Computing molar mass step by step; First, compute the number of each atom in C 7 H 1602: C: 7, H: 1602. Then, lookup atomic weights for each element in periodic table: C: 12.0107, H: 1.00794

Heptane or n-heptane is the straight-chain alkane with the chemical formula H 3 C (CH 2) 5 CH 3 or C 7 H 16. When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale (the 100 point is 100% iso-octane).

逐步计算摩尔质量; 首先，计算 c 7 h 1602 (s) 中每个原子的数量： c: 7, h: 1602. 然后，查找元素周期表中每个元素的原子量： c: 12.0107, h: 1.00794 现在，计算原子数与原子量的乘积之和：

A chiral diol with the molecular formula C7H1602 is oxidized by PCC in CH2Cl2 to an achiral compound with the molecular formula C7H1202. Which of the following would satisfy these facts? a.

例如，氢 (H2) 与氧 (O2) 反应生成水 (H2O)，化学方程式为： 然而，这个方程不平衡，因为方程两边每种元素的原子数不同。 平衡的化学方程式遵循质量守恒定律，该定律规定物质在化学反应中既不会产生也不会消失。 这是最直接的方法。 它涉及查看方程并调整系数以获得方程两边每种类型原子的相同数量。 最适合：具有少量原子的简单方程。 过程：从最复杂的分子或元素最多的分子开始，调整反应物和产物的系数，直到方程平衡。 计算两侧 H 和 O 原子的数量。 左边有2 …
