Câu 8:
a) Bảo toàn khối lượng: \(m_{O_2}=m_{KClO_3}-m_{rắn}=9,6\left(g\right)\)
\(\Rightarrow n_{O_2}=\dfrac{9,6}{32}=0,3\left(mol\right)\) \(\Rightarrow V_{O_2}=0,3\cdot22,4=6,72\left(l\right)\)
b) Bảo toàn khối lượng: \(m_{rắn}=m_{O_2}+m_P=9,6+9,3=18,9\left(g\right)\)

Bài 5
B= \(\dfrac{2015}{2016+2017+2018}\)+\(\dfrac{2016}{2016+2017+2018}\)+\(\dfrac{2017}{2016+2017+2018}\)
Ta có:\(\dfrac{2015}{2016}\)>\(\dfrac{2015}{2016+2017+2018}\),\(\dfrac{2016}{2017}\)>\(\dfrac{2016}{2016+2017+2018}\),\(\dfrac{2017}{2018}\)>\(\dfrac{2017}{2016+2017+2018}\)

Bài 5:
Ta có:
\(B=\dfrac{2015+2016+2017}{2016+2017+2018}\)
\(B=\dfrac{2015}{2016+2017+2018}+\dfrac{2016}{2016+2017+2018}+\dfrac{2017}{2016+2017+2018}\)
Vì \(\dfrac{2015}{2016}>\dfrac{2015}{2016+2017+2018}\)
\(\dfrac{2016}{2017}>\dfrac{2016}{2016+2017+2018}\)
\(\dfrac{2017}{2018}>\dfrac{2017}{2016+2017+2018}\)
\(\Rightarrow A>B\)
