There in an increase in reactivity because the nonmetals want to hold on to their electrons.

<h3>Reactivity</h3>

With less electronegativity, there is also less ionization energy. For metals, it is easier to lose the electrons, hence the metal becomes more reactive because it uses less energy.

For nonmetals, they are gain electrons and not lose them. Thus, an increase in electronegativity and ionization energy means an increase in reactivity because the nonmetals want to hold on to their electrons.

A data analyst is working with a data frame named customers. It has separate columns for area code (area_code) and phone number

VARVARA [1.3K]

The code chunk that lets the analyst create the phone_number column is: unite(customers, "phone_number", area_code, phone_num, sep="-"

<h3>What is a data frame?</h3>

A data frame refers to a two-dimensional array-like structure or table that is made up of rows and columns, which is typically used for storing data in R Studio using the R programming language.

In Computer programming, a data frame is a list of vectors that are all equal in length, and each column consist of values of one variable while each row consist of a set of values from each column.

<h3>The executable code in R Studio.</h3>

In this scenario, the code chunk that would be used to create a data frame that combines the two columns into a single column (phone_number) is:

unite(customers, "phone_number", area_code, phone_num, sep="-"

Anastaziya [24]

The expression (PE products) - (PE reactants) represents the heat of reaction for a chemical change in terms of PE (potential energy).

<h3>What is potential energy?</h3>

Potential energy is any type of energy stored to perform physical work in a given period of time.

Conversely, kinetic energy is motion (movement) energy used when performing physical work.

In conclusion, the expression (PE products) - (PE reactants) represents the heat of reaction for a chemical change in terms of PE (potential energy).

Based on the information given, it should be noted that the slope cannot be interpreted as the equation makes no sense for the model.

<h3>Interpretation of the slope.</h3>

From the information given, the explanatory variable x was the year that the observations were taken.

In this case, the values are the integer number between 1975 and 1986. The y-intercept of the equation makes no sense for the prediction as it's not in the range of the explanatory data.
