HOPE I helped :]

Answer 2

Answer:

stationary front

Explanation:

on a weather map, a stationary front is shown as alternating red semicircles and blue triangles like in the image at the left. notice how the blue triangles point in one direction, and the red semicircles point in the opposite direction.

Which compounds can be made with the reaction benzene via electrophilic aromatic substitution using isopropyl chloride and AlCl3 as reagents (1 equivalent or excess).

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.

How many moles of silver would precipitate out when 3.6 x 10^23 atoms of zinc are combined in silver nitrate according to the following unbalanced equation? (Balance equation first!)

Zn + AgNO3 → Zn(NO3)2 +Ag

A: 1.67 moles
B: 1.2 moles
C: 3.34 moles
D: 0.6 moles

Can someone please help me with this I don’t get it at all.

Answers

Answer:

D: 0.6 moles

Explanation:

First we balance the equation:

Zn + AgNO₃ → Zn(NO₃)₂ + Ag

There are two NO₃ species on the right side, so we put a two before  AgNO₃:

Zn + 2AgNO₃ → Zn(NO₃)₂ + Ag

Now we put a two before Ag on the right, to balance the Ag atoms:

Zn + 2AgNO₃ → Zn(NO₃)₂ + 2Ag

The equation is now balanced.

Now we convert 3.6x10²³ atoms of zinc to moles, using Avogadro's number:

3.6x10²³ atoms ÷ 6.023x10²³ atoms/mol = 0.6 moles

Then we convert 0.6 moles of zinc into moles of silver, using the stoichiometric coefficients of the balanced equation:

0.6 mol Zn * [tex]\frac{1molAg}{1molZn}[/tex] = 0.6 mol Ag

Thus the answer is option D.

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

Explanation:

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 C

Replacing:

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.

Assuming that you mean 10^-4 M then this would be basic and would have a pH of 10.

pOH = -log[OH].
So pOH = 4

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.
