The shape that is formed by the free surface, which is called a hyperboloid, or "Gabriel's Horn". The core of a vortex in air is sometimes visible because a plume of water vapor that is caused by condensation in the low pressure and low temperature of the core. An example of this is the sprout of a tornado. Vortices form in stirred fluids and could be observed in phenomena such as smoke rings, whirlpools in the wake of a boat, or the winds surrounding a tornado or dust devil.
The neutralization reaction is expressed as:
2KOH + H2SO4 = K2SO4 + 2H2O
We are given the volume and the concentration of the KOH that is used in the reaction. We use this and the relations from the reaction to determine the concentration of the acid.
0.150 mol KOH / L ( .025 L ) ( 1 mol H2SO4 / 2 mol KOH ) = 0.00188 mol H2SO4
Concentration of acid = 0.00188 mol / .015 = 0.125 M of sulfuric acid
The question is: 10 g of carbonic acid H2CO3 are dissolved in 150 g of water. Determine the% m / m concentration of that solution?
Answer: The% m / m concentration of that solution is 6.66%.
Explanation:
Given: Mass of solute = 10 g
Mass of solvent = 150 g
Formula used to calculate the %m/m is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that the% m / m concentration of that solution is 6.66%.
Your answer is c i am pretty sure
