Using Dimensional AnalysisExplanation:Step 1: Define
[RxN - Balanced] C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
[Given] 150 g O₂
Step 2: Identify Conversions
[RxN] 5 mol O₂ → 3 mol CO₂
[PT] Molar Mass of O - 16.00 g/mol
[PT] Molar Mass of C - 12.01 g/mol
Molar Mass of O₂ - 2(16.00) = 32.00 g/mol
Molar Mass of CO₂ - 12.01 + 2(16.00) = 44.01 g/mol
Step 3: Stoich
[DA] Set up: [tex]\displaystyle 150 \ g \ O_2(\frac{1 \ mol \ O_2}{32.00 \ g \ O_2})(\frac{3 \ mol \ CO_2}{5 \ mol \ O_2})(\frac{44.01 \ g \ CO_2}{1 \ mol \ CO_2})[/tex][DA] Multiply/Divide [Cancel out units]: [tex]\displaystyle 123.778 \ g \ CO_2[/tex]Step 4: Check
Follow sig fig rules and round. We are given 2 sig figs.
123.778 g CO₂ ≈ 120 g CO₂
Why is nuclear energy considered a nonrenewable resource?
Nuclear radiation does not run out.
It comes from radiation from the sun.
Uranium ore is replaced on a geologic timescale.
Uranium replenishes more quickly than it is being used.
Answer:
You could classify nuclear energy as nonrenewable because uranium and similar fuel sources are finite. On the other hand, some people consider nuclear energy renewable because the element thorium and other new technologies may provide infinite fuel needed to power nuclear reactors.

mole-mass problem:
Water decomposes to produce hydrogen gas and oxygen gas. How many moles of oxygen would be produced from 10.0 moles
water? 2 H2O → 2 H2 + O2
Answer:
5.00 mol O₂
Explanation:
2H₂O → 2H₂ + O₂In order to solve this problem we will need to convert moles of water to moles of oxygen. We will do that using the stoichiometric coefficients, as follows:
10.0 mol H₂O * [tex]\frac{1molO_2}{2molH_2O}[/tex] = 5.00 mol O₂Thus 5.00 moles of oxygen would be produced from 10.0 moles of water.

The pH of a solution is 8.7
What is the pOH?
Answer:
pOH = -log[OH – ]
pH + pOH = 14
Explanation:
I did not understand the question but hope this help!
The pH of a solution is 8.7 and pOH is 5.3
What is sum of pH and pOH?The sum of pH and pOH is 14.
pH + pOH = 14
If pH of a solution is 8.7 then pOH is calculated as,
8.7 + pOH = 14
pOH = 14 - 8.7
pOH = 5.3

Calculate the molecular formula of a compound with the empirical formula CH O and a molar mass of 150 g/mol.
A) C2H4O2
B) C3H6O3
C) C4H8O4
D) C5H10O5
E) C6H12O6
The molecular formula : D) C₅H₁₀O₅
Further explanationGiven
The empirical formula CH₂O
The molar mass of 150 g/mol
Required
The molecular formula
Solution
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
(CH₂O)n = 150 g/mol
(12+2.1+16)n = 150
(30)n = 150
n = 5
