although this seems hard but Na2CO3 have both ionic bound and covalent bound cause it's easy since Na (sodium) is metal and C(carbon) and (oxygen) are nonmetal its obvious that it makes an ionic bound. the formula has covalent bound because there are two nometals.
hope that help

All compounds with Na (sodium) are ionic

∙ 14y agoA quick Google search returned page 135, section 1.1.3 of 'Inorganic Chemistry' by Egon Wiberg, Nils Wiberg, and Arnold Frederick Holleman. It reveals that a bond between two sodium atoms results in a metallic bond:
Na+ [:]2- Na+
