When is an isotope considered stable? (Select all that apply.)

Chemistry
1 answer:
GaryK [48]3 years ago
6 0

Explanation:

A stable isotope is one that does not emit radiation, or, if it does its half-life is too long to have been measured. It is believed that the stability of the nucleus of an isotope is determined by the ratio of neutrons to protons.

Hope this helps you out : D

In an experiment, the independent variable
Stolb23 [73]

Answer:

In an experiment the independent variable is special type of control which is control by the experimenter, and it effect the dependent variable.

Explanation:

In dependent variable:

The dependent variable is the variable which is controlled by the experimenter to check its effect on dependent variable.

Dependent variable:

It is variable which being measured in an experiment and which is directly depend upon independent variable.

The both variables are relate in term of  cause and effect. The independent variable is changed by experimenter and its effect produce in dependent variable is then measure.

For example:

To measure how sleep of student effect the test score. The time for a sleep is given by experimenter it is independent variable which may exceed or decreased. It depend upon experimenter choice but the effect on score is dependent variable which depend upon the time of sleep.

In lab an experiment was performed to determine the empirical formula of magnesium
Nat2105 [25]

Answer:

The correct option is

C) Trial 1 will have the same calculated empirical formula as trial 2.

Explanation:

The empirical formula is the formula of a chemical compound that states the simplest whole number ratio of each of the atoms included in the compound. It is obtained by dividing the mass of an element present in the compound by the element's molar mass to find the mole ratio of the elements. The obtained mole value for each element is then divided by the smallest number of moles obtained in the division.

By definition the composition and ratio of elements combined in a chemical compound is fixed, therefore trial 1 will have the same calculated empirical formula as trial 2.
