How can you test if petrol or diesel is in spare fuel tank?
Take a sample out and check following; Colour - Petrol is almost clear, diesel is more yellowy Smell - Diesel and Petrol both have distinctively different smells, only way is if you get a sample of either as a reference Flash point - Petrol has a much lower flash point so will burn if ignited whereas diesel wont. If you take a very small sample and under safe and controlled circumstances try to ignite with a match if burns is petrol if not diesel Hope this helps

Why petrol on a wet surface appear coloured?
i believe petrol appear colored when present on wet surfaces because of its chemical composition. given that each petrol sample contain various bonds and bond angles, the presence of petrol on water (since petrol is insoluable in water), causes the light being reflected from the petrol appear in rainbow colours (ROYGBIV) since each colour has a different wave lenght
What will be the sample size?
Number of Sample in set of observation.
Is a sample a number describing some characteristic of a statistic?
No. A statistic is a number describing a characteristic of a sample.
What is the number of ions in a 6.58 mole sample of NaCl?
The number of ions in a 6,58 mole sample of NaCl is 79,25137367812.10e23.
What is absolute sample size?
It is the number of elements in the sample. By contrast, the relative sample size is the absolute sample size divided by the population size.
How do you find the sample mean?
Add the values of the variable for all elements in the sample and divide by the number of elements on the sample.
How many lb-moles of substance are present in the given sample?
To determine the number of lb-moles in a sample, divide the weight of the sample in pounds by the molecular weight of the substance. This will give you the number of lb-moles present in the sample.
A liquid sample contains hexane and octane whose boiling points are79.0 celsius and 136 celsius respectively what method would be used to separate the two components explain?
Distillation would be the method used to separate hexane and octane from the liquid sample. This process takes advantage of the difference in boiling points between the two components to vaporize and then condense each one separately. The lower boiling point component (hexane) will vaporize first, allowing it to be collected and separated from the higher boiling point component (octane).
Is the number of atoms in a sample directly related to the mass of that sample?
If the chemical composition of the sample is known, then the answer is yes. However, equal masses of platinum and magnesium, for example, contain quite different numbers of atoms, because the atomic mass of platinum is much higher than that of magnesium.
What is the formula for calculating the mean of a sample, represented by the symbol "" in statistics?
The formula for calculating the mean of a sample, represented by the symbol "" in statistics, is to add up all the values in the sample and then divide by the total number of values in the sample. This can be written as: x / n, where x represents the sum of all values in the sample and n is the total number of values in the sample.
