When the concentrations of CO2 and H2CO3 are both horizontal lines then the rate of the forward reaction is the same as the rate of the reverse reaction.
<h3>What is rate of reaction?</h3>
The term rate of reaction refers to how fast or slow a reaction proceeds. Recall that the rate of reaction is measured from the rate of disappearance of reactants or the rate of appearance of products.
When the [CO2] and [H2CO3 ] are both horizontal lines, the rate of the forward reaction is the same as the rate of the reverse reaction.
Let us recall that the reaction is reversible hence addition of H2CO3 will increase the concentration of H2CO3, the reverse reaction would be favored.

Answer:
the answer is 4=Be 9 =F 16=S 17 = CL
Explanation:
atomic no 4 = beryllium (Be)
" " 9 = fluorine (F)
16 = sulfur (S)
17 = chlorine (CL)
Answer:
Independent variable: Type of pesticide
Dependent variable: Number of pests killed
Explanation:
A variable is a factor that can take on different values. In scientific researches, there are three main kinds of variables; Independent, dependent and control variables.
Independent variable: an independent variable is directly under the control of the experimenter. It is the variable that gives a value to the dependent value based on its manipulations. In this example, the type of pesticide used is dependent on the experimenter, either A or B
Dependent variable: This is a variable that is being studied. It is not directly under the manipulation of the experimenter but has its values from the changes of the independent variables. In this example, the number of pests killed is dependent on the changing of the type of pesticide used.
Control Variable: Control variables are extraneous variables that are not being directly studied but can affect the outcome of interest hence needs to be held constant.
