b. there is no net change in the amount of substrates or products.
c. the reaction has stopped.
d. there are equivalent amounts of substrates and products.
Answer: b. there is no net change in the amount of substrates or products.
Explanation:
The reactions which do not go on completion and in which the reactant forms product and the products goes back to the reactants simultaneously are known as equilibrium reactions.
Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.
For a chemical equilibrium reaction, equilibrium state is achieved when the rate of forward reaction becomes equals to rate of the backward reaction.
Answer:
0.25
Explanation:
B. plants cannot grow on them.
C. the angle of their slope is less than 50 degrees.
D. the angle of their slope is greater than 40 degrees.
The right answer is D.
The slopes are differentiated by the following criteria:
*The inclination;
*The orientation;
*The shape of the slope.
The slope can be measured by degrees or percentages. In the mountains, it is necessary to measure the inclination of a slope by degrees and not by percentages of inclination.
to make the conversion it is necessary to consider that a slope of 45 ° equals a slope of 100%.
The name of the given chemical compound is called sodium sulfite.
Chemical is a term used to describe any substance that has a definite chemical composition.
The chemical name of is derived from the elements that make up the compound. Na stands for sodium, S stands for sulfur, and O stands for oxygen. The subscript 3 indicates that there are three oxygen atoms in the compound.
Therefore, the chemical is called sodium sulfite. It is an inorganic compound that is used in various chemical processes, as a preservative in the food industry, and in the production of paper.

B. Water molecules slow done until they begin to form stronger bonds together.
C. As water molecules cool, their shape changes from rounded to irregular, making them more likely to link to one another
D.Water molecules are squeezed together by high pressure until they begin to stick to one another.
The correct option is B.
When the temperature of water is reduced, the water cools down and the molecules of the water lose energy and move slowly. As the water is cooling down its volume expands. When the temperature of the water reaches zero degree Celsius, the molecules of the water stick together and form solid ice, thus turning from a liquid state to a solid state.
