The reason people describe water as a universal solvent is because it dissolves almost anything.
I think it is with screens l, chemicals, and filters
I hope this helped
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
<span>The balanced equation is: C3H8 + 5 O2 = 3 CO2 + 4 H2O
</span>1) first step is to<span> determine the molar mass you have to consult the periodic table and see the atomic mass of each element. If the element is repeated, for example 3 times, you multiple the atomic mass per 3.
C3H8= 12 x 3 + 1*8
= 44 g/mol
2)convert grams to moles so that everything will be in same unit.</span>
<span>moles are calculated by dividing mass by molar mass.
moles of C3H8= 295g / 44 g/mol
= 6.705 mol
3)By looking at the balanced equation, you can see that 1 mol of C3H8 will produce 3 moles of CO2. So if you have 6,705 moles, you will obtain x moles of CO2:
1 C3H8--------3 CO2
6,705----------x of CO2
x= 20,115 mol of CO2
</span>
4) At STP(<span>Standard Temperature and Pressure)</span> 1 mole of gas is equivalent to 22.4 liters.
1 mol of CO2-----22,4
20,115 -------------x liters
x= 20,115 x 22,4 =
450,6 liters.
