Answer:

The limiting reactant is the covers.

We are left with 3750 sheets of lined paper, 1125 sheets of graph paper and 25 staples.

Explanation:

the reaction is:

B - book

C - cover

Sl = sheet of lined paper

Sg - sheet of graph paper

St - staple

1B = 2C + 50Sl + 25Sg + 3St

We have covers for 150/2 = 75 books

We have lined paper for 7500/50 = 150 books

We have graph paper for 3000/25 = 120books

We have Staples for 250/3 = 83.(3) books, so for 83 books as we cannot make 1/3 of a book.

Because we only have covers for 75 books, covers are the limiting reactant.

After making 75 books we are left with:

0 covers

7500 - 75*50 = 3750 sheets of lined paper

3000 - 75*25 = 1125 sheets of graph paper

250 - 75*3 = 25 staples

Which change most likely occurs when the kinetic energy of water vapor decreases during condensation?

mylen [45]

Answer:

When the kinetic energy of water vapor decreases during condensation, <u>slowly moving particles near the cool surface condense.</u>

Explanation:

The change of state from a gas to a liquid is condensation. Liquid molecules which have this certain kinetic energy threshold escape from the surface and become vapor. As a result, the remaining liquid molecules now have lower kinetic energy. The temperature of the remaining liquid decreases as evaporation occurs.

The air that surrounded it cooled the cold can or glass. When you're cooling off .They lose kinetic energy, a gas. The particles move more slowly as they move, the attractions between them cause the formation of droplets of liquid. Condensed With, when hot air containing water vapor reaches water, water also forms. Cold surface touch, such as a glass of ice or soil that has a cold surface refrigerated throughout the night.

Cl2 + H2 + 2HCI

Cloud [144]

Answer:

1 and 2

Explanation:

The given equation is:

Cl₂ + H₂ → 2HCl

A coefficient is the variable or number before a chemical specie.

In this reaction Cl₂ and H₂ are the reactants;

The coefficient of Cl₂ is 1,

H₂ is 1,

HCl is 2

The subscript is the number to the lower power after a chemical specie is denoted.

For Cl₂, it is 2

Which conclusion could be made from Ernest Rutherford’s gold foil experiment ?

mote1985 [20]

From the Rutherford's gold foil experiment one can conclude that nucleus was very small in size, as compared to the atoms. In the experiment Rutherford discovered that, the atom contains a very small nucleus where all of its positive charge of the atom is present.

Two common uses for electromagnets are _____.

Novosadov [1.4K]

Two common uses for electromagnets are _producing strong magnetic fields_& __electrical switches_.

Explanation:

An electric current can turn a ferromagnetic material temporarily magnetic using Faraday's principle, if the wire carrying the current is wound in coils around the ferromagnetic material. When the electric current is turned on the ferromagnetic material, such as iron, becomes magnetic but loses the magnetism when the current is switched off. This application can be used in a junkyard where a crane with a ferromagnetic arm can lift scrap cars from one point and dump them is a scrapper.

An electromagnet switch can also be applied in the switching on and off of a larger current. These are called relay switches. When the smaller current is turn on, it magnetizes a ferromagnetic material. The magnet then attracts another metal that is attached to a contact arm of a switch. The attraction results in the closing of a switch of a larger current. When the smaller current is switched off, the loss of magnetism causes the metal with the contact arm to open the larger switch.
