A researcher investigated the relationship between alcohol intake and reaction time using a driving simulation task. Participants drank either one ounce or three ounces of alcohol. Their reaction time was measured in terms of the speed with which they braked on seeing a red light during the simulated driving task. In this case, the dependent variable in the experiment is the

Reaction time

Explanation:

Dependent variables are the actual variables being measured during the course of an experiment whose values depends on the independent variables. In other words, dependent variables are those whose values varies as a result of change in the values of independent variables during an experiment.

In this case, the independent variable is the amount of alcohol intake while the dependent variable is the reaction time. As the amount of alcohol taken varies, the reaction time will also vary as the case may be.

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
