A standard solution is a solution (in this case sodium hydroxide) whose concentration (molarity) is known very precisely. <span>The molarity of the sodium hydroxide solution cannot be determined accurately because s</span>olid sodium hydroxide is highly hygroscopic (absorbs water from the air) and cannot be accurately weighed. Sodium hydroxide form sodium carbonate because it absorbs carbon
dioxide from the air.
THe name of this alkane is <span>1-ethyl,3-methylcyclohexane</span>
Answer:
then it only gotta be 2 other options .
Explanation:
<h3>
Answer:</h3>
0.95 atm
<h3>
Explanation:</h3>
We are given;
Initial pressure, P1 = 1.0 atm
Initial temperature, T1 =298 K (25°C + 273)
Initial volume, V1 = 0.985 L
Final temperature, T2 = 295 K (22°C + 273)
Final volume, V2 = 1.030 L
We are required to find final air pressure;
Using the combined gas law;

To get, P2 ;



= 0.95 atm
Therefore, the air pressure at the top of the mountain is 0.95 atm
The independent variable is what you are testing in the experiment - it sounds like the independent variable in this experiment is the amount/concentration of nitrogen
