The simple formula is C = n/V
n = mols
C = Concentration or Molarity
V = Volume in Liters.
n = 2
V = 4
C = 2 / 4
C = 0.5 mol/Litre
Answer:
HCl (aq) + KOH (aq) --------> KCl (aq) + H2O (l) [balanced molecular equation]
Explanation:
Balanced molecular equation has all the components of reaction written as "molecules" thus the name molecular (the other equations break appropriate components into ions, those are total ionic or net ionic equation)
We know hydrochloride acid solution is written as HCl (aq) and potassium hydroxide solution is written as KOH (aq). We know from our knowledge that when acids react with bases they make salt and water, so now we react!
HCl (aq) + KOH (aq) --------> KCl (aq) + H2O (l) [balanced molecular equation]
the any four ways in which a chemical equipment can be more informative are 1 colour change2 change of temperature 3 evolution of gas 4 production of n odar
Explanation:
if the answer is correct mark me as brain list
1. CaS
2. Nitrogen forms an anion with a -3 charge.
3. S
4. Ca2N3
5. Mg3N2. Magnesium nitride
6. CaO. So 1,1
7. 2- O2- (2- is super scripted). It is also an anion, which is a negatively charged ion.
8. That would be aluminum iodide AlI3, also called aluminum triiodide.
9. LiCI
These should be correct. Hope I helped. ^~^
