Answer:
Explanation:
Thomas is incorrect because acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
Answer:
answer is 34.996 or 35 grams
Explanation:
Br2 + AlCl3
mass 34.996 29.2
RFM 160 133.5
moles 0.2187 0.2187
The combustion of Methane produces CO₂ and water;
CH₄ + 2 O₂ → CO₂ + 2 H₂O
According to balance equation,
1 Mole of CH₄ on combustion give = 2 Moles of H₂O
So,
2 Moles of CH₄ will produce = X Moles of H₂O
Solving for X,
X = (2 Moles × 2 Moles) ÷ 1 Mole
X = 4 Moles
Result:
4 Moles of H₂O is produced on combustion of 2 Moles of CH₄.
Answer:
Particles of the substance are in liquid state will gain kinetic energy between positions C and D.
Explanation:
Problem it tells us that between B an C the substance is solid, but I would say that is solid between A and B while between B and C it is a melting process in which particles will gain energy to transform from solid to liquid.
Now between C and D the particles of the liquid will receive energy which is transformed in kinetic energy so the participles will move faster.
Between D and E the particles the energy received is spent by the particles to pass from liquid state to vapors state.
