Answer:
Pb(No3)2+2Nacl_PbCl2+2NaNO3
<u>Answer:</u> The correct answers are 
<u>Explanation:</u>
To find the polynomials which could represent the are of a square having side x greater than 2, we need to find the value of 'x' for all the given polynomials.
From the given options:
- 1.
x = -3 is ignored.
- 2.
x = -10 is ignored
- 3.
To solve this we use the quadratic formula:
Putting values of a, b and c, we get:
As, x comes out to be 2 and is not greater than 2. Hence, this is not considered.
- 4.
Solving for 'x' by splitting the middle term:
Hence, this is ignored.
- 5.
Solving for 'x' by splitting the middle term:
Hence, this is ignored.
So, the correct polynomials are
Answer:
- <u>Decreasing the temperature of the system will shift the reaction rightward.</u>
Explanation:
The complete question is:
Given the equation representing a system at equilibrium:
- N₂(g) + 3H₂(g) ⇌ 2NH₃(g) + energy
what changes occur when the temperature of this system is decreased?
<h2>Solution</h2>
Modifying the temperature of a system in equilibrium changes the equilibrium constant and the equilibrium position (concentrations) of the system.
When the temperature is decreased, following LeChatelier's principle that the system will react in a way that seeks to counteract the disturbance, the reaction will shift toward the reaction that produces more heat energy to compensate the temperature decrease.
Thus, decreasing the temperature of the system will favor the forward reaction, more N₂(g) and H₂(g) will be consumed and more NH₃(g) and energy will be produced. Hence, the equilibrium will shift rightward.
Answer:

because we need to learn new things
Answer:
The bulk of nuclear waste is in the form of <u>solid ceramic pellets</u>.
Explanation:
Nuclear fuel loaded into commercial reactors is generally in the form of solid ceramic pellets that are stacked into metal tubes and bundled together in fuel assemblies. After the atoms in the pellet split to release their energy, the pellets in tubes emerge as nuclear waste.
