Always use the upper case for the first character in the element name và the lower case for the second character.Examples: Fe, Au, Co, Br, C, O, N, F. Compare: teo - cobalt và CO - carbon monoxide
To enter an electron into a chemical equation use - or e khổng lồ enter an ion, specify charge after the compound in curly brackets: +3 or 3+ or 3.

Simply look at the coefficients in the balanced equation. The coefficient for HCl is 2 và that for K2SO3 is 1, so the mole ratio is 2 : 1 (2). Find moles of HCl and then since the mol ratio of HCl : K2SO3 is 2:1 (as determined above), we can find moles K2SO3 and then grams of K2SO3. moles HCl = 26.5 ml x 1 L/1000 ml x 3.0205 mol/L = 0.08800 moles HCl moles K2SO3 = 0.0800 mol HCl x 1 mol K2SO3 / 2 mol HCl = 0.0400 moles K2SO3 needed mass K2SO3 needed = 0.0400 mol K2SO3 x 158 g/mol = 6.32 g K2SO3 needed (3 sig.
