Answer;
-Macroscopic properties remain constant
-Concentrations remain constant
-No change to copper solution seen;
-Rate of reverse/backwards reaction = rate of forward reaction;
Explanation;
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.
-It is a a condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs. A reversible chemical reaction is one in which the products, as soon as they are formed, react to produce the original reactants.
0.07cm³
Explanation:
Given parameters:
Density of the body = 350g/cm³
Mass of the body = 25g
Unknown:
Volume of the body = ?
Solution:
Density is the amount of substance contained in a volume of body. It is expressed as:
Density = 
Since the unknown is volume, we make it the subject of the expression;
Volume = 
Volume =
= 0.07cm³

Answer:
Explanation:
solar cell - converts sunlight into electricity
geothermal energy - heat produced within the Earth
wave energy - turns turbines along coastlines
hydroelectricity - water falling through dams turns turbines, generates electricity
The five main branches of chemistry are organic chemistry, inorganic chemistry, analytical chemistry, physical chemistry and biochemistry. Chemistry can be further divided into many sub-branches that may fall under more than one of the main branches.
