Answer:

37.5g

Explanation:

The half-life is the time taken for a radioactive substance to decay to half its original composition;

 Original composition here is  = 4800g  of U-238

How many grams remain after 7 half-lives;

 After each life, the uranium reduces by half;

 Amount remaining  = 4800 x (\frac{1}{2})^7  

                                  = 37.5g

After 7 half lives, 37.5g of the original sample will remain.

What gas law applies to aerosol cans being stored in a cool place?
svetlana [45]
Don't really know if this is what your asking but P1/T1= P2/T2 should show how the pressure varies with temperature (V is left out because it's constant since the gas is trapped in an aerosol can). As the temperature rises the pressure rises and if it gets too high then the can explodes, which is why it should be stored in a cool place. There's also PV=nRT might be kind of hard to find moles (n) though.

How does the type of chemical bonds present in a substance affect the substances properties?
SCORPION-xisa [38]
Once a chemical bond is formed, the atoms are rearranged to form a stronger bond, affecting the hardness, malleability, etc. The stronger the bond, the easier a substance will break, or, if its a liquid, it will resist seperation.
