Why do none of the substrates given as choices for this experiment include any with meta-directing group?
Because none of the substrates are deactivating. Both of the substrates, p-xylene and ethylbenzene, have slightly activating groups which direct ortho or para.
Functional group is a certain group of atoms that?
Functional groups are the atoms or groups of atoms which largely defines the chemical properties of any organic compound. Eg: ch3-oh are alcohols
What is the scientific term for the things you make sure don't change during a experiment?
I assume the term for something that is not changed during an experiment is called, the control. Any changes observed in the experiment, can be compare to the control, which is still be in the original form before the experiment began.
What group is ammonium in?
The chemical formula for Ammonium is NH4+, it is not an element but a compound. Therefore it does not belong to any groups. Nitrogen(N) is in group 5 and Hydrogen(H) is in group 1.
What is the one factor that is different between the control group and the experimental group?
By definition, the control group is what the experimental group is measured against. For example, if one is doing an experiment to measure the effect of a drug on blood pressure, the experimental group would receive the drug and the control group would receive the placebo, or blank. The blood pressure of both groups would be measured after ingestion of either the drug or placebo and any differences in blood pressure we would attribute to the effect of the drug. Care must be taken, however, that the two groups are as identical as possible and that all procedures are carried out identically. Furthermore, to eliminate even more bias, both the researchers and the experimental subjects would not know whether they were receiving drug or placebo (a double-blind study).
In an experiment there are two groups. Which group is not changed in any way?
the control.constantif you make no changes, then its not called an experiment...The control is variable
In this experiment what is the control?
True
Why do you need a control group and a experimental group?
A control group is not provided any treatment, while the experimental group is the one to which a treatment is applied. The control and experimental groups are chosen to be as similar as possible, so that the observed effect (if any) can be attributed to the variable: what only the experimental group consumes, uses, or participates in.
What are science controls?
In an experiment, the control is the group to which nothing is done. It serves as a baseline to measure any changes that might occur to the group or groups that to which external variable is applied.
What is any part of an experiment that can change?
what can be change an experiment like what is the word
What groups can you be in for Answers.com?
you can not be in a group , there is not any groups.
Randomization in an experiment ensures that any difference in the responses of the experiment groups is due to the treatment?
true
What is an controlled experiment?
A controlled experiment can be used to test almost anything. In a controlled experiment, the scientist (or experimenter) use a control group and an experimental group. The control group has nothing changed about it, and experiment group is changed based on the variable of the experiment. One of the most common uses of controlled experiments is the testing of new medications. In a medical study, a pharmaceutical company usually brings in a group of 100 people. Those people people are randomly assigned to two groups of 50. The experiment group is given the medication being tested, and the control group is given a placebo (a sugar pill). After several weeks, the experimenter can then see the side-effects of the medication, by comparing the differences between the experiment and control groups.
What is a experimental group?
In a scientific experiment it is common to split your sample into (at least) two groups. Say you were to study the effect of a new drug on a specific condition, you would have a sample (a group of people with the condition in question e.g. breast cancer), and you would treat all members of the sample the same, with the exception that one group is give the actual drug, and the other group is given a "fake" pill. This fake pill is also called a placebo. The group that is given the real drug is called the experimental group, and the group that is give the placebo is called the control group. This setup attempts to ensure that any effect that is observed is caused by the drug (the experimental condition).
What is any condition in an experiment that can change?
Variable
What is the role of a control group in any experiment?
To compare data
In a experiment a is any factor that can change or be changed?
variable
