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
![= \frac{mass}{molar \: mass}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7Bmass%7D%7Bmolar%20%5C%3A%20mass%7D%20)
![= \frac{15}{12 + 2(16)}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B15%7D%7B12%20%2B%202%2816%29%7D%20)
![= 0.34 \: mol](https://tex.z-dn.net/?f=%20%3D%200.34%20%5C%3A%20mol)
From the equation,
1 mol C₄H₁₀ : 4 mol CO₂
0.085 mol C₄H₁₀ : 0.34 mol CO₂
Mass of butane
![= number \: of \: moles \times molar \: mass](https://tex.z-dn.net/?f=%20%3D%20number%20%5C%3A%20of%20%5C%3A%20moles%20%5Ctimes%20molar%20%5C%3A%20mass)
![= 0.085 \times (12 + 10(1))](https://tex.z-dn.net/?f=%20%3D%200.085%20%5Ctimes%20%2812%20%2B%2010%281%29%29)
![= 1.87 \: g](https://tex.z-dn.net/?f=%20%3D%201.87%20%5C%3A%20g)
Answer:
No (If we are talking about pure water)
Explanation:
Water is a compound. Each molecule is made up of only 2 Hydrogen atoms and 1 Oxygen atom.
According to the Aufbau principle, , electrons orbiting one or more atoms fill the lowest available energy levels before filling higher levels (e.g., 1s before 2s).
A or C for number 4 and for number 5 it could be C
Answer:
One kind is called living things. Living things eat, breathe, grow, move, reproduce and have senses. The other kind is called nonliving things. Nonliving things do not eat, breathe, grow, move and reproduce.
