Answer:
Mass of butane = 1.87 g
Explanation:
Form a balanced chemical equation for the reaction stated:
C₄H₁₀ + 13/2 O₂ → 4CO₂ + 5H₂O
Number of moles of CO₂
From the equation,
1 mol C₄H₁₀ : 4 mol CO₂
0.085 mol C₄H₁₀ : 0.34 mol CO₂
Mass of butane
B reflecting light because the mirror interacts with the light reflection
Answer:
An electron cloud model is different from the older Bohr atomic model by Niels Bohr. Bohr talked aboutelectrons orbiting the nucleus. ... Theelectron cloud model says that we cannot know exactly where an electron is at any given time, but the electronsare more likely to be in specific areas.
