If 32 grams of MgCl2 react. How many grams of HCl will be formed in the reaction? H2SO4 + MgCl2 -> 2 HCl + MgSO4 Reaction Yield: The reaction yield refers to the process of calculating the amount of product that will be obtained from a chemical re...
How many grams of NaOH can be produced from 120 grams of Na2O and excess H2O in the following reaction? Na2O(s)+H2O(l)→2NaOH(aq) Stoichiometry :The reaction stoichiometry represents the relationship between the amount of reactants...
To do this, you need to find a way to relate the mass of a compound (salt) to the number of moles of that compound. The molar mass of elements tells you the molar mass of a compound, so you can figure this out. Molar Mass Definition ...
If water is present, many of them are water soluble (aq), but others aren't and you will eventually learn which ones are which.So look again at your MgCl2 - what sort of bonds are those? Logged Arkcon Retired Staff Sr. Member Posts: 7367 Mole Snacks: +533/-147 Re: How do ...
In this example, you add a "2" in front of the hydrochloric acid and a "2" in front of the water to balance the equation. The reaction is now Mg(OH)2 + 2HCl –> MgCl2 + 2H2O. 2. Find Molecular Weight Convert reactant quantities to moles. Use a periodic table to find the ...
3.) if a table contains 110 mg of Mg(OH)2 and 550mg CaCO3 how many moles of HCL would theoretically be neutralized. *for this one do i just convert the mass into the mols of HCL and add them up. Thanks Chemistry news on Phys.org New hybrid catalyst developed for clean oxygen pr...
