Answer:

1)Oxygen atoms have 8 electrons and the shell structure is 2.6. The ground state electron configuration of ground state gaseous neutral oxygen is [He]. 2s2. 2p4 and the term symbol is 3P2.

Explanation:

2)If the element were to become excited, the electron could occupy an infinite number of orbitals. However, in most texts the example will be the next available one. So for oxygen, it might look like this: 1s22s22p33s1 - where the valence electron now occupies the 3s orbital in an excited (i.e. not ground) state

Answer:

Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. It is a silvery-white, soft, non-magnetic and ductile metal in the boron group. ... Aluminium is remarkable for its low density and its ability to resist corrosion through the phenomenon of passivation.

From the calculation, the voltage of the electrolytic cell is -0.92 V

An electrolytic cell is is cell that produces energy by a nonspontaneous chemical process. The anode of this cell is zinc while the cathode is aluminum.

The voltage of the cell is obtained from Ecathode - E anode = -1.66 V - (-0.74 V) = -0.92 V

Answer:

n order to find the velocity of the moving object, you will need to divide the change in position by the change in time. Specify the direction moved, and you have the average velocity

Velocity of an object can be measured from the distance travelled by the object and the time taken to travel. Also we can find it from the kinetic energy of the object if known.

Velocity of an object is the rate of its speed. It is a physical quantity which measure the displacement occurred for an object within unit time  .Mathematically it is the  ratio of distance or displacement to the time.

Kinetic energy is generated in an object by virtue of its motion. It is directly proportional to the mass  m and square of the velocity v by the relation written below:

KE = 1/2 MV²

By this relation we can say that the velocity of an object is inversely proportional to the mass of the object. If mass increases velocity decreases. Lighter objects moves in  higher velocity.

Hence, we can know the velocity of an object by the distance and time of travel or movement of that object as well as from its kinetic energy.

Answer:

D. A compound can be separated into two or more elements through a chemical reaction.

Explanation:

By method of elimination, we are going t obtain the correct  option.

A. A compound is made up of a single atom.

This is wrong because, a compound can contain more than one atom.  An example is H2O

B. A compound is made up of many atoms that are all the same type.

This is wrong because a compound can contain atoms of different elements. An example is H2O. It contains atoms of hydrogen and oxygen.

C. A compound can be separated into two or more elements through physical processes.

This is wrong. H2O being a compound cannot be separated by ordinary physical means.

D. A compound can be separated into two or more elements through a chemical reaction.

This is the correct option.

Answer:

35 °C is the final temperature.

Comment if you need step to step explanation.

A 100.0 gram sample of water at 50.0°C is mixed with a 50.00 gram sample of water at 20.0°C. 35 °C is the final temperature of the 150.0 grams of water.

The physical concept of temperature indicates in numerical form how hot or cold something is. A thermometer is used to determine temperature. Thermometers are calibrated using a variety of temperature scales, which historically defined distinct reference points or thermometric substances.

The most popular scales are indeed the Celsius scale, sometimes known as centigrade, with the unit symbol °C, the Fahrenheit level (°F), as well as the Kelvin scale (K), with the latter being mostly used for scientific purposes. Among the seven units inside the International Units of Measure is the kelvin (SI).

Final temperature = (m₁×T₁×c₁  +  m₂×T₂×c₂)/( T₁+ T₂)

                            =  (100.0×50.0×4.18  +   50.00×20.0×4.18 )/( 50.0+ 20.0)

                           = 35 °C

Therefore,  35 °C is the final temperature of the 150.0 grams of water.

volume = final volume of water - initial volume of water

volume = 13.91 - 12 = 1.91 mL

Answer: acid rain

Explanation: Acid rain is one way in which rocks can be chemically weathered. It can harm forests and crops, damage bodies of water, and contribute to the damage of statues and buildings. In this activity you will simulate the chemical weathering of limestone, which is a soft, sedimentary rock that reacts easily to acid rain.

No, unless you're doing some sort of course where they demand that you do. It's useful to remember the general features of the periodic table (what each block is, where they are in relation to each other, roughly where the most common elements are), but memorizing the entire thing would simply be a mnemonic exercise

im just gonna explain how a speaker works and how it can make a window move. So a speaker has a crystal in it that when hit with and electric charge moves like a diaphragm that makes sound waves. the more electricity the slower it moves yet the slower it moves the bigger the movement. Anyway when that crystal moves it also moves the cardboard pice in front of it making a louder sound. The best way to think about it is a sound wave is like wind, its just moving air. so that moving air can push and pull something like a window pane. Cool Huh?

A strong chemical bond is formed from the transfer or sharing of electrons between atomic centers.

Answer:

Molecules in solids are tightly packed because the atoms are freezed together. Molecules in liquids are loosely packed because atoms are broken down and can move anywhere. Molecules in gases are free; the atoms can move or spread anywhere.

Solids do not move; hence no speed.

Liquids move and slide past past each other.

Gases move freely at high speeds
