Now build the complete circuit. Connect a wire to each end of the pair of batteries. Then add the lightbulb and the switch, using additional wires as needed. To disconnect two parts, click where they’re joined, and then click Split Junction. You can also click Reset All to start over. You’ll be successful when you can close the switch (click, hold, and drag it) and the lightbulb glows. Use the drawing tool to sketch the parts of your successful circuit.

Electrons contribute greatly to the atom's charge, as each electron has a negative charge equal to the positive charge of a proton. Scientists define these charges as “+1” and “-1. ” In an uncharged, neutral atom, the number of electrons orbiting the nucleus is equal to the number of protons inside the nucleus.:

The moles of iron(III) oxide are :

- 4 moles

Given:

           moles of Fe (iron) = ?

           moles of Oxygen (O₂) = 3.0 moles

Reaction :

            4Fe + 3O₂ -------->  2Fe₂O₃

           4Fe  + 3O₂ ----------> 2Fe₂O₃

           4 mole +3 mole

Unity formula:

                    4 mole of iron (Fe) ≅ 3 moles of oxygen (O₂)

                    ??mole of iron (Fe) ≅ 3.0  moles of oxygen (O₂)

Cross multiplication:

                 moles of iron (Fe) =  3.0 moles *4 mole/ 3 moles

                 moles of iron (Fe) = 4 moles

moles of iron(III) is 4 moles produced from 3.0 moles of oxygen.

Answer:Poking a metal rod into an electrical socket.

Explanation:

It is because metal rod can conduct electricity easily. So while poking, the metal rod will conduct electricity and you will get an electrical shock.

Answer:

Steam thus released transforms heat energy from burning coal into mechanical energy that in turn spins the turbine engine. The kinetic energy of the spinning turbine does work in a generator and then the generator that turns this work into electric energy.

Explanation:

Power plants burn coal to produce electricity. The energy released from coal being burned is used to change water into steam. Steam thus released transforms heat energy from burning coal into mechanical energy that in turn spins the turbine engine. The kinetic energy of the spinning turbine does work in a generator and then the generator that turns this work into electric energy.

Determine the resultant velocity for the plane when it is travelling

i) To the east

ii) To the west

answer :i)  270 i

             ii)  -150 i

Explanation:

velocity of Airplane = 210 m/s

wind velocity = 60 m/s to the east

The resultant velocity for the plane when it is travelling  

let the velocity of the wind = V2

           velocity of the plane = v1

i) The resultant velocity for the plane when travelling to the east

Vr = V2 i  + V1 i

Vr= 60i + 210i  = 270i

ii) resultant velocity when the plane is travelling to the west

Vr = - V1 i + V2i

     = -210i  + 60 i = -150 i  

Answer:

P1*V1/T1=P2*V2/T2

Answer:

Metals react by losing electrons.  So, there is high reactivity due to lower attraction. Non-metals react by gaining electrons. So, there is high reactivity due to higher attraction.

Explanation:

Metals react by losing electrons. So, there is high reactivity due to lower attraction. Non-metals react by gaining electrons. So, there is high reactivity due to higher attraction. Also, electrons lost by metals transfer to the nonmetals. It is easier for the metals to lose their valance electrons and form cations rather than gaining electrons.

Metals do not hold on to or attract electrons while nonmetals hold on to or attract electrons.

In the periodic table, metals are found towards the left hand side of the table while nonmetals are found towards the right hand side of the table.

Electron affinity of elements increase from left to right across the period. Electron affinity refers to the ability of elements to attract or hold electrons. This ability increase steadily across the period.

Usually, the electron affinity values of nonmetals are very high showing that they easily hold on to and attract electrons while the electron affinity values of metals is very low showing that they do not easily hold on to and attract electrons.

Answer:

B

Explanation:

Conductors are able to conduct electricity and temperature. Most of the metals, metalloids and alloys are conducting. Like iron (Fe) nickel is a good conductor.

Conductivity is a physical property of substances indicates the ability to conduct heat and electricity. Substances like metals are conductors because of the presence of free electrons in them.

The flow of free electrons in solids make the substance conducting. Substances which does not conduct is called insulators and those which conduct partially is called semiconductors.

Gases and liquids with fewer electrons are not conducting. Thus bromine is not a conductor. Krypton is a noble gas and is not conducting, potassium does not conduct electricity but it is thermally conducting.

Hence nickel (Ni) is the element having similar conductivity of iron. Thus option B is correct.

They are products because they are present after the reaction.

Explanation:

A chemical reaction refers to any interaction between two or more chemical species that leads to the formation of new chemical species. The species that interacted with each other are called reactants. They were present before the reaction commenced. The species that were formed after the interaction are called products. They only appear after the reaction.

In cellular respiration, carbon dioxide and water appear after the chemical reactions that take place, hence they are products.

Answer:

Amount left after 140 days is 38.125 g.

Explanation:

Given data:

Half life of Co-59 = 35 days

Total mass of sample = 610.0 g

Sample remain after 140 days = ?

Solution:

Number of half lives passes during 140 days:

Number of half lives  = T elapsed / Half lives

Number of half lives  = 140 days / 35 days

Number of half lives  = 4

Amount left:

At time zero = 610 g

At first half life = 610 g/2 = 305 g

At second half life = 305 g/2 = 152.5 g

At 3rd half life = 152.5 g/2 = 76.25 g

At 4th half life = 76.25 g /2 =38.125 g

Amount left after 140 days is 38.125 g.

Answer:

I believe the boiling point is 102 degrees Celsius and the freezing point is -2 degrees Celsius (so C).

Explanation:

Gas has a higher entropy than liquid, who has a higher entropy than solid. If a solid melts or a liquid vaporizes, the entropy increases. If a solute is present, it also contributes to the entropy of the mixture. The liquid already has a higher entropy (molecule randomness or disorder) than the pure liquid, so there's less likelihood of forming gas. This, therefore, means that it has a higher boiling point. This randomness also opposes freezing. A lower temperature has to reached before balance between solid and solution reached. So, the freezing point is lower.
