Question

Cu(NO3)2+H2SiO3=? Cu(NO3)2+Na3PO4=?

Answer 1

64+14*2+16*3+1*2+28*1+16*3=218
64+14*2+16*3+23*3+31*1+16*4=304

Answer 2

Cu(NO3)2 + H2SiO3

The reaction between Cu(NO3)2 and H2SiO3 is not a well-known or commonly discussed reaction. Therefore, it is difficult to provide a definitive answer without more information or context. However, based on the available search results, it seems that there is no specific information regarding the reaction between Cu(NO3)2 and H2SiO3.

Cu(NO3)2 + Na3PO4

The reaction between Cu(NO3)2 and Na3PO4 can be determined by examining the chemical formulas of the compounds involved. Cu(NO3)2 is copper(II) nitrate, and Na3PO4 is sodium phosphate.

When copper(II) nitrate reacts with sodium phosphate, a double displacement reaction occurs. The copper(II) cation (Cu2+) from Cu(NO3)2 combines with the phosphate anion (PO43-) from Na3PO4 to form copper(II) phosphate (Cu3(PO4)2). The sodium cation (Na+) from Na3PO4 combines with the nitrate anion (NO3-) from Cu(NO3)2 to form sodium nitrate (NaNO3).

The balanced chemical equation for the reaction is:

Cu(NO3)2 + 2Na3PO4 → Cu3(PO4)2 + 6NaNO3.

Please note that the reaction may be influenced by various factors such as temperature, concentration, and reaction conditions.
