Answer:
21.6 g
Explanation:
The reaction that takes place is:
First we<u> convert the given masses of both reactants into moles</u>, using their <em>respective molar masses</em>:
- 9.6 g CH₄ ÷ 16 g/mol = 0.6 mol CH₄
- 64.9 g O₂ ÷ 32 g/mol = 2.03 mol O₂
0.6 moles of CH₄ would react completely with (2 * 0.6) 1.2 moles of O₂. As there are more O₂ moles than required, O₂ is the reactant in excess and CH₄ is the limiting reactant.
Now we <u>calculate how many moles of water are produced</u>, using the <em>number of moles of the limiting reactant</em>:
- 0.6 mol CH₄ *
= 1.2 mol H₂O
Finally we<u> convert 1.2 moles of water into grams</u>, using its <em>molar mass</em>:
- 1.2 mol * 18 g/mol = 21.6 g
Answer:
¿Cuál es la reaccion quimica de la respiracion celular?
La respiración celular es una reacción exergónica, donde parte de la energía contenida en las moléculas de alimento es utilizada por la célula para sintetizar ATP. ... Aproximadamente el 40% de la energía libre emitida por la oxidación de la glucosa se conserva en forma de ATP.

Answer:
Charles's law
Explanation:
The expression:
V1/T1 = V2/T2
represents Charles's law
The law states that "the volume of a fixed mass of a gas varies directly as its absolute temperature if the pressure is constant".
So,
V1/T1 = V2/T2
Pressure and the number of moles are constant
V and T are the volume and temperature
1 and 2 are the initial and final states.
Answer:
a. C₄H₁₀/O₂ = 2:13 (example)
b. O₂/CO₂ = 13:8
c. O₂/H₂O = 13:10
d. C₄H₁₀/CO₂ = 2:8
e. C₄H₁₀/H₂O = 2:10
Explanation:
2C₄H₁₀ + 13O₂ ⟶ 8CO₂ + 10H₂O
The molar ratios are the same as the coefficients in front of the formulas.
Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification. So I believe your answer would be A.
