Answer:
d) By turning the electrical current off
Explanation:
This is the only one that fits this situation because all of the other answers help improve the magnetic field.
Nuclear energy produces wastes in the form of spent nuclear fuels, this is normally a mixture of radioactive isotopes and heavy metals, both of which are toxic and pose a great danger to the environment. Additionally, irradiated materials surrounding the reactor which become radioactive from exposure to the radiation produced by the reactor and which should be disposed off at the end of the life of the reactor and processes involved. Also the breeder reactors convert unusable radioactive isotopes into fissionable isotopes, thus allowing more of the fuel to be used and reducing amount of fuel rod waste.
Salt is a mixture,salt is composed of sodium and chlorine,NaCI.Its a compound of two distinct elements that can not be broken down further without changing the properties of the substance.(I hoped that helped)
Answer:
I thinks something bad will happen but science can change so im not sure
Explanation:
Science changes because of diffrent thing like enviorment
The mass of water produced when 4.86 g of butane(C4H10) react with excess oxygen is calculated as below
calculate the moles of C4H10 used = mass/molar mass
moles = 4.86g/58 g/mol =0.0838 moles
write a balanced equation for reaction
2 C4H10 + 13 O2 = 8 CO2 + 10 H2O
by use of mole ratio between C4H10 to H2O which is 2:10 the moles of
H20= 0.0838 x10/2 = 0.419 moles of H2O
mass = moles x molar mass
=0.419 molx 18 g/mol = 7.542 grams of water is formed
