Answer:
Explanation:
1 mole of methane = C + H4 = 12 + 4 = 16
32 grams of methane is 32/16 = 2 moles.
1 moles of methane contains 4 moles of hydrogen (CH4). Note the 4 in CH4
2 moles of methane = 8 moles of hydrogen.
H2O has 2 moles of hydrogen
Each mole of water contains 2 moles of hydrogen.
8 moles of hydrogen / 2 moles = 4 moles of water.
Answer:
The mass of oxygen gas required to produce 65.75 grams of steam is approximately 162.2 grams
Explanation:
From the question, we have the following chemical reaction equation;
2C₃H₁₈(l) + 25O₂ (g) → 16CO₂(g) + 18H₂O (g)
The molar mass of oxygen, O₂ = 32 g/mol
The molar mass of steam, H₂O = 18.01528 g/mol
25 moles of oxygen are required to produce 18 moles of steam
Therefore, according to Proust's law of definite proportions;
(32 × 25) g of oxygen are required to produce (18 × 18.01528) g of steam
65.75 g of steam will be produced by (32 × 25)/(18 × 18.01528) × 65.75 g ≈ 162.2 g of oxygen O₂.
B because it is the lightest there for it should speed up faster
All particles (atoms and molecules) of matter have kinetic energy because they are always in motion.
A measure of the kinetic energy of particle motion within a substance is temperature. If the particles move faster, they have more kinetic energy, and the substance has a higher temperature
