Thermal energy is dependent on the mass. If objects have a different mass then they will have a different thermal energies.
I don't know exactly but you can try narrowing down your answers down to A or D but it might be D if the system is random if that even helps and makes sense-
Answer:
The Fehling's Test for non-reducing sugar is an alternative to the Benedict's Test. However it is less popular as it less sensitive and requires that the reagents - Fehling's solutions A and B - be kept separate until the experiment is carried out.

Explanation:
When atoms forms ion, they either lose or gain electrons.
In an atom, we have three subatomic particles;
- Protons are the positively charged particles
- Electrons are the negatively charged particles
- Neutrons carry no charges.
A neutral atom has equal number of protons and electrons.
A positively charged atom has more protons than electrons which implies that they have lost electrons.
A negatively charge atom has more electrons than protons suggesting that they have gained more electrons.
If we are given Na, it will for Na⁺ when it loses the electron in its outermost shell. Hence the number of protons is now more and the atoms is positively charged.
