The correlation coefficient is a number between zero and 1 and the answer is <u>false</u>
And that is because the correlation coefficient is a number between -1 and one. A positive correlation coefficient means that two variables are positively correlated or move in the same direction. Plus one means perfect like full correlation, zero means there is no correlation whatsoever.
And a negative correlation means that as one variable moves in a positive direction, the other moves in a negative direction, so that is negative correlation, And the correlation of -1 means perfect negative correlation.
<h3>What Is the Correlation Coefficient?</h3>
The correlation coefficient is a statistical measure of the strength of the relationship between the relative movements of two variables. The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement.
A correlation of -1.0 shows a perfect negative correlation, while a correlation of 1.0 shows a perfect positive correlation. A correlation of 0.0 shows no linear relationship between the movement of the two variables.

Answer:
32 grams
Explanation:
To find the molar mass of oxygen gas, you need to take a look at it's molecular formula. Oxygen is O2, and since each oxygen molecule has a molar mass of 16, 2 of them together have a molar mass of 32 grams. Hope this helps!

Answer is: adding NaCl will lower the freezing point of a solution. A solution (in this example solution of sodium chloride) freezes at a lower temperature than does the pure solvent (deionized water). The higher the solute concentration (sodium chloride), freezing point depression of the solution will be greater.
Option(A) is the correct answer.
The alkane with six carbons is called hexane.
<h3>What are the potential hazards of hexane?</h3>
Hexane is used as a special-purpose solvent, a cleaning agent, and to extract edible oils from seeds and vegetables. Humans who are acutely (short-term) inhaled high quantities of hexane have moderate central nervous system (CNS) symptoms such giddiness, nausea, headache, and dizziness. Humans who are exposed to hexane in the air <u>over an extended period of time</u> may develop polyneuropathy, which manifests as numbness in the extremities, muscle weakness, impaired vision, headaches, and tiredness. Rats have also displayed neurotoxic consequences. Hexane's potential to cause cancer in both humans and animals is unknown. Hexane has been categorized by the EPA as Group D, not classifiable as a human carcinogen.
