Description Try to insert a chemical equation like this \ce{H2}+\ce{O2}\ce{->[Heating]}\ce{H2O}, The text intersects with the arrow as follows: Actual Behavior The text intersects with the arrow Expected Behavior I expected it to be rend...
Whenchemical equilibriumoccurs in a reaction, the double arrow (⇋) is used instead of the single arrow. For example, liquid water dissociates to form hydronium ions (H3O+) and hydroxide ions (OH−). These ions exist in equilibrium with water molecules. The equation is 2H2OH2O⇋H3O++...
Write the proper word equation to express the following chemical reaction: 3Li (s) + AuCl_3 (aq) \rightarrow 3LiCl (aq) + Au (s). Give an example of a word equation, a formula equation, and a chemical equation. Fill in the blank in the following chem...
A. products to reactants. B. reactants to products. C. catalysts to reactants. D. products to catalysts. 相关知识点: 试题来源: 解析 B。解析:在化学反应方程式中,箭头是从反应物指向产物。选项 A 方向错误。选项 C 和 D 催化剂不是反应的主要物质,箭头不指向它们。反馈 收藏 ...
In a math equation the value of the left side of the equal sign is the same value as the right side. These values also exist at the same time like a balance. In a chemical equation the atoms on the left side have to be equal to the atoms on the right side of the arrow, but th...

chemical equation is a written statement that uses chemical symbols and chemical formulas instead of words to describe the changes that occur in chemical reactions. the following example, shows the contrast between a word description of a chemical reaction and a chemical equation for the same ...
In a word equation – The reactants and products are separated by an arrow between them. Reactants are written on the left-hand side of the arrow (LHS) with a (+) sign between them. Products are written on the right-hand side of the arrow (RHS) with a (+) sign between them. ...
Left Side of the Equation: Reactants Thereactantsin this chemical reaction are methane and oxygen: CH4and O2. Right Side of the Equation: Products The products of this reaction arecarbon dioxideand water: CO2and H2O. Direction of Reaction: Arrow ...
