because we only have covers for 75 books, covers are the limiting reactant.
After making 75 books we are left with:
0 covers
7500 - 75*50 = 3750 sheets of lined paper
3000 - 75*25 = 1125 sheets of graph paper
250 - 75*3 = 25 staples
Answer:
0.125 atm
Explanation:
From the question,
Applying boyles law
PV = P'V'................................. Equation 1
Where P = Initial pressure, V = Initial volume, P' = Final pressure, V' = final Volume.
make P' the subject of the equation
P' = PV/V'............................. Equation 2
Given: P = 97.5 atm, V = 90 mL = 0.09 L, V' = 70 L.
Substitute these values into equation 2
P' = 97.5×0.09/70
P' = 0.125 atm
Ok so look at the first one they gave you. 0.40 is 40%. They got that by moving the decimal two times.
The possible structure for given Chemical formula is given below, It is asked that the Nitrogen atom is connected to only one atom. As, nitrogen is involved in making three bonds so it is only possible for Nitrogen to make three bonds with Carbon atom having the capacity of forming four bonds. The possible structure is
Acetonitrile. In which N is connected to Carbon atom through triple bond as shown below,
Result: In current structure in which N is attached to only one atom, there is no double bond. So, the answer is
ZERO.
