Milk of magnesia is a base. what happens when you drink milk of magnesia for an upset stomach?

a)
it raises the ph of your stomach.
eliminate

b)
it lowers the ph of your stomach.

c)
it cleanses the stomach of harmful, painful bacteria.

d)
it coats the walls of your stomach with a protective layer.

A)  

It raises the pH of your stomach.

Explanation:

Milk of magnesia raises the pH of your stomach. This is because the pH of your acidic stomach is well below 7. Adding something with a high pH (a base) will raise the pH back to where it should be.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
