There are two types of elements, sodium (Na) and chlorine (Cl) in NaCl and they exist as ions: Na+ and Cl- ions
2SnCl4 has 10 atoms. There are two molecules of the equation, each with 1 Sn atom and 4 CL atoms.
Single replacement A+
2NaCl + H2SO4 = Na2SO4 + 2HCl
It is a double replacement reaction, also called a double displacement reaction.
All atoms of one kind share common properties
2SnCl4 has 10 atoms. There are two molecules of the equation, each with 1 Sn atom and 4 CL atoms.
18 carbon atoms
The equation given is correctly balanced, because it contains the same numbers of each kind of atoms in the reactants as in the products.
Because each side of the equation shows two chlorine atoms, two sodium atoms, and two iodine atoms, and these are the only atoms present.
Single replacement A+
single replacment
2NaCl + H2SO4 = Na2SO4 + 2HCl
It is a double replacement reaction, also called a double displacement reaction.
Balanced equation for Sodium and Chlorine is: 2Na + Cl2 --> 2NaCl
2NaCl + Ni (for A+)
It usually represent the amount of atoms in a molecule, i.e. Na2CO3 + 2HCl --> 2NaCl + CO2 +H2O So, in the first compound, there are 2 sodium atoms, one carbon atom and 3 oxygen atoms. In water, there is one hydrogen atom and 2 oxygen atoms..
There is only one (chemical) kind of carbon atoms, they all are alike.
