When 20. milliliters of 1.0 M HCL is diluted to a total volume of 60. milliliters, the concentration of the resulting solution is 1. 1.0 M 2. 0.50 M 3. 0.33 M 4. 0.25 M

Answers

Answer 1
Answer:

The concentration of the resulting solution is 0.33 M. The correct option is 3. 0.33 M

Dilution

From the question, we are to determine the concentration of the resulting solution

From the dilution law,

M₁V₁ = M₂V₂

Where M₁ is the initial concentration

V₁ is the initial volume

M₂ is the final concentration

V₂ is the final volume

From the given information

M₁ = 1.0 M

V₁ = 20 mL

M₂ = ?

V₂ = 60 mL

Then,

1 × 20 = M₂ × 60

20 = M₂ × 60

Therefore,

M₂ = 20 ÷ 60

M₂ = 0.33 M

Hence, the concentration of the resulting solution is 0.33 M. The correct option is 3. 0.33 M

Answer 2
Answer: C₁ * V₁ = C₂ * V₂

1.0 * 20 = C₂ * 60

20 = C₂ * 60

C₂ = 20 / 60

C₂ = 0.33 M

hope this helps!

In Indian cuisine, sometimes a papaya is added to make meat cook faster. Explain how this method works.

Answers

In Indian cuisine, sometimes a papaya is added to make meat cook faster. This is possible since papaya contains enzymes that functions as a meat tenderizer which is called the papain. Adding the papaya while cooking will excrete out the enzyme and do its function which is to tenderize the meat.

_____ is a halogen used in gaseous and liquid form for large scale disinfection of drinking water and sewage. A. Iodine B. Chlorine C. Bromine D. Fluorine E. Betadine

Answers

Answer:

Chlorine

Explanation:

Chlorine is a halogen that is a strong oxidizer (it takes electrons from nearby compounds).  In so doing, it kills bacteria, viruses, and other microorganisms.  The chlorine reacts with cell walls or other vital organic compounds (e.g., proteins)  to render them useless.  Chlorine is relatively inexpensive and generally easy to handle, but it is dangerous in gaseous form and highly alkaline in solution, so must be stored and handled properly.

In your own words, compare and contrast transverse and longitudinal waves. Be sure to include at least one similarity and one difference.

Answers

A transversewave is a wave is a wave in which the particles in the medium oscillate in a direction that is perpendicular or at 90 degrees to the direction in which the wave propagates. Light waves or electromagnetic waves are a good example of transverse waves. When an electromagnetic wave propagates, the medium in which it propagates vibrates in a direction perpendicular to the direction of travel.

A longitudinal wave is a wave in which the particles of the medium oscillate in a direction parallel to the direction in which the wave is travelling.  Sound waves are good examples of longitudinal waves. When sound propagates, the particles of the medium which it travels through will vibrate in the direction in which the wave is travelling.

                                         Similarities

  • Both transverse and longitudinal waves carry energy.
  • Both transverse and longitudinal waves obey the wave equation.
  • Both transverse and longitudinal waves show behavior such as refraction, reflection, absorption, diffraction, etc.

                                          Differences

The main difference is that for longitudinal waves, the particles in the medium will vibrate in the direction of the wave and that for transverse waves, the motion of the particles in the medium is in a direction perpendicular to the direction of propagation of the wave.

The sum of pH and pOH for any aqueous solution equals

Answers

pH is a notion that expresses the concentration of hydrogen in a solution while pOH expresses the concentration of hydroxide in a solution. The sum of pH and pOH in a solution is 14.

Answer: 14

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.

pH=-\log [H^+]

pOH=-\log[OH^-]

pH+pOH=14

Thus the sum of pH and pOH is 14.

What is the molarity of a solution of 14.0 g NH4Br in enough H20 to make 150 mL of solution?

Answers

Mass of solute = 14,0 g

Molar mass ( NH4Br ) = 14 + 1 . 4 + 80 = 98 g/mol-1

volume of the solution = 150 mL  = 0,15 L

Molarity of the solution = mol/L-1

M = (m)/(mm.V)

M = (14,0)/(98.0,15)

M = (14,0)/(14,7)

M = 0,952 mol/L ^(-1)
