Answers
Answer:
isopropyl benzene (cumene)
Explanation:
The reaction of isopropyl chloride and AlCl3 and benzene belongs to the class of organic reactions known as the Friedel Kraft alkylation.
The mechanism of the reaction involves the formation of a tetrahedral complex [AlCl4]^-.
The electrophile now is the isopropyl group which attacks the benzene to yield the product.

Look at picture
ASAP please will mark as brainlist don’t got much time
Answers
Answer:
are delocalized and move between metal atoms
Explanation:
As the problem says, aluminum has metallic bonds. The main characteristic of metallic bonds is that the electrons are free to move between the metal ions (they are delocalized), thus being responsible for the good electrical conductivity of metals.

Answers
Answer:
I'm not really sure but might be D
One other world-altering discovery that led to both advancement and tragedy is the discovery of nuclear power. Nuclear power has been harnessed for its ability to generate large amounts of energy.
Nuclear science has had significant advancements in various sectors, such as electricity production, medicine, and space exploration. However, the same discovery also led to tragic incidents like the bombings of Hiroshima and Nagasaki during World War II.
These tragic events highlighted the destructive power of nuclear energy and raised concerns about its safety and potential for misuse. Despite the tragic consequences, nuclear power continues to be an important source of energy, but the focus has shifted towards developing safer and more sustainable nuclear technologies.

Melting and boiling point of water is high?
Answers
Answer:
Yes
Explanation:
Why melting and boiling point of water is high?
The reason for the high melting and boiling temperatures is the hydrogen bonding between water molecules that causes them to stick together and to resist being pulled apart which is what happens when ice melts and water boils to become a gas

Write the skeletal formula equation for: solid potassium, K, reacts with

word equation is

The chemical equation using symbols and formula is

(g) ---------> 2KCl (s)
the two reactants are Potassium and Chlorine gas , and the product is Potassium Chloride.
K (s) +
C
l
2
(g) ---------> 2KCl (s)
reactant side K = 1 product side K=2
Cl = 2 Cl =2
the number of Cl atoms on both the sides are equal, in order to balance the number of K atoms on both the sides, we add one K on the reactant side.
2K (s) +
C
l

(g) ---------> 2KCl (s)
reactant side K = 1 + 1= 2 product side K=2
Cl = 2 Cl =2
the equation is now balanced.

The reaction heated up 100 g of water in the beaker from 25 °C to 50.0 °C. The specific heat capacity of water is 4.184 J/g°C. Calculate the amount of heat energy that was released by the reaction.
Answers
Answer:
The amount of heat energy that was released by the reaction is 10,460 J.
Explanation:
Sensible heat is that which a body or an object receives or releases and causes its temperature to increase or decrease without affecting its molecular structure and therefore its state.
In other words, sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state (phase change). When a body is supplied or absorbed sensible heat, the temperature varies.
The equation that allows calculating heat exchanges is:
Q = c * m * ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case:
c= 4.184 [tex]\frac{J}{g*C}[/tex]m= 100 gΔT= Tfinal - Tinitial= 50 C - 25 C= 25 CReplacing:
Q= 4.184 [tex]\frac{J}{g*C}[/tex] *100 g* 25 C
Solving:
Q=10,460 J
The amount of heat energy that was released by the reaction is 10,460 J.
