<span> Na2CO3 + 2HCl = CO2 + H2O + 2NaCl
this is the double displacement reaction
</span><span>2 Na(+) + CO3(-2) + 2H(+) + 2Cl(-) ------> 2Na(+) + 2 Cl(-) + H2O + CO2
</span>2Na+ and 2Cl- are the spectator ions as they appear on the both sides of equation :
so the net ionic equation can be written as :
CO3(-2) + 2H(+) -------------> <span>H2O + CO2</span>
Explanation:
The atoms of one element differs from the atoms of other elements in terms of the number of protons they contain. This is often taken as the atomic number of such an atom.
- The number of proton is the best indicator of the atom one is dealing with.
- Based on this number, elements are categorized into distinct columns and rows on the periodic table.
- The atomic number is the number of protons or positively charge particles in the atom.
II.
It is possible to change the identity of an atom. This is only possible by altering the atomic number of the atom.
Only nuclear reactions have this capability.
When an atom undergoes nuclear reaction that involves change in number of protons, transmutation occurs and a new atom forms.
Answer:
A synthetic element is one of 24 chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, they are called "synthetic", "artificial", or "man-made".
Explanation: hope that helps
Answer:
I think it is iron conducts electricity and heat
It will belong to the metals because metals bond with nonmetals like chlorine to form ionic compounds
