Answer:
you can explore the structure of atoms as you add protons, neutrons, or electrons to a model and the name of the element you have created
Explanation:
Bones are made up of a framework of a protein called collagen , with a mineral called calcium phosphate that makes the framework hard and strong. Bones store calcium and release some into the bloodstream when it's needed by other parts of the body.
Chemical reactions involve the breaking of bonds and forming new bonds. All chemical reactions involves forming of new substances. For this, stuation, it is evident that a chemical reaction occur because a precipitate formed. Therefore the correct answer is stated in statement 1.
First we have to establish the chemical reaction. As a result of adding N<span>a2CO3 and AgNO3 products formed are NaNO3 and Ag2CO3. NaNO3 is a soluble substance when dissolved in water.
As a general rule, most Ag, Pb and Hg(I) compounds are considered insoluble. Ag2CO3 is insoluble in water hence the reaction given forms a precipitate. </span>
2HCL + __ Zn --> ZnCl2 + H2
i think that's right, not exactly sure.
