The answer should be letter C, since a compound is made of atoms of two or more elements, in a defined ratio, bonded together.
The skin feels a certain sensation from outside influences. The same thing that itches also detects hot, cold and sensations of other kinds. The technical term for it is stimulation of pruriceptors. When these pruriceptors are stimulated, the brain reacts with an appropriate response.
Answer:
A) CaCO₃
C) No precipitate
Explanation:
To answer these questions we need to consider the solubility rules.
<em>Identify the precipitate or lack thereof for the following:</em>
CaCl₂(aq) + K₂CO₃(aq) ⇒ CaCO₃(s) + 2 KCl(aq)
- Group II carbonates are insoluble. Thus, CaCO₃ is insoluble.
- Salts containing Group I cations are soluble. Thus, KCl is soluble.
FeCl₂(aq) + (NH₄)₂SO₄(aq) ⇒ FeSO₄(aq) + 2 NH₄Cl(aq)
- Most sulfates are soluble. Thus, FeSO₄ is soluble.
- Salts containing the ammonium ion are soluble. Thus, NH₄Cl is soluble.
