You drink out of a drinking fountain for a full minute. How many moles of water did you just drink? (You need to know how much w
Mila [183]

First of all water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms. So lets say x = 3m, m=1, and x=3, because 3 x 1 = 3 = x, and r = radius of drinking fountain's water dispense, and AOW = amount of water produced in a minute, and y = (x*(r*(AOW/r))... So Y = a, and a = answer... Meaning your answer is (y = (x*(r*(AOW/r)) )!

What is the molarity of a HNO3 solution prepared by adding 290.7 mL of water to 350.0 mL of 12.3 M HNO3?
Lisa [10]

Answer:

6.72M of HNO3

Explanation:

In the problem you are diluting the original HNO3 solution by the addition of some water. The final volume is:

290.7mL + 350.0mL = 640.7mL

And you are diluting the solution:

640.7mL / 350.0mL = 1.8306 times

As the original concentration was 12.3M, the final concentration will be:

12.3M / 1.8306 =

Brownian motion is not observed in a mixture that includes two phases. Which best identifies the mixture? a colloid a suspension
12345 [234]

Answer is: a suspension.

Suspension is a heterogeneous mixture (solute particles do not dissolve), that contains solid particles (for example nickel sulfide or NiS) sufficiently large for sedimentation.  

The internal phase (solid nickel sulfide) is dispersed throughout the external phase (water).

Another example of a suspension is sand in water.
