Answer:
1.17 moles
Explanation:
Since the gas is at the same temperature and pressure, the number of moles should change in direct proporation to the gas volume.
Moles Gas = (0.6 moles)*(30L/15.4L) = 1.17 moles
Answer:
Explanation:
3Pb(ii)(NO3)2 + 2Fe(iii) ( C2H3O2 )3 ===> 3Pb( C2H3O2)2 + 2Fe(NO3)3
I know you have likely been given this as a homework assignment, but in real life I doubt you would be able to see any reaction taking place. The products are likely both soluble and both ionize, so I don't think you will get any kind of reaction taking place.
The equation however is balanced.
NEUTRONS = MASS NUMBER - ATOMIC NUMBER
NEUTRONS = 31 - 15
NEUTRONS = 16
This type of water pollution is known as thermal pollution. Thermal pollution is the release of heat into the environment. In the case of power plants they release heated water into waterways. Water is used in power plants to cool down machinery. As machines operate they release heat so the water is used as a coolant. Releasing heated water into an aquatic ecosystem reduces the oxygen carrying capacity of the water, so less oxygen is available for organisms to use for respiration.
A rock is definitely more dense. If you were to put a cloud in water it would float/stay above it and a rock would sink to the bottom
