If a specimen of a given radioactive substance is reduced in size its half life?
The half-life of a radioactive substance is an intrinsic property that does not change regardless of the size of the specimen. Whether the sample is large or small, the time it takes for half of the radioactive atoms to decay remains constant. Therefore, reducing the size of the specimen does not affect its half-life.
After 3 half lives of a radioactive substance remains A al B one half C one third D one eighth?
After 3 half lives, the original substance will be reduced by a factor of 2 each time. So after the first half-life, it will be reduced to half (A al B). After the second half-life, it will be reduced to one-quarter (A al C). After the third half-life, it will be reduced to one-eighth (A al D).
What will happen if the ozone layers is reduced by 40 percent?
If the ozone layer is reduced by 40 percent, UV will enter. This will cause extinction of life.
The substance that accepts electrons from another substance is the?
In a redox reaction, the substance that accepts electrons is said to be the substance reduced. This substance is also likely the oxidizing agent, since oxidation is the loss of electrons.
How can you determine whether a measured value of a substance represents an extensive property?
Its value will be reduced as the numbers of moles of the materials is reduced
How do you determine the half life of a radioactive substance that has changed through radioactive decay After 40 days the original substance left is is one sixteenth of the original amount?
To determine the half-life of the substance, you can use the fact that after one half-life, the substance will be reduced to half of its original amount. In this case, after 40 days, the substance is reduced to one sixteenth of its original amount, which represents 4 half-lives (since 1/2^4 = 1/16). Thus, each half-life of this substance is 10 days.
What is the relationship between oxidising agent and the reduced substance?
Its the substance reduced which is termed to be an oxidizing agent. When a substance is reduced, it loses electrons that are taken up by another substance thereby oxidizing another substance (oxidising agent).
When a substances gains electrons is it reduced?
Yes when any substance gains electrons , that substance is now then reduced.
What is 77.3 percent as a reduced fraction?
77.3 percent as a reduced fraction is 773/1000.
What is the reduced percent when price reduced from 25 to 10?
Reduced 60%
How do you write 0.036 percent as a reduced fraction?
0.036 percent as a reduced fraction = 9/25000
A substance that can not be reduced to a simpler substance by chemical means?
An "element"
After 3 half lives of a radioactive substance remains A al B one half C one third D one eighth?
After 3 half lives, the original substance will be reduced by a factor of 2 each time. So after the first half-life, it will be reduced to half (A al B). After the second half-life, it will be reduced to one-quarter (A al C). After the third half-life, it will be reduced to one-eighth (A al D).
What is 6 percent as a reduced fraction?
6 percent as a reduced fraction is 6/100 = 3/50.
What is a reduced fraction to equal 10 percent?
The reduced fraction to equal 10 percent is 1/10
What is 15 percent reduced 52.80?
52.80 reduced by 15% = 44.88
What is 17.5 percent reduced by 780?
780 reduced by 17.5% is 643.5
