Alab group reacts sodium oxide (na2o) with hydrochloric acid (hcl) to produce sodium chloride (nacl) and water (h2o). when writing their lab report, they come up with the following equation to represent the reaction: na2o + hcl -> nacl + h2o does this equation satisfy the law of conservation of matter? why or why not? a) yes, since there are 5 reactant atoms and 5 product atoms. b) yes, since there is a subscript of 2 on both sides on the equation. c) no, since there are two sodium atoms as reactants, but only one sodium atom as a product. d) no, since there is a liquid and a solid as reactants, but a gas and a solid as a product.

 Na₂O + HCl →   NaCl + H₂O

Does the equation above  satisfy the law  of  conservation  of matter?

No, since there are two sodium atoms  as reactants  but   only   one sodium atom  as product

 Explanation

According  to the law  of mass conservation  of matter the  total number of atoms  of reactant  must be  equal  to total   number  of  product.

For equation  given to satisfy the law  of conservation  of matter  you need to balance the equation as below

Na₂O + 2HCl  →  2NaCl  + H₂O

c

Explanation:

Since there are two sodium atoms as reactants, but only one sodium atom as a product, the equation does NOT follow the Law of Conservation of Matter. A sodium atom can not be destroyed in a chemical reaction, therefore the group needs to properly balance their equation so that it follows the Law of Conservation of Matter.

i'm assuming that the correct answer is indeed the first one/ "a"..

yes
