Gastric acid plays a key role in the digestion of proteins by activating digestive enzymes and often has a pH value in the range

of 1.5 to 3.5. If the pH of the acid at a given time is found to be 1.25, calculate the molarity of the gastric acid juice.

If the pH of the acid at a given time is found to be 1.25, then the molarity  of the gastric acid juice is 0.056M.

<h3>What is pH?</h3>

pH is define as the negative logarithm of the concentration of H⁺ ions present in any solution and it will be represented as:

pH = -log[H⁺]

Concentration will be present in the form of molarity and pH value for gastric acid is given 1.25 means it is strong acid as it completely dissociates into their ions.

Required equation for calculation will be:

[H⁺] = 10^{-pH}

[H⁺] = 10^{-1.25}

[H⁺] = 0.056 M

Hence molarity of the gastric acid juice is 0.056M.

Which formula correctly represents antinomy trichloride?<br> SnS2<br> SnCl3<br> SbCl2<br> SbCl3
max2010maxim [7]

Answer:

SbcI3

Explanation:

The symbol of antimony is 'Sb'.

The symbol of chlorine is 'Cl'

First write down the symbol of the first element.

Use the prefix to determine the atoms of first element. If there is no prefix on element then there is only 1 atom.

Now write down the symbol of the second element.

Use the prefix to determine the atoms of second element.

Use prefix as 'mono' for '1', 'di' for '2', 'tri' for '3' and so on.

Explain the different principles that allow roller coasters to rip and roar around the tracks. In your response, include how ene
Jlenok [28]

Answer:

In the roller coasters the potential energy that is given is the gravitational potential energy, which this energy increases its value as the object moves away from the earth, that is to say, the more height the roller coaster acquires the more gravitational potential energy it will have, and Said train where people usually get on the roller coaster will descend or descend with greater acceleration.

This gravitational potential energy once the mountain begins to descend or descend is converted into kinetic energy

Explanation:

This that we wrote above is considering that the roller coaster does not have curved routes but rectilinear, in the case that it had curved routes, a force would be added in addition to those written that is the centripetal force, it is the same force that appears in the centrifuges or dryers of clothes or the same washing machine. This force, the centripetal force is the force that draws a moving object, in a curvilinear path, towards the center of the curvature.
