You are using a calorimeter to calculate the specific heat capacity of a metallic ore. The calorimeter contains 0.50 kilograms of water at room temperature (22 °C). We heat the ore in boiling water and then drop the metal into the calorimeter and wait for the water and metal to reach the same temperature. The mass of the ore is 3.5 kilograms. We find that the water has increased in temperature to 24.3 °C. Recall that the specific heat of water is 4.18 J/g–°C. Calculate the specific heat capacity of the ore.

Answers

the specific heat capacity of the ore : 0.018 J/g°C  Further explanation

In the calorimeter, the heat received is the same as the heat released  

Q abs = Q release

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

Q released by a metallic ore and absorbed by water at calorimeter

Q ore = Q water

Q water

m = 0.5 kg = 500 g

c = 4.18 J/g–°C.

Δt = 24.3 - 22 = 2.3

[tex]\tt Q=m.c.\Delta t\\\\Q=500\times 4.18\times 2.3=4807~J[/tex]

the specific heat capacity of the ore.

Q ore = Q water = 4807 J

m ore = 3.5 kg = 3500 g

Δt = 100 - 24.3 = 75.7

[tex]\tt 4807=3500\times c\times 75.7\\\\c=0.018~J/g^oC[/tex]

equatinal by elimination melha
8n-3y = 18 and5x+6y=27

Answers

Answer:

x = 3 and y= 2

Explanation:

Given equations:

           8x - 3y  = 18  - ---- (I)

           5x + 6y = 27 -------(II)

Solve this problem by elimination;

  In the elimination method, we simply find a common term that can make one of the variables in the two equation the same. Then we either add or subtract to remove the variable.

 Mulitply equation (i) by 5 to give equation III

 Mulitply equation (II) by 8 to give equation IV

     5(8x - 3y) = 5(18) ------- III

     8(5x + 6y) = 8(27) ------- IV

   40x - 15y = 90------- III

   40x + 48y = 216  ------- IV

Subtract  equation III and IV;

        -15y - 48y = 90 - 216

         - 63y = -126

                y = 2

Solve for x;

      40x - 15y = 90;

       40x - 15(2) = 90

         40x - 30 = 90

           40x = 90 + 30

              40x = 120

                 x = 3

use the Kinetic Theory to explain the following. when you come home from school and open the door you can smell your tea being cooked ​

Answers

Answer:

Tea is getting hot on the stove.  

2) As the tea and water gets hot, some combined molecules of tea and water will escape from the teapot.  

3) Those escaped molecules now have the entire free space of the entire room to float around in, which they do (because they have high kinetic energy due to being heated).  

4) Hence, in this scenario, your nose will detect a few of those molecules and you smell hot or warm tea.  

5) Cold tea would be a different story. Cold beverages like cold tea do not have the kinetic energy where molecules can 'break free' of the surrounding container. Someone could be sitting in the room having a can or bottle of cold tea and you would not notice that when you walked in the door.

would it float or sink?

Answers

Answer: It will sink

Explanation:

To solve this we must be knowing each and every concept related to carbon monoxide. Therefore, carbon monoxide float to the top of the room.

What is carbon monoxide?

When the carbon in fuels burns inefficiently, a toxic gas known as carbon monoxide is created. It is emitted both naturally—from forest fires or volcanic eruptions, for example—and artificially—through procedures. It is lighter than the air.

By attaching to and removing oxygen from myoglobin, carbon monoxide reduces the oxygen storage capacity in muscle cells, which is another way it upsets the body's processes. If carbon monoxide (CO) leaked into your home, carbon monoxide float to the top of the room. Numerous manufacturing and medicinal items employ carbon monoxide.

Therefore, carbon monoxide float to the top of the room.

What is tetanus? What are the symptoms and consequences of the disease? Who is at risk of developing tetanus? How do vaccines work? What is the history of the tetanus vaccine? Who should receive the tetanus vaccine? When should people receive the tetanus vaccine? Why is this schedule important? Has there been a change in tetanus incidence in the United States since the vaccine became available? What are the risks of vaccination versus non-vaccination? Do the risks outweigh the benefits? Are there areas in the world in which tetanus is prevalent? If so, does this affect the recommendations for US vaccination?

Answers

Answer:

The tetanus vaccine is a dose of the bacterium Clostridium Tetani, in inactive form or even a surface molecule that helps the body to actively form the antibody.

The tetanus vaccine has coverage for life, it is mandatory in those countries where the disease became common, such as the USA, Argentina, Chile, Uruguay among others.

Before a surgical act or a suspicion of exposure with this bacterium, the booster of the tetanus vaccine should be administered quickly.

Explanation:

Tetanus disease generates a tetanization of all the muscles of the organism, generating spasmodic contractions, which make it impossible to function and develop life when it affects the diaphragm as it makes breathing impossible.

Tetanization does not affect differently in age or sex, it only consists of contamination with the bacteria to be sufficient.

The sources of contagion are areas of mud or earth, rusty cutting or sharp elements, and poorly hygienic or abandoned areas. In order for the bacteria to be transmitted or the transmission route to be fulfilled, there must be a lesion of loss of continuity of the epithelium or mucosa.

It is incorrect because it should have a total of eight electrons with two electrons between each H and O

Further explanation

Lewis structure shows the form of bonds that occur in the valence electrons of an element or compound

This bonding usually occurs in covalent bonds

Valence electrons are electrons used in a chemical bond

The main group elements usually have valence electron configurations in the ns and np subshells, While the transition elements in the subshells (n-1) d and ns.

Element O has 6 valence electrons

Element H has 1 valence electron

To achieve stability, the element O needs 2 more electrons which are obtained from 2 electrons from the H element, while the H element needs 1 electron to be stable

B. A few positive particles bounced back because they were pushed away from the positive center.

Explanation:

The result of the experiment conducted by Rutherford shows that a few positive particles bounced back because they were pushed away from the positive center.

This is the central theme of Rutherford's experiment on a thin gold foil.

In 1911, Rutherford performed the gold foil experiment that gave the modeling of the atomic structure a great boost. He bombarded a thin gold foil with alpha particles. He discovered that most of the alpha particles passed through the foil while a few of them were deflected back. This led him to postulate that an atom has a small positively charged center where nearly all the mass is concentrated.

The relative atomic mass of element A : 6.075 u

Further explanation

The elements in nature have several types of isotopes

Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.

Atomic mass is the average atomic mass of all its isotopes

Mass atom X = mass isotope 1 . % + mass isotope 2.% ...

Element A

mass number of isotope 1 = 6 , percent : 92.5%

Consider a 5.430 g mixture of FeO and Fe3O4. You react this mixture with excess of oxygen to form 5.779 g Fe2O3. Calculate the percent mass of FeO in the original mixture.​

Answers

Answer:

Explanation:

A 5.430 g mixture of FeO and Fe3O4 is reacted with excess of oxygen to form 5.779 g Fe2O3. Find the masses of FeO and Fe3O4 present in the mixture.

I found the answer by doing the following:

Fe2O3 = 159.69 g/mol

FeO = 71.745 g/mol

Fe3O4 = 231.535 g/mol

5.779 g Fe2O3 / 159.69 g/mol = 0.03619 mol Fe2O3

x + y :rarrow: 0.03619 mol Fe2O3, where x = FeO and y = Fe3O4.

This implies that y = 0.03619 - x.

5.430 g = x*71.745 g/mol + (0.03619 - x)*231.535g/mol

x = 0.01846 mol * 71.745 g/mol = 1.324 g FeO

y = 0.03619 - 0.01846 = 0.01773 mol * 231.535 g/mol = 4.105 g Fe3O4

My question is why doesn't the following work:

4FeO + O2 :rarrow: 2Fe2O3

4Fe3O4 + O2  :rarrow: 6Fe2O3

_______________________

2FeO + 2Fe3O4 + O2 :rarrow: 4Fe2O3

5.779 g Fe2O3 / 159.69 g/mol = 0.03619 mol Fe2O3

Product:reactants in question are in a 2:1 ratio as given by the stoichiometric coefficients.

0.03619 mol / 2 = 0.01810 mol of FeO and 0.01810 mol Fe3O4.

0.01810 mol FeO * 71.745 g/mol = 1.299 g FeO

0.01810 mol Fe3O4 * 231.535 g/mol = 4.191 g Fe3O4

Obviously this doesn't work because the original mixture is 5.430 g and not 1.299 g + 4.191 g = 5.490 g. Why doesn't this work the way I think it should? Thank you.

Oil Silver Coal Uranium In the 1800s, the United States was still a very young nation, trying to solidify its identity. The Industrial Revolution began in Great Britain, a fast development of society following the introduction of machines. The United States was slower than Great Britain to fully embrace the changes. Yet key technological developments caused a rapid growth in American urban areas. Better farming methods and tools in the 1800s increased food production. Americans were able to grow enough food for their families as well as to sell. The abundance caused food prices to fall. The expansion of cotton and the growth of textile factories in northern states helped produce the first wave of American industry. More people turned to work in northern factories as a way to support their families. Thousands of immigrants to the United States also settled in or near port cities, looking for work. Even today, the need for work is a common reason people move to urban areas. As a result, cities grew in numbers of people and physical space. As more people and businesses moved in, they needed buildings for living and working. They needed ways to move around the city. We call this process urbanization. In 1820, the United States had only a few cities of 10,000 residents or more. About seven percent of U.S. residents lived in urban areas. The number of cities with more than 10,000 people grew quickly over the next 40 years, especially in the Northeast and Midwest. By 1860, about 20 percent lived in cities. Philadelphia and New York City were the most populated cities in 1860 and would soon reach one million residents. The urbanization of the United States quickened due to technology improvements. Without innovations in food production, the factories could not have grown so quickly. The trend quickened after 1860 and continued throughout the 21st century as well. By 2007, more Americans lived in or near cities than they did in rural areas. Select a sentence from the body of this article that can be removed without affecting the author's explanation.
