Density = 0.82 gm/L


Explanation:
Caco3= 40+12+16x2
= 100gm

CO2= 12+16x2
=44 gm

44/100 x 435

= 191.4gm


The mass of CO2 = 191.4gm
Volume of co2= 225L


Density= mass/volume = 191.4gm/225 L


= 0.85 gm/L

When molten candle wax solidifies is that a chemical reaction or not?l
andrey2020 [161]

Yes, when molten candle wax solidifies it is a chemical reaction

<u>Explanation:</u>

Basically Wax is crystalline so once the candle light melts it freezes taking back the solid state to the room temperature.

When the room temperature is below the freezing point, the liquid candle wax, turns into solid state again, therefore this process is called solidification. The process of freezing or solidification is a process when an object turns liquid and freezes back to solid state.

Indeed, Yes, when molten candle wax solidifies it is a chemical reaction

Fractional distillation of a mass mixture of 10 g water and 10 g perchloric acid would yield a distillate with what composition
jek_recluse [69]

Azeotrope is a mixture of two or more liquids whose proportions cannot be changed by simple distillation.

Explanation:

Nitic acid and water is an example of azeotrope. The composition of 68% of nitric acid and 32% of water by mass in a boiling point of 393.5k.

The composition of perchloric acid (71.6%) and water boils at 203°c. Pure iron solution weights about 10g is placed in a beaker, hydrochloric acid and nitric acid mixtures are added and heated to dissolve. Add perchloric acid until it evaporate and produces white smoke.cool it down add water and dissolve the salt.

Calculate the ph of this solution. round to the nearest hundredth. poh = 3.45 ph =
maks197457 [2]

The potential of hydrogen pH of the solution with the given value of pOH to the nearest hundredth is 10.55.

What is pH of solution?

The pH of a solution is defined as the logarithm of the reciprocal of the hydrogen ion concentration  [H+] of the given solution.

It is expressed as;

pH = -log[ H⁺ ]

Also,

pH + pOH = 14

Given that;

  • pOH = 3.45
  • pH = ?

We simply substitute our values into the expression above.

pH + pOH = 14

pH + 3.45 = 14

pH = 14 - 3.45

pH = 10.55

Therefore, the potential of hydrogen pH of the solution with the given value of pOH to the nearest hundredth is 10.55.
