Answer:
A table was attached to the question
Explanation:
The step by step calculation is as shown
Answer:
An atom is composed of a positively-charged nucleus, with a cloud of negatively-charged electrons surrounding it, bound together by electrostatic force. ... Protons and neutrons are bound together to form a nucleus by the nuclear force.
Answer:
i) 24.305 u
iv) The number of protons determines an element's atomic number and is used to distinguish one element from another.
Answer: 0.123 M
Explanation:
According to the neutralization law:
where,
= molarity of 
solution = ?
= volume of solution = 15.00 ml
= molarity of 
solution = 0.100 M
= volume of solution = 18.44 ml
= valency of = 1
= valency of = 1
Therefore, the concentration of the unknown HBr solution is 0.123 M
