Baking soda (sodium bicarbonate) is often used to neutralize spills of acids on the benchtop of the laboratory. What mass of sodium bicarbonate would be needed to neutralize a spill consisting of 25.2 mL of 6.01 M hydrochloric acid solution?

Answer : The mass of needed is, 12.7 grams.

Explanation :

First we have to calculate the moles of HCl.

Now we have to calculate the moles of

The balanced neutralization reaction will be:

From the balanced chemical reaction we conclude that,

As, 1 mole of HCl neutralizes by 1 mole of

So, 0.151 mole of HCl neutralizes by 0.151 mole of

Now we have to calculate the mass of

Molar mass of = 84 g/mole

Therefore, the mass of needed is, 12.7 grams.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

the correct answer is:

a. formation of precipitation
