Required fields are marked *, Metal Compound A Reacts With Dilute Hydrochloric Acid To Produce Effervescence The Gas Extinguishes A Candle Write A Balanced Chemical Equation For The Reaction If Compounds Formed Calcium Chloride. Whenever we balance an eqaution you have to change the nuer of molecules used represented by the big nuers before a molecule e.g 2HCl. As aluminium has three electrons in its outer shell, the reaction requires a ratio of two aluminium molecules to six hydrochloric acid molecules.

First, write the balanced equation: 2Al + 6HCl --> 2AlCl3 + 3H2. The gas thus formed is an effervescent carbon dioxide gas when calcium carbonate reacts with hydrochloric acid. commented Mar 6, 2019 by Sampauljose (10 points) +1. 2 H C l ( a q ) + M g ( s ) → M g C l 2 ( a q ) + H 2 ( g ) (c) Dilute sulphuric acid reacts with aluminium powder to produce aluminium sulphate and hydrogen gas. Aluminum metal reacts with dilute hydrochloric acid, HCl, to form hydrogen gas and a solution of aluminum..? {eq}2 Al + 6 HCl \to 2 AlCl_3 + 3 H_2 {/eq} This is because, by multiplying the required number of moles to the molar mass of the substance, we easily acquire the mass that must be weighed out for the substance. Dilute hydrochloric acid reacts with sodium carbonate. Answer Save. Calculate the mass (in grams) of the sample....
