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.

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.

Answer:

183 ml

Electrons are important in chemical reactions. Since the elements in a family tend to behave similarly in chemical reactions, one may conclude that:

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.

mass of Al = 12 g

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

= 12/26.98

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

A Good Day for a Bad DecisionHave you ever noticed that some people always seem to make the right choices? They may be the person who always picks the right pitch to swing at, or the one who always picks the pair of shoes that quickly become a popular fad. On the other hand, some people never seem to make a good decision. They may be the kids who ride a bike down a steep hill and crash into a bush or the ones who step to the edge of a sidewalk in time to get splashed by a car. How do some always seem to be living the good life while others seem doomed to misery? Is this just a matter of luck?While luck probably has something do with it, the better explanation may be that the two groups have differences in the development of their brains. You see, most adult humans use their cerebral cortex to make decisions. The cerebral cortex is the part of the brain in the front of your head that deals with how you perceive the world and respond appropriately. It also helps you control your impulses. This part of the brain is still growing and developing connections well into your adult years. So for young adults and teenagers, the decision-making center of the brain is not completely formed yet.At the same time, the teenage brain is also experiencing growth in another part of the brainthe amygdala (a-mig-dala). This part of the brain is responsible for emotions. Specifically, the amygdala talks to other parts of the brain about events related to rewards and fear.In essence, our emotional brains are having growing spurts and our impulses are out of control at the same time our cerebral cortexes are not finished growing. We simply don't have the tools to control those emotions and impulses. As a result, teenagers feel overly emotional and wishy-washy when it comes to decisions. This development cycle is one reason society doesn't consider children to be adults until after they are 18. Biologically, the teenage brain is not generally ready for adult decisions.So the differences between those who seem to make good decisions and those who seem to make bad ones may be fewer than you think. In fact, if you study the people you think make only good decisions, you will likely find they also make some catastrophically bad ones as well. A person's ability to make a good decision increases with age and experience though we all develop at different rates. While you are young, you may want to take advantage of those around you with bigger cerebral cortexes: adults. Their advice may be just what is needed to counter your amygdala.Which line from the text most clearly explains the main point of the introductory paragraph?
