Reactions can occur because of a precipitation reaction
<h3>Further explanation</h3>
Double-Replacement reactions, happens if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product
To predict whether this reaction can occur or not is one of them, the precipitation reaction. A precipitation reaction occurs if two ionic compounds which are dissolved reacted to produce one of the products of the ion compound does not dissolve. Formation of these precipitating compounds that cause reactions can occur
Chloride solution reacts with Sodium carbonate solution
CaCl₂(aq)+Na₂CO₃(aq)⇒CaCO₃(s)+NaCl(aq)
Because Calcium carbonate, CaCO₃ an insoluble solid , it will precipitates so that a reaction can occur
The greater the electronegativity difference, the more ionic the bond is. Bonds that are partly ionic are called polar covalent bonds. Nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
Answer:
Ecosystem
Explanation:
The answer is ecosystem because the ecosystem includes the community such as living things and the enviornment of nonliving things such as the sun!
Answer:
Photovoltaic cell or solar cells
Explanation:
Solar cells are cells that converts light energy from the sun into electrical energy for use in appliances. Light energy impinges on these cells, the photons of light causes electrons in the solar cells to move thereby resulting in the production of electricity in the cells.
