<u>Advantages of Nuclear Fission</u>
-
Nuclear fission provides cheapest energy . Almost 10% of electricity used in the world is obtained from the fission reaction
- It offers a low-emission energy solution since there is no carbon dioxide gas emitted during the nuclear fission reaction
- A well controlled and maintained nuclear reactor can produce energy for 36 to 40 months so works for .
- It is a reliable source of energy as energy is obtained from uranium which is available is plenty.
- It provides very concentrations of energy as it can provide large amount of energy from small amount of fuel.
- The reaction gives less annual mortality rate of any energy resource with 90 deaths per trillion kilowatt hours
<u>Disadvantages of Nuclear Fission
</u>
- It is dangerous and also explosive.
- It creates harmful and radioactive waste products.
- It is not a renewable energy resource like solar and wind energy
- It can develop long-term health issues for people exposed to then radioactive waves.
- It involves high cost in installation of the reactors.
Answer:
na
Explanation:
because it has more atomic radius in it
Answer:
None of the options are correct.
The correct answer is 1.10g
Explanation:
First, we'll begin by balancing the equation given above. This is illustrated below:
2HCl + 2Na —> 2NaCl + H2
Next, let us calculate the mass of HCl that reacted and the mass of H2 produced from the balanced equation. This is illustrated below:
Molar Mass of HCl = 1 + 35.5 = 36.5g/mol
Mass of HCl from the balanced equation = 2 x 36.5 = 73g
Molar Mass of H2 = 2x1 = 2g/mol
Now we can easily find the mass of H2 produced when 40g of HCl reacted as shown below:
From the balanced equation,
73g of HCl produced 2g of H2.
Therefore, 40g of HCl will produce = (40 x 2)/73 = 1.10g of H2.
From the calculations made above,
40g of HCl produced 1.10g of H2
1) Equilibrium reaction:
<span>2NO2 <----> N2O4 + 57.2 kJ
2) The quantity 57.2 kJ on the right side indicates that the reaction generates heat, i.e. it is exothermic.
When you increase the temperature of an equilibrium chemical reaction that is exothermic you displace the equilibrium to the left, meaningh that more ractant will be formed..
Answer: the equilibrium will be displaced to the left producing more reatant, NO2.

Answer:
your answer is 30f
Explanation:
The coldest possible temperature, or absolute zero, is -273.15 degrees Celsius, or 0 degrees Kelvin. So, 10 degrees Celsius (and this shouldn't be taken too literally) is in fact only about 1.8 per cent warmer than 5 degrees, and 30 degrees is only about 5.2 per cent warmer than 15 degrees.
