Hey Everyone

Half yearlies for my school are starting this Tuesday and I realized for Chemistry that I'm having trouble with a couple of the syllabus dot points, mainly Lewis Dot points and balancing equations. Can anybody help me? And also I can't find in my books about, for example, when water + metal ----> something + something and so on and so forth cause I think we're supposed to know those sorts of things

I'll make you a computorised rainbow cupcake if anybody helps me ^^

Here are the reactions that you were talking about:

metal + oxygen ---> metal oxide
metal + water ---> metal hydroxide + hydrogen
metal + steam ---> metal oxide + hydrogen
metal + acid ---> salt + hydrogen
