If an object has a mass of 180 g and a density of 6 g/cm^3, what is the volume of the object?

Answers

Answer:

The answer is 30 cm³

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

[tex]volume = \frac{mass}{density} \\[/tex]

From the question

mass = 180 g

density = 6 g/cm³

We have

[tex]volume = \frac{180}{6} \\ [/tex]

We have the final answer as

30 cm³

Which of the following best describes how Thomson
concluded that electrons are present in all atoms.
a
The charge-to-mass ratio of electrons is always the
same constant, no matter which substances are
used in the cathode ray tube.
b The cathode ray was able to turn a wheel.
The cathode ray always bent toward a negatively
charged plate.
d
The charge-to-mass ratio is unique to each different
element.

Answers

Answer: A

Explanation:

The charge-to-mass ratio of electrons is always the same constant, no matter which substances are used in the cathode ray tube.

Explanation:

Thomson in his model of atom discussed that the atom consists of a negative charge particle termed electron randomly distributed in the positively charged sphere to balance the negative charge.His model of the atom was also known as the Plum pudding model of the atom. In which electrons are embedded in positive soup.He discovered electrons by conducting an experiment with cathode rays in which cathode rays emerging from the cathode were observed to be deflected towards the positively charged plate.He also conducted the same experiment with different metals (for anode and cathode) and gases and found out that the charge to mass ratio of the electron was regardless of the metals or gases used in the experiment.With this, he landed on the conclusion that these particles of cathode rays are the universal component of matter.

So, from this, we can conclude that the charge-to-mass ratio of electrons is always the same constant, no matter which substances are used in the cathode ray tube describes Thomson's conclusion that electrons are present in all atoms.

Why are the coefficients before a chemical symbol important?​F. ​ They show the number of elements in each molecule.​G. ​ They indicate the number of molecules of each substance.​H. ​ They describe the number of times each molecule reacts.​J. ​ They explain the order in which the reaction takes place

Answers

Answer:They indicate the number of molecules of each substance

Explanation:

When we write chemical reaction equations, we usually put a number before the symbol of each reactant.

These coefficient shows the number of molecules of that specie that is involved in the balanced reaction equation for the reaction.

These coefficients are important because they are used in carrying out stoichiometric calculations.

For example 99.98% of all Hydrogen in the universe is [tex]^1H[/tex] meaning hydrogen with 1 proton and 0 neutrons while the remaining 0.02% is  [tex]^2H[/tex] meaning that [tex]^1H[/tex] is the most abundant by  percent.

32 N of Force. 37 N force. How strong is the net force and in which direction?

Answers

5 units to the left.

Explanation:
They are working against each other. That means you subtract.

32 - 37 = -5

You are moving 5 units to the left because 37 is negative which means it is moving left. The key word is left. In physics, you would get the same answer if you did it this way.

37 - 32 = 5

The 5 moves in the same direction as the 37

Which electron configuration represents the electrons in an atom of sulfur in an excited state? 2 – 8 – 6
2 – 7 – 7
2 – 8 – 7
2 – 7 – 8

Answers

The relations of the quantum numbers allow to find that the correct answer for the configuration of the excited state is:

  2 - 7 - 7

The electronic configuration of the elements is the distribution of electrons and different levels and sublevels fulfilling the relationships between quantum numbers.  

The principal quantum number (n) goes from 0 to infinity The orbital quantum number (l) goes from 0 to n-1, in general it is represented by lera s, p, d, f The magnetic quantum number ([tex]m_l[/tex]) ranges from -l to l The spin quantum number ([tex]m_s[/tex]) can have two values ​​+ ½ and - ½

In the base configuration Sulfur of the periodic table is 2 - 8 - 6

This is at the lowest energy configuration, when the atom acquires energy, an electron from its shell must be promoted to the next level.

                       

That is, an electron from level n = 2 that is full is promoted to level n = 3 since in this shell there is still room for two electrons, the configuration of the excited state is:

                  2- 7 - 7

Let's examine the different alternatives:

1) 2 - 8 -6

False, this is the configuration of the base state

2) 2 - 7 - 7

True. An electron is promoted to the next level due to the excitation of the atom

3) 2 - 8 -7

False, in this configuration the atom becomes an ion

4) 2 - 7 - 8

False, there is an electron transfer between two levels, but there is an extra electron that turns that atom into an ion

In conclusion using the relationships of quantum numbers we can find that the correct answer for the excited state configuration is:

2 - 7 - 7

Water can undergo a change of state when its energy changes at specific temperatures. Solid water, or ice, changes into liquid water when its energy increases at its melting point. a. Describe this process. b. Explain how the energy changes with each state.

Answers

Answer: The solid turns into liquid during melting.

Explanation:

a. The process of a solid turning into liquid is called melting. The solid ice turns into a liquid during the melting process. The solid molecules gain energy and flow as a liquid.

b. The energy of the molecules increases in the liquid state. When the ice turns into a liquid the energy of the molecules increases. The application of heat or excess temperature increases the energy of the molecules.

gives a student a quarter which has been pre-weighed as 5.6026 g. The weight that the
student obtains for the same quarter is 5.6013 g. What is the percent error in the
students reading?

Answers

Answer:

The percent error is 0.023%.

Explanation:

Pre-weighed of a quarter is 5.6026 g.

The weight that the  student obtains for the same quarter is 5.6013 g.

We need to find the percent error in the students reading. It is given by the formula as follows :

[tex]\%=\dfrac{|\text{original value-calculated value}|}{\text{original value}}\times 100[/tex]

Putting all the values, we get :

[tex]\%=\dfrac{5.6026 -5.6013 }{5.6026 }\times 100\\\\\%=0.023\%[/tex]

So, the percent error is 0.023%.

Where do rivers usually begin?

at the ocean
at groundwater outlets
in mountainous regions
in lakes and larger rivers

Answers

Answer:

in mountainous regions

Explanation:

The rivers usually begins in mountainous regions. A river's source is typically located in a high area, such a mountain or a hill. A river may have several sources. Some rivers start where an underground natural spring discharges water.

What is a mountain ?

A mountain is an elevated area of the crust of the Earth, typically with steep sides that reveal a substantial amount of bedrock that has been exposed.

Although definitions vary, a mountain is often taller than a hill, rising normally at least 300 meters above the surrounding terrain, and differs from a plateau in having a constrained peak region.

Every river has a beginning place where the water flow starts. We refer to this source as a headwater. Some rivers have their beginnings in hills or mountains, where rainwater or snowmelt gathers and creates little channels.

It is possible for the headwater to originate from mountain snowmelt or rainfall, but it is also possible for it to bubble up from the ground or develop at the edge of a lake or big pond.

Thus, option C is correct.

What is the mass of 4.49 x 10º carbon dioxide, CO2, molecules?

Answers

To find this you have to find the molar mass of CO2 which you can get on the periodic table, 12 + 16 + 16 = 44 g/mol

4.49 x 10^0 / 44 g/mol = .1020 mol CO2

1 mol = 6.022 x 10^23 molecules (avogadros number)

so .1020 mol x 6.022 x 10^23 =
6.14 x 10 ^22 molecules CO2
