Answer:
2 HCl + Ba(OH)₂ ⇒ BaCl₂ + 2 H₂O
Explanation:
In a complete neutralization reaction, an acid reacts with a base to form neutral salt and water. To form barium chloride, hydrochloric acid (acid) reacts with barium hydroxide (base). The balanced chemical equation is:
2 HCl + Ba(OH)₂ ⇒ BaCl₂ + 2 H₂O
It is not correct to say " a molecule of salt " because salt is a compound.
Explanation:
- As we know a molecular bond is present in each molecule.
- Salt (NaCl) is considered as a compound because it is made up of two types of elements that are sodium as well as chlorine.
- On the other hand it is not considered as a molecule as it is not holding an ionic bond.
- As a result we can name it as an ionic compound. Hence it is not considered as a molecule of salt.
Answer:
Climate change and an increase in unpredictable and extreme weather is a growing challenge. Long periods of drought affect clean water supplies while flooding can pollute clean water sources and cause outbreaks of disease.
Answer: weigh is m = n × M = 2.87 mol × 58.44 g/mol
Explanation: mass = amount of substance × molar mass
M((NaCl) = 22.99 +35.45
