What kind of mixtures can be separated by distillation? Fractional distillation is a method for separating a liquid from a mixture of two or more liquids. For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling […]
What would happen if the population of rabbits increased?
What would happen if the population of rabbits increased? There would be more food for the rabbits and slugs, so their populations would increase. However, there would be less food for the frogs and voles, so their populations would decrease. This means less food for the foxes and hawks. How did doubling the rabbit population […]
How do you find the class interval in a frequency distribution?
How do you find the class interval in a frequency distribution? The steps in grouping may be summarized as follows: Decide on the number of classes. Determine the range, i.e., the difference between the highest and lowest observations in the data. Divide range by the number of classes to estimate approximate size of the interval […]

What is the pressure of 0.540 mol of an ideal gas at 35.5 L and 223 K Brainly?
What are the 4 main parts of a spiral galaxy?
What are the 4 main parts of a spiral galaxy? A galaxy contains stars, gas and dust. In a spiral galaxy like the Milky Way, the stars, gas, and dust are organized into a “bulge,” a “disk” containing “spiral arms,” and a “halo.” Elliptical galaxies have a bulge-like central region and a halo, but do […]
What does it mean when cats sit and stare at you?
What does it mean when cats sit and stare at you? If your cat looks relaxed and calm when staring at you, they’re looking at you for happy reasons and are likely just showing you affection. How do cats choose their human? Cats’ favoritism is just as unpredictable and individual. Your cat’s favorite person might […]
Can you convert current to voltage?
Can you convert current to voltage? We usually say that the resistor converts the current IIN into a proportional voltage VOUT or it serves as a simple current-to-voltage converter – a linear circuit with transfer ratio k = VOUT/IIN [V/mA]. A bare resistor can convert current into voltage. How do you convert low current to […]
What does a sharp knife cut better than a blunt one?
When light falls on a metal surface the maximum kinetic energy depends on?
When light falls on a metal surface the maximum kinetic energy depends on? When light falls on a metal surface, the maximum kinetic energy of the emitted photo-electrons depends upon the frequency of the incident light. Do all electrons ejected from the metal surface have the same kinetic energy? No, it is not necessary that […]
