Sand is usually hot from the sun. It is hot because of the sun. if the sand were to be wet then it would take longer to change.
It is a statement of fact. explains how energy is produced, and describes the behavior of energy.
The soil with the highest water-holding capacity in the triangle must be a soil that has a very high percentage of clay soil.
The question is incomplete but I will try to help you the much I can. There are different kinds of soil such as;
- Sandy soil
- Loamy soil
- Clay soil
- Silt Soil
The water holding capacity of the various kinds of soil are different. The soil with the least water holding capacity is sandy soil while the soil with the greatest water holding capacity is clay soil.
Hence, the soil with the highest water-holding capacity in the triangle must be a soil that has a very high percentage of clay soil.

Answer:
Explanation:
Chemical equation:
FeCl₃ + NaOH → Fe(OH)₃ + NaCl
Balanced chemical equation:
FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl
Step 1:
FeCl₃ + NaOH → Fe(OH)₃ + NaCl
Fe = 1 Fe = 1
Cl = 3 Cl = 1
Na = 1 Na = 1
OH = 1 OH = 3
Step 2:
FeCl₃ + 3NaOH → Fe(OH)₃ + NaCl
Fe = 1 Fe = 1
Cl = 3 Cl = 1
Na = 3 Na = 1
OH = 3 OH = 3
Step 3:
FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl
Fe = 1 Fe = 1
Cl = 3 Cl = 3
Na = 3 Na = 3
OH = 3 OH = 3
Now we the equation is completely balanced and follow the law of conservation of mass because there are equal number of atoms of each elements are present on both side.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction
.
Type of reaction:
It is double displacement reaction.
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
Answer:
The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time. Reaction rates can vary dramatically.
