Answer:
1.054 x 10²⁴ molecules
Explanation:
In order to convert moles <em>of any given substance</em> into a number of molecules, we need to use <em>Avogadro's number</em>, which states the number of molecules -or atoms, in the case of elements- present in one mol:
- In one mol there are 6.023x10²³ molecules.
We now <u>convert 1.75 moles into molecules</u>:
- 1.75 mol * 6.023x10²³ molecules/mol = 1.05x10²⁴ molecules
Answer: it C
Explanation: Because is the only that makes sense and the only one that seems right
Answer:
Water and Salt are the products of simplest types of acid-base reactions.
Examples:
Base Acid Salt Water
NaOH + HCl → NaCl + H₂O
2 NaOH + H₂SO₄ → Na₂SO₄ + 2 H₂O
NaOH + CH₃CO₂H → CH₃COONa + H₂O
In all theses simple reactions the base (i.e. OH⁻) abstracts proton from the acid and forming a conjugate base with negative charge. Thus the negative charged conjugate base forms a salt with positively charged sodium ions.
