Answer:
The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right.
Explanation:
Answer:
The answer is "The First choice".
Explanation:
The whole question can be found in the file attached.
The water vapor inside the air freezes thru the entrance of its nitrogen. This is because liquid nitrogen has a very low temperature and seems to be sufficiently cold to condensed and freeze the steam of water. At air pressure, it has a boiling temperature of -196°C. Freezing the skin producing freeze or cold burns can be associated with direct contact.
Let us assume that there is 1 mole of the solution present. The mass becomes:
Mass = fraction of carbon dioxide * Mr of carbon dioxide + fraction of water * Mr of water
Mass = 0.25*44 + 0.75*18
Mass = 24.5 grams
Now, we determine the volume of the solution using:
Volume = mass / density
Volume = 24.5/1 = 24.5 mL
The molarity of a solution is:
Molarity = moles / liter
Molarity = 0.25 / 0.0245
Molarity = 10.2 M
