Answer:
The average kinetic energy of a gas depends only on its temperature.
Explanation:
The average kinetic energy of particles in a gas can be found using the equation
,
where
- is the Stefan-Boltzmann constant, and
- is the absolute temperature of this gas (the one in degree Kelvins.)
As seen in this equation, the average kinetic energy of particles in a gas depends only on the temperature of the gas. Also, since the question is asking for the average not the total kinetic energy, the number of particles in this gas doesn't matter, either.
Answer: 46.875%
the moles of C2H6 is 32/(12.2+6) = 16/15 (mol)
the moles of CO2 is 44/(12 + 16.2) = 1 (mol)
have:
2C2H6 + 7O2 ⇒ 4CO2 + 6H2O
0,5 <= 1
=> C2H6 reacts 0.5 mol
=> H = %

Answer:
The precautionary principle would prevent the implementation of technologies that possess a risk to humans, animals, and the environment. The strengths are that it will definately save the population and planet from a new technology that could cause long-term harm.
The weakness is that this principle may inhibit new technologies that are needed to help under-developed countries from preventing diseases. The precautionary principle states that technologies should entirely risk-free.

Let's look at the choices and see why they work, or don't work.
monosaccharide
* Otherwise known as a simple sugar. And NaCl is definitely not a sugar of any type. So this is wrong.
disaccharide
* Complex sugar. And NaCl doesn't qualify either.
organic
* A definition of an organic compound is one that has carbon in it. NaCl has sodium and chlorine. No carbon at all, so this isn't the right answer. And I wish that organic was an earlier choice, since the sugars mentioned above are organic compounds.
inorganic
* This is the only possible choice. Salt is not an organic compound since it doesn't have carbon. So it can't be a sugar either. But it can and is inorganic.</span>
Answer:
The correct option is: It becomes one-half as large.
Explanation:
The energy stored in a capacitor is inversely proportional to the distance between plates.
If the plate separation (distance between plates) is doubled, it means the Energy stored will be halved. That is, the energy stored becames one-half as large.
