The electron configuration 1s22s22p6323p2
is the element Silicon.
Answer:
Proton - Positive charge
Neutron - No charge
Electron - negative charge
Explanation:
An atom is the smallest particle of matter that takes part in a chemical reaction.
It is made up of three fundamental subatomic particles.
- Protons are the positively charged particles in an atom.
- Neutrons do not carry any charges and are neutral
- Electrons are negatively charged
Both the protons and neutrons occupy a tiny center where the mass of the atom is concentrated. The region is called the nucleus.
The equation which we are required to complete can be completed as follows;
- AgNO3 + KCl ==> KNO3 + AgCl
<h3>Electrochemical series;</h3>
Most substitution reactions involve displacement of metals and non-metals.
The possibility of a substitution reaction to occur is sometimes dependent on the order of preference of the metals in the activity series.
On this note, In the reaction between AgNO3 and KCl, potassium, K displaces silver, Ag and the products of the reaction are; KNO3 and AgCl

Balanced chemical reaction: 2K(s) + 2H₂O(l) → 2KOH(aq) + H₂(g).
KOH is inorganic compound p<span>otassium hydroxide, a strong base.
H</span>₂ is hydrogen gas.
In balanced chemical reaction number of atoms on both side of chemical reaction must be same. There are two potassium atoms, four hydrogen atoms and two oxygen atoms on both side of reaction.
Answer : The final energy of the system if the initial energy was 2000 J is, 3500 J
Solution :
(1) The equation used is,
where,
= final internal energy
= initial internal energy
q = heat energy
w = work done
(2) The known variables are, q, w and
initial internal energy = = 2000 J
heat energy = q = 1000 J
work done = w = 500 J
(3) Now plug the numbers into the equation, we get
(4) By solving the terms, we get
(5) Therefore, the final energy of the system if the initial energy was 2000 J is, 3500 J
