Answer:
The atomic mass number is the number of protons and neutrons in an atom.
Answer:
The answer to your question is letter C.
Explanation:
Reaction
Potassium hydroxide = KOH
Barium chloride = BaCl₂
Potassium chloride = KCl
Barium hydroxide = Ba(OH)₂
KOH + BaCl₂ ⇒ KCl + Ba(OH)₂
Reactant Elements Products
1 K 1
1 Ba 1
2 Cl 1
1 H 2
1 O 2
The reaction is unbalanced
2KOH + BaCl₂ ⇒ 2KCl + Ba(OH)₂
Reactant Elements Products
2 K 2
1 Ba 1
2 Cl 2
2 H 2
2 O 2
Now, the reaction is balanced
Answer:
Induction
Explanation:
When a body is brought in contact with another, electrons are rearranged by contact.
When a body is rubbed against one another, charging by friction occurs.
The process whereby electrons are rearranged without direct contact with one another is called induction.
By induction electrons can get charged without them having to be in contact with one another.
- When a charged body is brought to the vicinity of the electrons, either an attraction or repulsion force is set up.
- Similar charges causes repulsion
- If a negatively charged body is brought near the electrons, there would be heavy repulsion and the electrons would be forced to rearranged.
- This effect is product as a result of a force field.
With an atomic number of 55, that means there are 55 protons. Because electrons do not count towards atomic weight, the element would have 150-55 neutrons. So, 95 neutrons.
