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.
You now know the number of moles of each substance needed in a theoretical perfect reaction. If you want to know the number of grams needed of each substance, you can multiply by the molar mass of each substance: NaOH = 2.10 mol * 39.997 g/mol = 83.9937g. Mg (OH)2 = 1.05 mol * 58.319 g/mol = 61.23495g.

In the equation #Mg(s) + 2HCl(aq) -> MgCL_2(aq) + H_2(g)#, what mass of hydrogen will be obtained if #100# #cm^3# of 2.00 mol #dm^-3# #HCl# are added to 4.86 g of magnesium? Solid iron reacts with sulfuric acid to produce iron (ll) sulfate and hydrogen gas.
27 Οκτ 2022 · 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? \(\ce{MgCl2}(aq)+\ce{2NaOH}(aq)\rightarrow \ce{Mg(OH)2}(s)+\ce{2NaCl}(aq)\)
21 Νοε 2020 · Write a balanced molecular equation describing each of the following chemical reactions. Solid calcium carbonate is heated and decomposes to solid calcium oxide and carbon dioxide gas. Gaseous butane, C 4 H 10, reacts with diatomic oxygen gas to yield gaseous carbon dioxide and water vapor.
25 Ιαν 2016 · What is a limiting reagent? Answer: The limiting reagent is the reagent in deficiency in a chemical reaction. Explanation: Consider a combustion reaction (of say methane): CH 4(g) + 2O2(g) → CO2(g) +2H 2O(g) There is lots of oxygen in the atmosphere; there is limited methane in your gas bottle. Clearly, here methane is the limiting reagent.
