Answer: the filled in options are(from up to down): decreases; increases; decreases and increases
Explanation:
Ok, let us first full in the gap from the question;
''When a nonvolatile solute is added to a volatile solvent, the solution vapor pressure DECREASES, the boiling point INCREASES, the freezing point DECREASES, and the osmotic pressure across a semipermeable membrane INCREASES.
First, volatility is the tendency of a substance to vaporize.
WHAT IS A NON VOLATILE SOLUTE/SUBSTANCE ?:
A non volatile solute will not produce vapour at the boiling point of a particular solution. It is a solute that has low vapour pressure. This property, that is, a low vapour pressure will cause an increase in the boiling point. An example is glucose.
Non volatile solute, apart from increament in boiling point called boiling point elevation, it also decreases freezing point called freezing point depression.
Also, colligative properties such as osmotic pressure increases.
Answer:
The two unpopular actions made by the Umayyad's were that they moved the capitol and they made it so that the title of caliph could only be passed down from father to son, that it had to be passed along only inside the clan.
Which is the majority group of Muslims? - Sunni.
What is the minority? - Shi'ite.
The Sunni believe all Muslim could be caliph.
The Shi'ite believe that only members of Muhammad's family could be caliph.
Explanation:
the answer should be: The study's construct validity
A study's construct validity refers to the degree to which the experiments made in the study actually measures what it intended to measure. This can be seen on the study's standard of measurement and the correlation between variables used in the measurement and the actual phenomenon.
After hearing the claimed made by the teacher, Clarissa's immediately question whether the act of bullying can be measured.
She brought up an important point. The teacher never really specify what act considered as 'bullying'. Depending on people's perception, some consider a slight discomfort from social interaction might be considered as bullying, while other people might have the threshold. Because of this, she can say that the study's construct validity is questionable.
Answer:
Public smoking bans appear to significantly reduce the risk of heart attacks, particularly among younger individuals and nonsmokers, according to a new study. Researchers find that smoking bans can reduce the number of heart attacks by as much as 26 percent per year.
