Answer: IONIC EQUATION.
Explanation:
A chemical equation is defined as the form by which a chemical reaction is represented mathematically. These are written in the form of symbols and chemical formulas of reactants and products which are taking part in the chemical reaction. A chemical equation can be written in two forms, these include:
--> MOLECULAR EQUATION: in this type of equations, the compounds are written and represented in a molecular form. This is sometimes referred to as a balanced equation.
--> IONIC EQUATION: This is a type of chemical equation in which the electrolytes in aqueous solution are expressed as dissociated ions. A typical illustrated example is seen in the reaction between AgNO3(aq) and NaCl(aq) :
Ag+(aq) + NO3-(aq) + Na+(aq) + Cl-(aq) → AgCl(s) + Na+(aq) + NO3-(aq)
The (aq) written in the above equation signifies they are in aqueous solution.
The volume that is needed to react completely with 0.100 mol of lead nitrate is 0.400 L. It is because 2 moles of HCl are required for every mole of lead nitrate.
2 x 0.100 mole Pb(NO₃) = 0.200 mole HCl
0.200 mol HCl = L x 0.500 M
Exponential growth can lead to decreasing the population size, which represents an example of a NEGATIVE feedback loop. This control mechanism (negative feedback) is common in nature.
Negative feedback is a homeostatic self-regulatory process by which the output of a given system is fed back in order to reduce its internal fluctuations.
In a negative feedback, an amplified output from the system (e.g., in this case, a sudden increased population size) leads to its self-inhibition.
This control mechanism (negative feedback loop) helps to maintain the homeostatic balance of the entire system in order to reach a set point.
