Answer:  Depression in Freezing Point

Explanation:  When salt is kept on the icy roads, it will form a liquid layer over it thereby lowering the freezing point below the ice. Thus when this salty liquid comes into the contact with the other ice present on the road making the other ice get melt.

This keeps on decreasing the olume of the ice on the road.

Thus it is always advised to put rock salts on the roads during a snowstorm.

The answer could honestly be as simple as "Putting rock salt on the roads during a snowstorm is an example of a chemical reaction" but due to lack of context I'm not sure, hope this helps anyways!

Pls help question 2 ill attach a picture​
Finger [1]

Answer:

X 154

Check solution in explanation

Explanation:

Average atomic mass = ( mass 1× abudance) + ( mass 2× abudance)+ ( mass 3× abudance) / 100

(149×13.8)+(152×44.9) +(154×41.3)/100

2056.2 + 6824.8 + 6360.2/100

=152.412

(b) what is the ph of a solution containing 0.03m benzoic acid (pka 3.19) and 0.02m nabenzoate?
Makovka662 [10]
Answer is: pH of solution is 3,02.
c(benzoic acid) = 0,03 mol/dm³.
c(sodium benzoate) = 0,02 mol/dm³.
pKa(benzoik acid) = 3,19.
pH = ?
Henderson–Hasselbalch equation for buffers: pH = pKa + log(cs/ck)
pH = 3,19 + log(0,02/0,03)
pH = 3,19 - 0,176 
pH = 3,02.
cs - concentration of acid.

An unknown substance is measured. It has a mass of 0.221 g and a volume of 2.25 mL. What is its density?
Alex Ar [27]

Answer:

d ≈ 0.098 g/mL

Explanation:

The density of a substance can be found by dividing the mass by the volume.

d=m/v

The mass of the substance is 0.221 grams and the volume is 2.25 milliliters.

m= 0.221 g

v= 2.25 mL

Substitute the values into the formula.

d= 0.221 g / 2.25 mL

Divide

d= 0.098222222 g/mL

Let’s round to the nearest thousandth. The 2 in the ten thousandths tells us to keep the 8 in the thousandth place.

d ≈ 0.098 g/mL

The density of the substance is about 0.098 grams per milliliter.
