Answer: acceleration= Change in velocity/ change in time
Explanation:
A= Delta v/ delta t
FeBr₃ ⇒ limiting reactant
mol NaBr = 1.428
<h3>Further explanation</h3>
Reaction
2FeBr₃ + 3Na₂S → Fe₂S₃ + 6NaBr
Limiting reactant⇒ smaller ratio (mol divide by coefficient reaction)
211 g of Iron (III) bromide(MW=295,56 g/mol), so mol FeBr₃ :
186 g of Sodium sulfide(MW=78,0452 g/mol), so mol Na₂S :
Coefficient ratio from the equation FeBr₃ : Na₂S = 2 : 3, so mol ratio :
So FeBr₃ as a limiting reactant(smaller ratio)
mol NaBr based on limiting reactant (FeBr₃) :
<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.
If your body temperature falls to 95°F (35°C) or lower, you have “hypothermia.” This condition can potentially lead to cardiac arrest, brain damage, or even death. If your body temperature rises as high as 107.6°F (42 °C), you can suffer brain damage or even death.
