Answer: b. The waste generated is hazardous and must be disposed of.
c. Nuclear material can be spilled into the ocean if reactors are near the coast.
d. A large amount of cold water is generated, which must be stored somewhere.
Explanation:
The main environmental costs for produced during the nuclear power plant consists of procurement of fuel and the thermal load is also produced with cold water discharge in the sea. This can contaminate the sea, hence, must be stored somewhere. The nuclear waste consists of radioactive substances which are hazardous for the environment. The nuclear based electricity does not produce carbon dioxide.
There are 34 g of oxygen in the container.
We can use the<em> Ideal Gas Law</em> to solve this problem.
But , so
and
STP is 0 °C and 1 bar, so

Answer:
Explanation:
Data Given
Formula of hydrazine = N₂H₄
Lewis structure of hydrazine (N₂H₄) =?
Solution:
- Hydrazine (N₂H₄) contains 2 Nitrogen atoms and 4 Hydrogen atoms
- Nitrogen atom have 5 valence electrons
- Hydrogen have 1 valance electron
- So it have 14 total number of valance electrons
N₂ H₄ = 2 (5) + 4(1) = 14 no. o electrons
- it is a stable compound and obey octet rule for nitrogen and duplet rule for hydrogen by sharing of electrons.
To draw the Lewis Structure
- Put the 2 nitrogen in center and draw the Hydrogen on the outside
- Put the 2 hydrogen on out side of each of the nitrogen
- Then draw the 2, 2 valence electrons between atoms that form chemical bond
- So we will draw total 14 electrons in the structure
- then we count electrons around each atom of nitrogen and hydrogen that it have 8 and 2 electrons to complete its octet and duplet respectively
Lewis Structure of N₂ H₄ in attachment
Answer:
Kinetic Energy
Explanation:
Temperature is a measure of the average kinetic energy of the particles in a substance. And also Kinetic Energy has 2 words.
