The color of light given off when a sample is heated corresponds to?
The color of light given off when a sample is heated corresponds to the energy levels of the electrons in the atoms of the sample. Each element emits light at specific wavelengths, creating a unique spectral signature that can be used to identify elements. This phenomenon is known as atomic emission spectroscopy.
What is Slovin's formula?
Slovin's formula is a mathematical formula used to determine the sample size needed for a survey or study. It takes into account the population size, desired level of confidence, and margin of error to calculate the appropriate sample size for a given study. It is commonly used in statistics and research to ensure accurate and reliable results.
Why density is the criteria for purity with respect to chemistry?
Mass and volume are extensive properties, which are dependent upon the size of the sample. A larger sample will have a greater mass and volume than a smaller sample. Density is an intensive property, which does not depend on the size of the sample. Density is a ratio of mass to volume, which does not vary with the size of the sample. The density of a larger sample will be the same as the density of a smaller sample.
What is the half-life of a radioactive sample of bromine-74 in 25 minutes in a 4mg sample?
The question does not make sense. The half-life of bromine-74 is, in fact, 25.4 minutes. In 25 minutes, that 4mg sample will decay to 2mg. In 25 more minutes it will decay to 1mg. In 25 more minutes it will be 0.5mg. And so on and so forth. If you meant to ask how much will remain after a given period of time, please restate the question.
What kinds of matter are present in any amounts?
In any given sample of matter, you can typically find elements, compounds, and mixtures present in varying amounts. These can include atoms, molecules, ions, and particles such as electrons and protons. Each type of matter contributes to the overall composition and properties of the sample.
What are numbers that are close to the given numbers to make estimation easier?
15 ,67, and 84 are numbers that are close to the given numbers to make estimation easier.
What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample
When need rough estimation?
A rough estimate is given when the situation does not require the exact numbers to be given.
How many moles are in 61.83 g H3BO3?
To find the number of moles, divide the given mass of H3BO3 by its molar mass. The molar mass of H3BO3 is calculated as (31.01) + (111) + (3*16) = 61.83 g. Therefore, 61.83 g H3BO3 is equal to 1 mole of H3BO3.
Why is ortho-boric acid called ORTHO boric-acid?
Ortho-boric acid is called "ortho" to distinguish it from other forms of boric acid, like meta-boric acid and pyro-boric acid. The term "ortho" indicates the position of the hydroxyl groups on the boron atom in its molecular structure. In the case of ortho-boric acid, the hydroxyl groups are adjacent to each other on the same boron atom, distinguishing it from the other forms.
What is a blood sample?
A blood sample is a sample given for medical purposes as a blood test.
How to find the percent by mass of a compound in a given sample?
To find the percent by mass of a compound in a given sample, you need to divide the mass of the compound by the total mass of the sample and then multiply by 100. This will give you the percentage of the compound in the sample.
