Answer:
Option B is correct.
The net ionic chemical reaction when Cu(NO₃)₂ reacts with water is
Cu²⁺(aq) + H₂O(l) ⇌ Cu(OH)¹⁺(aq) + H¹⁺(aq)
Explanation:
When ions dissolve in polar solvents (in water especially), then often attract ions of opposite signs.
Cu(NO₃)₂ dissolves into Cu²⁺ & NO₃⁻ and water contains H¹⁺ & OH⁻
The Cu²⁺ attracts the OH⁻ from water, thereby giving the Cu(OH)¹⁺ ion (with a net charge of +2-1 = +1) and the NO₃⁻ takes up the H⁺ ion.
the only explanation would be that it is on top of a hotspot I don't know if this helps at all
Answer:
<em>heterogeneous mixture is a mixture that is non-uniform and contains smaller component parts.</em>
Density is a physical property. It's measured and doesn't change the object chemically.
The state of matter for an object that has both definite volume and definite shape is solid.
