Baking soda (sodium bicarbonate) is a
compound commonly used in baked
goods, as a deodorizer in refrigerators,
and as an antacid, Commercial quantities
of baking soda are produced by mixing
soda ash dissolved in water with carbon
dioxide. Baking soda precipitates as a
solid from this method:
Na2CO3 + CO2 + H20 - 2 NaHCO3
How many grams of soda ash would be
needed to produce 1.00 kg of sodium
bicarbonate?

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.
