Conduction does not work well in metals.


True or False

Answers

Question :

Conduction does not work well in metals. True or False

Answer:

False, because:

Thermal conduction is defined as the transport of energy due to random molecular motion across a temperature gradient. It is distinguished from energy transport by convection and molecular work in that it does not involve macroscopic flows or work-performing internal stresses.

Or in other words, Conduction is the transfer of heat between two parts of a stationary system, caused by a temperature difference between the parts.

What pressure is exerted by 0.75 moles of a gas at 25°C
in a container with a volume of 1.5 L?

Answers

Answer:

1,239,284pa

Explanation:

Assuming it's an ideal gas we use

PV=nRT

P=nRT/V

then we convert our Temperature into Kelvin

T=25+273.15 =298.12K

we convert our volume into M cubed

1.5L =0.0015 cubic meter

P=nRT/V

P= (0.75×298.12×8.314)/0.0015

P = 1,239,284pa

1.65g of zinc is used to make 8g of zinc iodide. How much iodine is required for this reaction?

Answers

Answer:

6.45 g of iodine, I₂

Explanation:

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

Zn + I₂ —> ZnI₂

Next, we shall determine the mass of Zn and I₂ that reacted from the balanced equation. This can be obtained as follow:

Molar mass of Zn = 65 g/mol

Mass of Zn from the balanced equation = 1 × 65 = 65 g

Molar mass of I₂ = 127 × 2 = 254 g/mol

Mass of I₂ from the balanced equation = 1 × 254 = 254 g

SUMMARY:

From the balanced equation above,

65 g of Zn reacted with 254g of I₂.

Finally, we shall determine the mass of f I₂ needed to react with 1.65 g of Zn. This can be obtained as follow:

From the balanced equation above,

65 g of Zn reacted with 254g of I₂.

Therefore, 1.65 g of Zn will react with = (1.65 × 254)/65 = 6.45 g of I₂.

Thus, 6.45 g of iodine, I₂ is needed for the reaction.

What is the amount of aluminum chloride produced from 40 moles of chlorine and excess aluminum?

Answers

Answer: Molar mass of Al = 26.98 g/mol

mass of Al = 12 g

mol of Al = (mass)/(molar mass)

= 12/26.98

= 0.4448 mol

According to balanced equation

mol of AlCl3 formed = moles of Al

= 0.4448 mol

Answer: 0.445 mol

Chemistry question on enthalpy HELP!!!!

Answers

Answer: The enthalpy change for this reaction is, -803 kJ

Explanation:

The balanced chemical reaction is,

[tex]CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)[/tex]

The expression for enthalpy change is,

[tex]\Delta H=\sum [n\times \Delta H_f(product)]-\sum [n\times \Delta H_f(reactant)][/tex]

[tex]\Delta H=[(n_{CO_2}\times \Delta H_{CO_2})+(n_{H_2O}\times \Delta H_{H_2O})]-[(n_{O_2}\times \Delta H_{O_2})+(n_{CH_4}\times \Delta H_{CH_4})][/tex]

where,

n = number of moles  

Now put all the given values in this expression, we get

[tex]\Delta H=[(1\times -394)+(2\times -242]-[(2\times 0)+(1\times -75)][/tex]

[tex]\Delta H=-803kJ[/tex]

Therefore, the enthalpy change for combustion of methane is, -803 kJ

500.0 mL of a gas is collected at 745 K. What will the volume be at standard temperature?

Answers

Answer:

183.22mL

Explanation:

Using Charles law equation, which is as follows:

V1/T1 = V2/T2

Where;

V1 = initial volume (mL)

T1 = initial temperature (K)

V2 = final volume (mL)

T2 = final temperature (K)

Note that standard temperature of a gas is 273K.

Hence, based on the provided information, V1 = 500.0mL, T1 = 745K, V2 = ?, T2 = 273K

Using the formula; V1/T1 = V2/T2

500/745 = V2/273

Cross multiply

V2 × 745 = 500 × 273

745V2 = 136500

V2 = 136500/745

V2 = 183.22

At standard temperature (273K), the new volume will be 183.22mL.

183 ml

Answers

Answer:

One may conclude that they have an identical number of electrons in their outermost shell, therefore the can be substituted for one another.

Explanation:

Elements in the same family tend to behave similarly in chemical reactions  because they have similar number of valence electrons in their outermost shell and they also have similar chemical properties.

Valence electrons are responsible for reactions between elements. The valence electron makes it possible for atoms to combine and react, therefore, elements in a family behave similarly in chemical reactions because they have an identical number of electrons in their outermost shell.
