Answer:
The best available answer here is particle velocity equals the boiling point.
Explanation:
Answer:
False. The balance equation for the redox reaction is:
2Fe + 3CuSO₄ → 3Cu + Fe₂(SO₄)₃
Explanation:
Let's think the half reactions:
Fe → Fe³⁺ + 3e⁻
The Fe increase the oxidation state. This is the oxidation, where Fe changes from 0 to +3
Cu²⁺ + 2e⁻ → Cu
This is the reduction. Cu changes from 2+ to 0
We multiply the half reaction x2 and x3 to balance the electrons
2Fe → 2Fe³⁺ + 6e⁻
3Cu²⁺ + 3e⁻ → 3Cu
And we sum both
2Fe + 3Cu²⁺ + 6e⁻ → 3Cu + 2Fe³⁺ + 6e⁻
The electrons are cancelled, so the balance reaction is:
2Fe + 3CuSO₄ → 3Cu + Fe₂(SO₄)₃
Answer:
3. number of protons
Explanation:
In a neutral atom, the total number of electrons in such an atom is equal to the number of protons.
There are three fundamentally known sub-atomic particles in an atom. They are:
Protons which are positively charged and are contained in the nucleus
Neutrons which do not carry any charges
Electrons which are negatively charged.
Both of protons and neutrons are located in the nucleus.
Atoms are charged by gaining of losing electrons.
When an atom gains electrons, they become negatively charged and the number of electrons in them becomes more than that of protons.
When they lose electrons, they become positively charged as the the number of protons is more.
Neutral atoms have equal number of protons and electrons in them.
