Balancing step by step using the inspection method. Let's balance this equation using the inspection method. First, we set all coefficients to 1: 1 CO 2 + 1 Mg (OH) 2 = 1 Mg (HCO 3) 2. For each element, we check if the number of atoms is balanced on both sides of the equation.
Enter the formula of a chemical compound to find the oxidation number of each element. A net ionic charge can be specified at the end of the compound between { and }. For example: ZnCl4{2-} or NH2NH3{+}. Enter just an element symbol to show the common and uncommon oxidation states of the element.
To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
Enter an equation of a redox chemical reaction and press the Balance button. The balanced equation will be calculated along with the oxidation states of each element and the oxidizing and reduction agents. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
14 Αυγ 2020 · What mass of sodium hydroxide, NaOH, would be required to produce 16 g of the antacid milk of magnesia [magnesium hydroxide, Mg(OH) 2] by the following reaction? \(\ce{MgCl2}(aq)+\ce{2NaOH}(aq)\rightarrow \ce{Mg(OH)2}(s)+\ce{2NaCl}(aq)\)
From the solubility data, Mg(OH)2 is by far less soluble than MgCO3. From the Ksp data, any way you look at them, the solubility product of Mg(OH)2 is smaller than for MgCO3, indicating a lower solubility. So, no conflict.
Learning Objectives. Use stoichiometry to calculate the amount (in moles or grams) of a particular substance produced or used in a chemical reaction. Use stoichiometry to determine molecular formulas. A balanced chemical equation provides a great deal of information in a very succinct format. Chemical formulas provide the identities of the ...
