Which compound has the highest boiling point group of answer choices?
NaCl
Which compound has the lowest boiling point group of answer choices?
1 Expert Answer CH4 has only dispersion forces while all the others have dispersion PLUS either dipole-dipole (HCl, H2S, NH3), and/or hydrogen bonding (NH3). So, CH4 will have the lowest boiling point.
What has the lowest boiling point?
helium
How do you determine lowest boiling point?
3 Trends That Affect Boiling Points
- The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces.
- Boiling points increase as the number of carbons is increased.
- Branching decreases boiling point.
How do you determine boiling point?
Boiling Point Formula – Boiling Point Elevation Formula & Solved Examples
- ΔTb=1000×Kb×wM×W where, ” is weight of the solute, ” is the molar mass of the solute and ‘W’ is the weight of the solvent in grams.
- ΔTb=1000×Kb×wM×W.
- 1.1=1000×2.53×10M×200.
How pressure affects boiling point?
Atmospheric Pressure and Boiling The pressure of gas above a liquid affects the boiling point. In an open system this is called atmospheric pressure. The greater the pressure, the more energy required for liquids to boil, and the higher the boiling point.
What is freezing point and boiling point?
About Transcript. Boiling point elevation is the raising of a solvent’s boiling point due to the addition of a solute. Similarly, freezing point depression is the lowering of a solvent’s freezing point due to the addition of a solute. In fact, as the boiling point of a solvent increases, its freezing point decreases.
What temperature does water boil at 20 psi?
| Absolute pressure | Water boiling point | |
|---|---|---|
| [bara] [1×105*Pa] | [psia] | [°C] |
| 1.310 | 19.0 | 107 |
| 1.379 | 20.0 | 109 |
| 1.517 | 22.0 | 112 |
Can water boil at 20 degrees?
Yes, You Can Boil Water at Room Temperature.
What antifreeze has the highest boiling point?
Evans waterless coolants have a boiling point of over 375°F, far above the operating temperature of the engine. The high boiling point ensures that the coolant remains liquid at all times, enabling consistently effective cooling.
What temperature does 50/50 antifreeze boil?
Pure water, as you may know, has a boiling point of 212°F (100°C) and a freezing point of 32°F (0°C). However, when you create a 50/50 mixture using water and ethylene glycol, the boiling point rises to 223°F (106°C) and the freezing point lowers to -35°F (-37°C).
Should I use 50/50 coolant or concentrate?
Most manufacturers recommend a 50/50 mix of antifreeze concentrate to water. Mixtures with too much water may not provide adequate boil over or freeze protection. Mixtures with too much antifreeze concentrate may actually cause over heating.
What happens if you mix water with 50 50 antifreeze?
When mixed in equal parts with water (50/50), antifreeze lowers the freezing point to -35 degrees F and raises the boiling temperature to 223 degrees F. Antifreeze also includes corrosion inhibitors to protect the engine and cooling system against rust and corrosion.
What’s the difference between 50/50 coolant and concentrate?
So basically, buying the 50/50 mixture means you’re spending way too much money on water. The Ready to Use formula can be added to your coolant reservoir directly from the bottle, whilst the concentrated alternative will need to be mixed with water prior to use.
What color is 50 50 antifreeze?
Compatible for use in all automobiles and light-duty trucks. Yellow color will not change the current antifreeze color when used for topping-off. Provides 150,000 miles or 5 years of maximum protection when a complete cooling system flush and fill is performed. Features a phosphate-free and silicate-free formula.
What can I mix with coolant concentrate?
How to Dilute Antifreeze
- Pour half of the gallon-container of antifreeze into an empty, clean one-gallon container.
- Fill each of the gallon containers, which are both already half-filled with antifreeze, with distilled water. Each container should now contain a 50/50 mixture of water and antifreeze.
What color is Prestone 50/50 antifreeze?
yellow
What color is universal antifreeze?
green
Can I use Prestone 50/50 in my Honda?
In OAT antifreeze the silicate has been replaced with phosphates. So any OAT antifreeze will work in a Honda, but don’t use silicate antifreeze in any Japanese coolant system, Honda or otherwise. Prestone Regular or 50/50 is a silicate free OAT antifreeze. It uses phosphates to replace the silicates.
What color is Honda Type 2 antifreeze?
Re: Honda Type 2 Coolant the blue stuff (silvercivicsir) which the green coolant contains.
What coolant does Honda use?
You can use either blue or green antifreeze in your Honda without impacting the antifreeze’s performance; the color difference is simply a result of the different dyes used in making the product. If you have previously used green antifreeze, you can still use blue or use a mixture of both.
Does Prestone antifreeze contain phosphates?
Prestone® Antifreeze/Coolant is completely safe for use in both foreign and domestic vehicles. For those consumers who would feel more comfortable using a phosphate-free antifreeze, our Prestone® Extended Life 5/150 Antifreeze/Coolant is phosphate, silicate, and borate free.
Does Prestone 50/50 contain silicates?
Prestone Regular or 50/50 is a silicate free OAT antifreeze. It uses phosphates to replace the silicates. It contains no phosphates if you must. You can use any coolant that is phosphate free.
Can you use Prestone antifreeze in a motorcycle?
So long as you use distilled water and NOT tap water to mix prestone or any other recommended coolant, you’re OK.
Are all antifreeze compatible?
All antifreeze falls under one of three basic types. We will give you a brief understanding of each and why they are not compatible with each other. Manufacturers recommended that you change the green IAT antifreeze every 36,000 miles or three years. IAT coolant was used in GM vehicles until 1994.
Can I mix pink and blue coolant?
Part of this also includes making sure that you have enough antifreeze in your car. The last thing you want is for your engine to overheat. These days you can actually get yellow antifreeze, blue antifreeze, pink antifreeze and more. The fact is, mixing these liquids is not safe.
What’s the difference between red and blue antifreeze?
Primarily designed for post-2001 models, red antifreeze has a higher super-additive content than traditional blue antifreeze and will potentially last up to five years. Blue antifreeze, which has a two year service life, will still be available to Trade Club members in the same range of sizes.
