Answer:
The answer to your question is 0.5 moles
Explanation:
Data
moles of Glucose = ?
moles of carbon dioxide = 3
Balanced chemical reaction
6CO₂ + 6H₂O ⇒ C₆H₁₂O₆ + 6O₂
Process
To solve this problem, use proportions, and cross multiplication.
Use the coefficients of the balanced equation.
6 moles of CO₂ ----------------- 1 mol of C₆H₁₂O₆
3 moles of CO₂ ---------------- x
x = (3 x 1) / 6
-Simplification
x = 3/6
-Result
x = 0.5 moles of Glucose
Answer:
Radiation
Explanation:
Radiation is the transfer of energy in waves. Heat from a campfire is one example.

The relation between activation energy, rate constant and temperature is given by Arrhenius equation
Arrhenius equation is
ln (K2/ K1) = Ea / R (1/T1- 1/T2)
K2 = 1×10−3s−1 T2 = 525 ∘C = 798 K
K1 = 1×10−4s−1 T1 = 485 ∘c = 758 K
Ea = ?
R = gas constant = 8.314 J / mol K
ln (K2/ K1) = ln (10^-3 / 10^-4) = 2.303 = Ea /8 .314 (1/758 - 1 / 798)
2.303 = Ea / 8.314 (0.00132 - 0.00125)
Ea = 2.303 X 8.314 / (0.00132 - 0.00125) = 273530.6 J / mole
Ea = activation energy = 273.531 kJ / mole
Answer:
1.02 grams
Explanation:
The reaction between Na₃PO₄ and BaCl₂ is:
2Na₃PO₄(aq) + 3BaCl₂(aq) → Ba₃(PO₄)₂(s) + 6NaCl(aq)
We need to find the number of moles of Na₃PO₄ and BaCl₂:
Now, we need to find the limiting reactant:
We have that it is needed 0.0033 moles of Na₃PO₄ to react with BaCl₂ and we have 0.01 moles of Na₃PO₄, so the limiting reactant is BaCl₂.
The number of moles of Ba₃(PO₄)₂ is:
Finally, the mass of Ba₃(PO₄)₂ is:
Therefore, should be obtained 1.02 grams of the precipitate.
I hope it helps you!
