If the solutions have the same molality, the salt will produce twice as many dissolved particles (Na+ ions and Cl- ions) but the sugar does not dissociate into particles when dissolved.
Temperature is almost always stated in 'degrees', but there are several different systems. The differences are: -- the size of the degrees -- where their zero-point is, i.e. where they begin counting. Here are a few examples: Celsius: Zero point is the freezing temperature of water. Boiling point of water is called '100 degrees'. So the size of the degree is 1/100 of the difference. Fahrenheit: Freezing point of water is called '32 degrees'. Boiling point of water is called '212 degrees'. So the size of the degree is 1/180 of the difference. Kelvin: Zero point is 'absolute zero' ... the temperature where the 'thermal' motion of all molecules completely stops. Size of one "Kelvin" is the same as one Celsius degree. Freezing temperature of water is 273.15 Kelvins. Rankine (hardly ever used): Zero point is 'absolute zero'. Size of the degree is the same as Fahrenheit. Freezing point of water is 459.67 degrees Rankine. Reaumur (never used any more): Freezing point of water is called 'zero degrees'. Boiling point of water is called '80 degrees'. So the size of the degree is 1/80 of the difference.
When the ocean rises to its highest point, it is called a high tide. This occurs twice a day as a result of the gravitational pull of the moon and the sun on Earth's water bodies.
this is sorta a trick question because you cant have twice as cold, there is no such thing as cold just absence of heat...think about it so say its 100 deg celsius, can you still say twice as cold as 100 deg? nope
One mole of calcium chloride would be more effective than one mole of sodium chloride because calcium chloride provides twice as many ions per formula unit, resulting in a higher concentration of ions in solution. This makes calcium chloride more effective in applications that require dissociation into ions, such as lowering the freezing point of water or enhancing road de-icing.
The metal used as an alloy in ballpoint pens is bismuth. Its strong odor results from the highly toxic bismuth oxide, which forms when bismuth is exposed to air. Bismuth is almost twice as dense as lead, making it a suitable material for use in pens.
Nothing. The freezing point depends on the molecular structure, not the volume of the substance. It will take a longer time to freeze twice the amount of liquid, but the freezing point remains the same.
How much salt and how much sweet?By the way, which freezes "faster" is not a question that scientists tend to study a lot. They're more likely to be interested in the freezing point. At the same temperature, something with a lower freezing point will probably freeze slower, but quantifying this is complicated.Anyhow, that aside, adding any solute to a solvent lowers the freezing point. The amount the freezing point is lowered depends on the solvent and on the amount of solute that was added (measured in moles). Solutes that dissociate into multiple species in solution count multiple times (so adding one mole of table salt, which dissociates into one mole of sodium ions and one mole of chloride ions, lowers the freezing point of a certain amount of water twice as much as adding one mole of sugar, which doesn't dissociate). However, remember that it's the number of moles, not the volume or weight directly, that matters.If you have specific quantities in mind, you could calculate the molality of the resulting solutions (remember that table salt counts twice) and multiply that by the molal freezing point depression of water (about 1.85 K kg/mol) to find out exactly how much the freezing point was lowered in each case.
No, the elevation in boiling point will not be the same for a 0.1 m NaCl solution and a 0.1 m sucrose solution. This is because the elevation in boiling point is directly proportional to the number of particles in the solution, known as the van't Hoff factor. NaCl dissociates into two ions (Na+ and Cl-) in solution, so it has a van't Hoff factor of 2, while sucrose does not dissociate and has a van't Hoff factor of 1. Therefore, the NaCl solution will have a greater elevation in boiling point compared to the sucrose solution.
If you use twice as much solvent, the concentration of the solute in the solution will decrease. This could affect the reactivity of the solute, the solubility of the solute, and the overall properties of the solution. Additionally, the volume of the solution will increase, leading to changes in factors like viscosity, boiling point, and freezing point.
An inverted and smaller real image is produced by a converging lens when an object is placed twice as far as the focal point. The image is located between the focal point and twice the focal length from the lens.
Nope. Other way around. The bass clarinet IS twice as long as the Bb one, and IS an octave lower.
No, in tennis, the ball cannot bounce twice before a player hits it during a single point.
No. For the physical formula ratio, of [solute:solvent] to be the same, you would have to use twice as much glucose as sucrose, to make the solution; because sucrose is a disaccharide. But, when preparing the solution, the actual weight used will be approximately the same. You have a solution, with solute sucrose, at 1C ratio. Weighing the same amount of glucose (in grams), will make a solution of 2C ratio. General expression is Glucose:Sucrose::2:1.
28.6% is 0.286 as a decimal.Tip: Move the decimal point twice to the left when converting into decimal; move the decimal point twice to the right when converting into percentage.
No - the stopping distance depends on the speed of the vehicle - it' not simply a case of 'doubling-up'.
Yes . Freeze it . then unfreeze it . then freeze it again . Keep doing those steps until you get to the amount of freezing or unfreezing numbers you get .
The height of the wave, above the rest position, is its Amplitude. Twice the amplitude is the distance from the deepest point to the highest point.
