How do electric charges occur?

Chemistry
1 answer:
blondinia [14]3 years ago
6 0

Answer:

In an atom of matter, an electrical charge occurs whenever the number of protons in the nucleus differs from the number of electrons surrounding that nucleus. If there are more electrons than protons, the atom has a negative charge. If there are fewer electrons than protons, the atom has a positive charge.

Na3PO4 + AlBr3 ----&gt; ?
Sati [7]
Na₃PO₄(aq)+AlBr₃(aq)→3NaBr(aq)+AlPO₄(s)

This is a double replacement reaction.  You can tell that there has to be 3NaBr molecules since there are 3 Na atoms in sodium phosphate and 3 Br atoms in aluminum bromide.  We also know that Na has an oxidation number of +1 which means PO₄ needs to have an oxidation number of -3 while Br has an oxidation number of -1 which means Al has an oxidation number of +3.  That means that Al³⁺ and PO₄³⁻ can from AlPO₄  
I hope this helps.  Let me know if anything is unclear.
