In the reaction mg(s) + 2h2o(l) --> mg(oh)2(s) + h2(g), what is the oxidation state of each h in h2(g)? a. +2 and –2 b. –1 and +1 c. +1 d. 0 no idea how to do this. i know its not d because that's for magnesium

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

Which element has the lowest electronegativity? calcium(ca) gallium(ga) selenium(se) bromine(br)

Which of the following is most likely true about water in chemical solutions?
