What term describes how much matter a substances contains?
Mass decribes how much matter a substance contains and Mole decribes the quantity of matter contained in a substance.
How much energy is released when a substance is cooled to its original temperature?
When a substance is cooled to its original temperature, no energy is released. Cooling a substance typically involves removing energy from the substance, but this process does not generate energy. The energy removed is used to lower the temperature of the substance.
What are the differences between solubility and reactivity?
Solubility - How much a substance can dissolve.Reactivity- How much a substance reacts with something else.Hope this helps.
What is the measurement of how much heat energy is required for a substance to melt?
The measurement of how much heat energy is required for a substance to melt is called the heat of fusion. It is the amount of energy required to change a substance from a solid to a liquid at its melting point.
30 gram of a radioactive substance that has a half-life of 2 days after 2 days how much will be left?
With radioactive decay, predicting when any individual atom will decay is nearly impossible. However, when a lot a particles are present, then it is possible to get a general idea of how much will decay in a certain period of time. The half-life is this measurement, and it is the time that it takes for one halfof the substance to decay. Hence half-life or how long it takes for half to "die".For any size sample of a substance, the half-life is how long it takes for half to be left, so for a substance with a half-life of 2 days, half of the substance will decay in two days. Therefore your answer is simply half of 30g which is 15g.Additional reading: http://simple.wikipedia.org/wiki/Radioactive_decay
Is ammonia bad for your skin?
Yes. Ammonia is a caustic substance and can cause chemical burns to skin. You should avoid contact as much as possible. If contact does occur and it burns at all, flush the exposed area with running water.
What is the relationship between the heat of combustion and the stability of a substance?
The heat of combustion is a measure of how much energy is released when a substance burns. Generally, substances with higher heat of combustion are more stable because they require more energy to break their bonds and ignite.
Why is density a characteristic of a substance and volume and mass are not?
The volume and mass of a substance are independent of the substance itself, but depend upon how much there is of the substance The density of a substance is the relation between how much volume you have of a substance and how much mass that volume has (and vice-versa). It is independent of how much there is of the substance and is thus a characteristic of the substance.
How much radioactive sample will be left at the end of two weeks?
That would depend on the initial amount of the substance, as well as on its half-life.
How much does Cory Burns weigh?
MLB player Cory Burns weighs 204 pounds.
What is the equation to calculate the percentage of each substance in a mixture?
(percentage)x(how much of the substance)+(percentage)x(how much of the substance)=(total percentage)(total of substance)
What does OD mean in science?
In science, OD typically stands for "optical density," which is a measure of how much light is absorbed or scattered by a substance. It is commonly used in spectrophotometry to quantify the concentration of a substance in a solution.
How much is ken burns worth?
54 million
How many milliliters in 650 milligrams?
That depends on the density of the substance. The density tells you, precisely, how much mass a substance has per unit of volume.That depends on the density of the substance. The density tells you, precisely, how much mass a substance has per unit of volume.That depends on the density of the substance. The density tells you, precisely, how much mass a substance has per unit of volume.That depends on the density of the substance. The density tells you, precisely, how much mass a substance has per unit of volume.
What is ratioactive dating called?
Radiocarbon Dating. It measures the levels of carbon 12, a radioactive substance in everything, and based on how much is left scientists can determine how old something is.
Dose salt or sugar affect water evaporation?
No. The water is simply evaporated as normal and the salt or sugar (or pretty much any substance that can be mized with water) is left behind.
Why does fire burn fast?
Fire does not burn, its whatever if fueling the fire that burns. For example, wood is a fuel that burns, and fire is the result. The speed at which a fuel burns, depends on the fuel. i.e. Wood burns much slower than gasoline.
