Answer : The correct option is, sour taste

Explanation :

Acid : It is a substance that has ability of donating proton or hydrogen ion or hydronium ion, H^+.

The properties of an acid are :

  • Acids are sour in taste.
  • The texture of an acid solution is sticky.
  • It changes the color of the litmus paper to red.
  • It react with a metal to give compound and hydrogen gas.
  • The pH of an acid is less than 7.

Base : It is a substance that has ability of donating hydroxide ion, OH^-.

The properties of an base are :

  • Base are bitter in taste.
  • The texture of an base solution is slippery.
  • It changes the color of the litmus paper to blue.
  • It does not react with a metal.
  • The pH of a base is more than 7.

As per question, the pH is 5 that means the solution is acidic in nature and follow the properties of an acid. So, the pH = 5 has the sour taste characteristic. While the other options are the properties of a base.

Hence, the correct option is, sour taste

A gas that effuses through a porous cylinder 1.87 times faster than chlorine gas. what is the molar mass and identity.
Rufina [12.5K]
From the Graham's law of effusion;
R1/R2 = √MM2/√MM1
Molar mass of chlorine gas is 71
Therefore;
1.87= √ 71 /√mm1
= 1.87² = 71/mm1 
mm1 = 71/1.87²
         = 71/3.4969
         = 20.3
Thus, the molar mass of the other gas is 20.3 , and i think the gas is neon

A solution is prepared by dissolving 0.23 mol of chloroacetic acid and 0.27 mol of sodium chloroacetate in water sufficient to y
Sergio [31]

Answer:

c. chloroacetate ion

Explanation:

The chloroacetic acid, ClCH₂CO₂H, is a weak acid with Ka = 1.36x10⁻³. When this weak acid is in solution with its conjugate base, ClCH₂CO₂⁻ (From sodium chloroacetate) a buffer is produced. The addition of a strong acid as the HCl produce the following reaction

HCl + ClCH₂CO₂⁻ → ClCH₂CO₂H + Cl⁻.

Where the acid reacts with the chloroacetate ion to produce more chloroacetic acid

That means, the HCl reacts with the chloroacetate ion present in the buffer solution

Right answer is:

<h3>c. chloroacetate ion</h3>

Which example describes how the water cycle carries on energy transfer? a flooding river depositing silt on a floodplain a warm
Irina18 [472]

Answer:

The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.

What alkene(s) would be produced from the dehydration of cyclopentanol? (enter "none" in the unused blanks.)
amm1812
Dehydration of Alcohols yield Alkenes. Depending upon the starting material (alcohols) different alkenes are being formed either by following saytzeff rule or Hoffman rule. In case of Cyclopentanol only one alkene is produced (i.e. Cyclopentene) as shown below.

a change will only occur one time. group of answer choices cyclic periodic unidirectional bidirectional
Irina18 [472]

A change will only occur one time in unidirectional.

Because

Cyclic : Cyclic compounds are chemical compounds having a basic non-linear structure. In other words, these are ring structures. One or more series of atoms in the compound is connected to form a ring structure.

Periodic : The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic number.

Unidirectional : compound is operating or moving in one direction only and it does not move in other direction.

Bidirectional : Capable of reacting or functioning in two, usually opposite, directions.

Thus, A change will only occur one time in unidirectional.
