Answer:
The bonds between atoms in the reactants are rearranged to form new compounds in chemical reactions, but none of the atoms disappear and no new ones are formed. As a consequence, chemical equations must be balanced, meaning that the number and kinds of atoms must be the same on both sides of the reaction arrow.
Explanation:
HCl is an acid, C5H5N is a base, Cl is an acid, and HC5H5N is an acid.
Hope this helps! If so, brainliest would be appreciated!
Gases have three characteristic properties: (1) they are easy to compress<span>, (2) they expand to </span>fill<span> their containers, and (3) they occupy far more space than the liquids or solids from which they form. An internal</span>combustion engine<span> provides a good example of the ease with which gases can be compressed.</span>
I’m assuming in this scenario that 2.5 mols of Fe2O3 is reacting with excess reactant. Based on the balanced equation, you can see that there’s a 1:2 ratio between Fe2O3 and Fe. This means that to find the mols of Fe formed, you need to multiply the mols of Fe2O3 by 2.
2.50mol Fe2O3 * 2mol Fe/1 mol of Fe2O3 = 5.00mols Fe.
