Answer:
The answer to your question is:
Explanation:
Data
Ion charge of 2- and 18 electrons
Process
a) From which atom does this ion form?
If an Ion has a negative charge, it means that it has more electrons than the neutral atom. So, it the ion has 18 electrons, it means the neutral atom has 16 electrons.
In the periodic table we find that the atom with 16 electrons is Sulfur.
B) How do you know?
I have explained it.
An ion with a negative charge means that it gained the number of negative charges compare with the neutral atom.
1. put a 2 in front of H on the H2O
2. put a 2 in front of KCL and KF
3. put a 2 in front of HCl
4. put a 2 in front of AgNO and 2 in front of Ag
5. put a 2 in front of HCl and 2 in front of H2O
I can write these out if you need me to
The mass lost in the process is 1.4 * 10^-5Kg.
<h3>What is the Einstein equation?</h3>
The Einstein equation is able to relate the mass lost to the energy that is evolved in a nuclear process.
Given that;
E = Δmc^2
Δm = E/c^2
Δm = 1.26 × 10^12 J/( 3 * 10^8)^2
Δm = 1.4 * 10^-5Kg
