Write a balanced chemical equation for this reaction . Solution: If the question says solid, we need to write (s) next to the compound, liquid means (l), gaseous means…

When iron rusts, solid iron reacts with gaseous oxygen to form solid iron(III)oxide. Write a balanced chemical equation for this reaction . Solution: If the question says solid, we need to write (s) next to the compound, liquid means (l), gaseous means (g) and aqueous means (aq). Solid iron is Fe(s). Gaseous oxygen is O2(g)….

Determine the number of moles of hydrogen in 0.0885 mol C4H10 Solution: There are 10 atoms of hydrogen in every molecule of C4H10. Therefore, 1 mol of C4H10 will have 10 moles of hydrogen. 0.0885 mol C4H10 * (10 moles of hydrogen/ 1 mol of C4H10) = 0.885 moles of hydrogen LINKS General Chemistry CourseOnline…

A sugar crystal contains approximately 1.8*1017 sucrose (C12H22O11) molecules. What is its mass in milligrams? Solution: To go from molecules to milligrams, we will first need to convert molecules to moles using Avogadro’s number, then convert moles to grams using Molar Mass of the molecule(C12H22O11) and finally convert grams to milligrams (1g=1000mg).
