Answer:
D
We don't have a way to contain the radioactive waste produced.
Explanation
Nuclear waste is non disposable and takes millions of years to biodegrade and lose it radio activeness
The last option, fossil fuels are non-renewable sources.
Answer:
true
Explanation:
because if you really take a moment to think about it atoms are made of molecules.
<h3>
Answer:</h3>
0.95 atm
<h3>
Explanation:</h3>
We are given;
Initial pressure, P1 = 1.0 atm
Initial temperature, T1 =298 K (25°C + 273)
Initial volume, V1 = 0.985 L
Final temperature, T2 = 295 K (22°C + 273)
Final volume, V2 = 1.030 L
We are required to find final air pressure;
Using the combined gas law;
To get, P2 ;
= 0.95 atm
Therefore, the air pressure at the top of the mountain is 0.95 atm
Answer:
Molecules in order of decreasing rate of effusion:
Explanation:
Mass of gas=
Mass of gas =
Mass of gas =
Mass of gas =
According Graham's law:
'The rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas'.The equation given by this law follows the equation:
So, higher the molecular mass of the gas lower will be the effusion rate and vice versa.
Increasing order of molecular masses of the given gases:
Decreasing order of effusion rate respective to gases:
Molecules in order of decreasing rate of effusion:
