Which of the following does not apply to water molecules?

Water molecules are polar
Water has cohesive properties
Water is less dense as a solid than a liquid
Water is not a very good solvent

Answers

Answer:

It is the last one.

Explanation:

Water molecules are polar, they have cohesive properties, and water is less dense when it is solid than when it is a liquid, that is why ice floats in liquid water. However, water is a very good solvent, it can dissolve many solids, including sugar, salt, and other hydrophilic substances.

Volume in liters of carbon dioxide produced at stp when 0.85 grams of butane reacts

Answers

Volume in liters of Carbon dioxide : 0.672

Further explanation

Reaction(combustion of butane-C₄H₁₀)

2C₄H₁₀+13O₂⇒8CO₂+10H₂O

mol butane (MW=58,12 g/mol) :

[tex]\tt \dfrac{0.85}{58,12}=0.015[/tex]

mol CO₂ : mol C₄H₁₀ = 8 : 4, so mol CO₂ :

[tex]\tt \dfrac{8}{4}\times 0.015=0.03[/tex]

At STP, 1 mol = 22.4 L, so volume CO₂ :

Calculate how much Carbon Dioxide IN GRAMS needs to be absorbed to
release 500g of oxygen during photosynthesis.

Answers

Answer:

687.5 g of CO2

Explanation:

We'll begin by writing the balanced equation for photosynthesis. This is illustrated below:

6CO2 + 6H2O —> C6H12O6 + 6O2

Next, we shall determine the mass of CO2 absorbed and the mass of O2 released from the balanced equation. This is illustrated below:

Mass of CO2 = 12 + (2 × 16) = 12 + 32

= 44 g/mol

Mass of CO2 from the balanced equation = 6 × 44 = 264 g

Molar mass of O2 = 2 × 16 = 32 g/mol

Mass of O2 from the balanced equation = 6 × 32 = 192 g

Summary:

From the balanced equation above,

264 g of CO2 were absorbed to release 192 g of O2.

Finally, we shall determine the mass of CO2 absorbed to release 500 g of O2. This can be obtained as follow:

From the balanced equation above,

264 g of CO2 were absorbed to release 192 g of O2.

Therefore, Xg of CO2 will be absorbed to release 500 g of O2 i.e

Xg of CO2 = (264 × 500)/192

Xg of CO2 = 687.5 g

Thus, 687.5 g of CO2 will be absorbed to release 500 g of O2.

How much heat is required to raise the temperature of a 6.21 g sample of iron from 25.0 oC to 79.8 oC?

Answers

Answer:

151.1J

Explanation:

Given parameters:

Mass of iron  = 6.21g

Initial temperature of iron  = 25°C

Final temperature of iron  = 79.8°C

Unknown:

Amount of heat = ?

Solution:

The amount of heat require to cause this temperature can be determined using the expression below;

    H  = m c (T₂ - T₁)

H is the amount of heat

m is the mass

c is the specific heat capacity

T is the temperature

    Specific heat capacity of iron 0.444J/g°C

Insert the parameters and solve;

     H  = 6.21 x 0.444 x (79.8 - 25)

     H   = 151.1J

Below is a phase diagram for Carbon Dioxide. Use this diagram to answer the following question.
In this example we will start the Carbon Dioxide out at a temperature of -20oC and 1 atm of pressure. If the pressure was raised to 100 atm of pressure while still staying at -20oC, what phases would the Carbon Dioxide change between?

Answers

If you mark those points on the phase diagram it appears to be moving from vapor to liquid. If you can’t see how I determined that please let me know and I can further explain.

Vapor to liquid is the same as saying gas to liquid, which I believe to be the correct answer.
