<span>"Depression in freezing point is used to prevent car fuel from freezing by adding anti-freeze." The antifreeze also causes an elevation in the boiling point, so it helped with a car overheating in the summer. In the USA, there was an antifreeze called Prestone that advertised itself as "winder-summer protection." Hope this helped! (:</span>
Answer:
Because of its permeability.
Explanation:
It is on quizlet. I don't think it is right though, I am sorry.
Dry air is a mixture of nitrogen, oxygen, carbon dioxide etc.
air is a mixture of gases 78% nitrogen an 21% oxygen and other components.
The Molar concentration of your analyte solution is 1.17 m
<h3>What is titration reaction?</h3>
- Titration is a chemical analysis procedure that determines the amount of a sample's ingredient by adding a precisely known amount of another substance to the measured sample, with which the desired constituent reacts in a specific, known proportion.
Make use of the titration formula.
The formula is molarity (M) of the acid x volume (V) of the acid = molarity (M) of the base x volume (V) of the base.
if the titrant and analyte have a 1:1 mole ratio. (Molarity is a measure of a solution's concentration represented as the number of moles of solute per litre of solution.)
26 x 1.8 = 40 x M
M = 26 x1.8 /40
M = 1.17
The Molar concentration of your analyte solution is 1.17 m

Answer:
The discovery of electron by j.j Thomson rejected the Dalton theory.
He stated that atom can be divided into its subatomic particles.
Explanation:
Dalton stated that atom is an indivisible particle. It can not be further subdivided.
The discovery of electron by j.j Thomson rejected the Dalton theory.
He stated that atom can be divided into its subatomic particles.
The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.
Symbol= e-
Mass= 9.10938356×10-31 Kg
It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.
He constructed the glass tube and create vacuum in it. He applied electric current between electrodes. He noticed that a ray of particles coming from cathode to wards positively charged anode. This ray was cathode ray.
Properties of cathode ray:
The ray is travel in straight line.
The cathode ray is independent of composition of cathode.
When electric field is applied cathode ray is deflected towards the positively charged plate.
Hence it was consist of negatively charged particles.
