Answer:
B.
Explanation:
Because the delocalised electrons are free to move.
Metallic bonds are formed by the electrostatic attraction between the positively charged metal ions, which form regular layers, and the negatively charged delocalised electrons. These are the electrons which used to be in the outer shell of the metal atoms. These delocalised electrons are free to move throughout the giant metallic lattice, so as one layer of metal ions slides over another, the electrons can move too keeping the whole structure bonded together.
This is the opposite of what happens in a giant ionic lattice, where both the positive ions and the negative ions are locked in place. If the crystal is stressed and one layer moves with respect to another, the positive ions can end up lined up with each other, and the negative ions lined up with each other. This causes repulsion, so the crystal fractures.
Answer:
THE ANSWER IS
<em>C. St. Louis</em>
Explanation:
Do you see that big, slightly curved line overlapping the united states, with little triangles in it? That represents the heavy rainstorm. If you look close enough, St. Louis is closest to one of the tiny triangles, aka the rainstorm.
WHY IT CAN’T BE THE OTHER OPTIONS:
It cannot be the <em>other choices</em> because they are not as close to the line as <u>St. louis </u>is

Kp/Kc = RT
<h3>Further explanation</h3>
Given
Reaction
A(g) ⇌ C(g)+B(g)
Required
Kp/Kc
Solution
For reaction :
pA + qB ⇒ mC + nD
While the equilibrium constant Kp is based on the partial pressure
The value of Kp and Kc can be linked to the formula '
R = gas constant = 0.0821 L.atm / mol.K
Δn=moles products - moles reactants or
number of product coefficients-number of reactant coefficients
For reaction :
A(g) ⇌ C(g)+B(g)
number of product coefficients = 1+1=2
number of reactant coefficients = 1
Δn= 2 - 1 =1
So Kp/Kc = RT
Answer: Fusion is the binding together of two smaller atoms into a larger atom. Both are examples of nuclear chemistry and both produce large amounts of energy. There are two main advantages of fusion over fission. ... The other main advantage is that fusion does not produce radioactive, toxic waste products like fission does.
All of them are the current biggest sources of electrical energy.
3 of them will be explained.
------------------------
1) Natural gas:
it was the largest source, 38 % approx., of the USA electricity generation. It is used in steam turbines and gas turbines to generate electricity.
----------------------
2) Nuclear energy:
It was the source of 19% of the U.S. electricity generation in 2021. Nuclear power plants use steam turbines to produce electricity from fission.
---------------------
3) Coal power:
It was the 2nd.-largest energy source for US electricity generation in 2021.
