What is the best way to compare a concentrated solution to a dilute solution, given the same volume of solution?The concentrated solution has less solute than the dilute solution.
a) The concentrated solution has the same amount of solute as the dilute solution.
b) The concentrated solution has more solute than the dilute solution.
c) The concentrated solution has a different amount of solute than the dilute solution.
d) The concentrated solution has the same amount of solute as the dilute solution.

Answers

Answer 1

Answer: The correct answer is B. Given a same volume of a solution, the concentrated solution has more solute than the dilute solution. For instance, we are given two NaOH solutions having a volume of 1L one has a concentration of 1M and the other is 2M. The latter has more solute since it has 2 moles of NaOH while the other only has 1 mole.

Answer 2

Answer:

Answer: b) The concentrated solution has more solute than the dilute solution.

Explanation:-

Binary Solution is a homogeneous mixture of two components called as solute and solvent. Solute is the component which is present in smaller proportion and is solid for solid in liquid solution and solvent is the component which is present in larger proportion and is liquid for solid in liquid solution.

Concentrated solution is one in which there is more amount of solid.

Dilute solution is one in which there is more amount of liquid.

Which of these 1 M solutions will have the highest pH?(1) NaOH (3) HCl(2) CH3OH (4) NaCl

Answers

Answer:

(1) NaOH

Explanation:

NaOH, sodium hydroxide is a base. HCl, hydrochloric acid is an acid. CH3OH, methanol is an alcohol. NaCl, sodium chloride is salt.

pH below 7.0 is acidic, pH above 7.0 is basic, and pH at 7.0 is neutral.

Since NaOH is the only base in among the given compounds, its pH will above 7.0. Therefore, NaOH will have the highest pH.

Final answer:

NaOH solution will have the highest pH.

Explanation:

The solution with the highest pH would be the one that is basic, as basic solutions have higher pH values. Among the given options, NaOH is a strong base and dissociates completely in water to produce OH- ions, which makes the solution highly basic.

The fermentation of C6H12O6 will produce CO2 and 1. C3H5(OH)3 2. C2H5OH 3. Ca(OH)2 4. Cr(OH)3

Answers

Answer is "2 - C₂H₅OH".

Fermentation is a process which is used to produce energy from sugars (glucose, sucrose and fructose) in the absence of oxygen.

Fermentation with the glucose releases energy by producing carbon dioxide (CO₂) and ethanol (C₂H₅OH) as its byproducts.
The reaction is
C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂ + energy

What is true about an ocean current that is moving toward the equatorA. Warm
B. Fast
C. Cold
D. Slow

Answers

Ocean current that is moving toward the equator is cold. The windblown surface currents distribute heat all over the globe through moving the water which is warm away from the equator and the cool water will replace which is from the north and south poles. An example of this is the Gulf Stream which moves warm water towards the Great Britain and Europe.

HNO3 increases the concentration of ____ when added to water

Answers

Since HNO3 is a strong acid, it would dissociate completely forming ions of H+ and NO3-. The ionization or dissociation of HNO3 will increase the concentration and or amount of H+ within the water, resulting in the pH or measure of H+ to decrease, indicating that the solution is tending to become acidic.
