How many grams of aluminum chloride are needed to react completely with 1.084g lithium sulfide?

Answers

Answer 1

Answer: Molar mass :

Li₂S = 45.947 g/mol

AlCl₃ = 133.34 g/mol

3 Li₂S + 2 AlCl₃ = 6 LiCl + Al₂S₃

3 * 45.947 g Li₂S ----------> 2 * 133.34 g AlCl₃
1.084 g Li₂S ----------------> ?

Mass Li₂S = 1.084 * 2 * 133.34 / 3 * 45.947

Mass Li₂S = 289.08112 / 137.841

Mass Li₂S = 2.0972 g

hope this helps!

A hexagon can be used to represent the structure of cyclohexane. What does each side of the hexagon represent?

Answers

Answer:

Single bond between two carbon atoms.

Explanation:

Let us look at the structure of a hexagon for representation of cyclohexane.

Cyclohexane has six carbons and thus we can place each carbon at the vertices of the hexagon. Now the bond joining each adjacent carbon atoms will be shown by the each side of the hexagon.

The hydrogen atoms are not shown in the structure.

Answer:

Single bond between two carbon atoms.

Write a short note on the causes and effects of global warming and acid rain.

Answers

Answer:

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Acid rain affects nearly everything. Plants, soil, trees, buildings and even statues can be transformed by the precipitation.

Calculate the heat energy for this scenario: You are repeating the food experiment we did in class with a different food snack. At the beginning of this experiment, you started with 25 grams of water at 22 deg * C At the end of the experiment, the final temperature of the water is 45°C. The specific heat of water is 4.18J / (deg) * CSub and solve

Answers

Answer:

Mass of water (m) = 25 grams = 0.025 kg (since 1 g = 0.001 kg)

Specific heat of water (c) = 4.18 J/(g°C) = 4.18 J/(kg°C)

Initial temperature ( $T_ {initial}$ ) = 22°C

Final temperature ( $T_(final)$ )= 45°C

Change in temperature (ΔT):

ΔT= $T_(final)$ - $T_ {initial}$ =45°−22°=23°

Now, calculate the heat energy (Q)

Q=mass×specific heat×ΔT

Q=0.025kg×4.18J/(kg°C)×23°C

Q≈2.44kJ

So, the heat energy for this scenario is approximately 2.44 kilojoules (kJ).

A gas occupies 12.3 l at a pressure of 40 mm hg. what is the volume when the pressure is increased to 60 mm hg

Answers

From boyles law.
P1v1=P2v2
So,12.3×40=v×60
V= 12.3×40/60
8.2

Boyle's Law states an inverse relationship between volume and pressure. If the constant of proportionality is 12.3×40 which is 492, the volume would be 492÷60 which is 8.2.

Answer is 8.2 I
