Yes, it is. The pencil is still composed of wood and graphite before and after the break, although the physical form is different, of course. If you wanted a comparison, burning the pencil would be a chemical change.
Write the balanced neutralization reaction<span> between H2SO4(</span>sulfuric acid<span>) and </span>KOH(potassium hydroxide<span>) in </span>aqueous<span> solution. 0.150L of 0.470 M H2SO4 is mixed with 0.100L of 0.230 M </span>KOH<span>.</span>
The balanced equation for the combustion of CH₄ is as follows
CH₄ + 2O₂ ---> CO₂ + 2H₂O
stoichiometry of CH₄ to CO₂ is 1:1
therefore molar ratio of CH₄ to CO₂ is 1:1
the number of CH₄ moles combusted - 1.00 mol
number of CO₂ moles formed = number of CH₄ moles reacted
therefore number of CO₂ mol formed - 1.00 mol
mass of CO₂ produced - 1.00 mol x 44 g/mol = 44.0 g
mass of CO₂ produced is 44.0 g
The Yellow River is the most important water resource for the dry north of China, playing an irreplaceable role in economic development, and agriculture. Since 1960 over 14 dams have been constructed on the river for hydroelectric power, which is vital to northern China's infrastructure.
