Answer:
An atom behaves electically neutral because it has an equal number of protons and electrons.
Explanation:
There are three sub-atomic particles: neutrons, electrons and protons. Neutrons have a neutral charge; electrons have a negative charge; and protons have a positive charge. In a regular atom, there is an equal amount of electrons and protons, making a neutral charge.
Answer:
127.15 g of ZnCl₂
Solution:
The balance chemical equation is as follow,
<span> Zn + 2 HCl </span>→ ZnCl₂ + H₂
According to equation,
65.38 g (1 mole) of Zn produced = 136.28 g (1 mole) of ZnCl₂
So,
61.0 g of Zn will produce = X g of ZnCl₂
Solving for X,
X = (61.0 g × 136.28 g) ÷ 65.38 g
X = 127.15 g of ZnCl₂
1st law states that energy cannot be created or destroyed in an isolated system hence the answer is the heat that flows into the system is transformed into work and change in internal energy....
