In the following equation, what are the reactants: nahco3 + hcl? nacl + h2o + co2
a. nahco3 and hcl
b. nahco3 and nacl
c. hcl and nacl
d. nacl, h2o, and co2

NaHCO3, HCl                 is the answer for sure

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
