Answer: The moles of HCl are 0.0244
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute = ?
= volume of solution in ml
Now put all the given values in the formula of molality, we get
Therefore, the moles of HCl are 0.0244
Answer:
The answer to your question is below
Explanation:
I just write the formulas of the reactants and products and balanced the reactions.
a)
3H₂(g) + N₂(g) ⇒ 2NH₃
b)
2K + 2H₂O ⇒ 2KOH + H₂ (g)
c)
2Al(s) + Fe₂O₃ ⇒ Al₂O₃ + 2Fe
d)
Fe₂O₃ + 2Al ⇒ Al₂O₃ + 2Fe
e)
Ba(OH)₂ + 2HBr ⇒ BaBr₂ + 2H₂O
f)
CaCO₃ + Δ ⇒ CaO + CO₂
The indivisibility of an atom was proved wrong and no longer accepted today.
<h3>What is an atom?</h3>
An atom is a particle of matter that uniquely defines a chemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons.
The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons.
Hence, an atom is the smallest particle that takes part in chemical reactions.
