Answer:
Explanation:
The cation contains 51 protons and 48 electrons. The electrons are only lost not protons, so the element which corresponds to atomic number 51 is the cation which is Antimony (Sb).
Also, the charge on the cation is 51 - 48 = 3
This is because neutral atom contains the same number of electrons as protons.
Given the anion has one-third protons as cation which means thta:
Number of protons in anion = 
This corresponds to chlorine atom. The electrons are 1 greater than protons means that it has gain 1 electron.
So,
Sb Cl
3 1
Cross multiply the valency.
So, formula is
Answer:
Al(NO₃)₃ + (NH₄)₃PO₄ —> AlPO₄ + 3NH₄NO₃
The coefficients are: 1, 1, 1, 3
Explanation:
__Al(NO₃)₃ + __(NH₄)₃PO₄ —> __AlPO₄ + __NH₄NO₃
The above equation can be balance as illustrated below:
Al(NO₃)₃ + (NH₄)₃PO₄ —> AlPO₄ + NH₄NO₃
There are 12 atoms of H on the left side and 4 atoms on the right side. It can be balance by writing 3 before NH₄NO₃ as shown below:
Al(NO₃)₃ + (NH₄)₃PO₄ —> AlPO₄ + 3NH₄NO₃
Now the equation is balanced.
The coefficients are: 1, 1, 1, 3
First you need to know what is a semantic memory
Semantic memory, is a more structured record of facts, meanings, concepts and knowledge about the external world that we have acquired.
So ,The element which is a semantic memory is learning from her father that salt water is more dense than fresh water.
Hope this helped :)
