Where exactly is an orbital? I understand they are a volume where we expect to find electrons 90% of the time but I don't understand where their shapes are and fit on an atom, and the different forms of orbitals confuse me a little. Can someone explain me where they are with the help of an image? Pardon me if my question isn't very clear

Answers

Answer 1

Answer:

95% of the time (or any other percentage you choose), the electron will be found within a fairly easily defined region of space quite close to the nucleus. Such a region of space is called an orbital. You can think of an orbital as being the region of space in which the electron lives

What is the mass of an object with a density of 5.7 g/cm^3 and a volume of 48
cm^3? *

Answers

Answer:

273.6 g

Explanation:

mass =(density)(volume)

mass=(5.7g/cm^3 )(48 cm^3)

cancel out your cm^3 and your are left with grams

multiply (5.7g)(48)=273.6 g

The mass of an object with a density of 5.7 g/cm³ and a volume of 48 cm³ is 273.6 grams.

What is density?

Density is defined as the degree to which a material is packed together.

It is also defined as a mass per unit volume of the substance.

Its SI unit is kilogram per cubic meter or  gram per meter.

Density can be expressed as

Density = mass / volume

Mass =  density x volume

As given, Density = 5.7 g/cm³

                Volume = 48 cm³

So, Mass =  5.7 g/cm³ x  48 cm³

               =  273.6 grams

Thus, the mass of an object with a density of 5.7 g/cm³ and a volume of 48 cm³ is 273.6 grams.

An echolocation refers to a method that relies on sound waves and is used by different animal species for navigation, communication, and finding food. Therefore, option A is correct.

What is an echolocation ?

Echolocation is a method used by bats, dolphins, and other animals to locate objects using reflected sound. This enables the animals to move around in complete darkness, allowing them to navigate, hunt, recognize friends and enemies, and avoid obstacles.

(1) To hunt for prey, bats make high-frequency sounds. (2) Sound waves are used by dolphins and other toothed whales to locate prey and navigate their surroundings. (3) Nocturnal oil birds use echolocation to navigate their surroundings, particularly in low-light conditions.

Echolocation is used to help with orientation, obstacle avoidance, food acquisition, and social interactions.

When many earthquakes are studied, there is another common pattern that emerges: a "Shadow Zone". This is an area, for any earthquake, on the Earth where direct S-waves don't arrive at all and P waves are refracted. What do you think causes these P waves to be refracted? *

Answers

Answer:

Sudden decrease in the velocity at the boundary.

Explanation:

The shadow zone is the zone of the earth from angular distances of 104° to 140° from a known earthquake that does not directly receive any P waves. Now, this shadow zone occurs as a result of S waves getting stopped completely by the liquid core and the P waves being refracted by the liquid core.

From earlier seismic discoveries, this boundary which is the shadow zone that does not directly receive any P-waves was found to be due to the fact that the P-waves were refracted inwards as a result of the sudden decrease in velocity at the boundary.

You have a solution of water and pure ethanol. The boiling point of water is 100 degrees Celsius and the boiling point of pure ethanol is 78 degrees Celsius. A. What process would you would use to separate this solution? Describe, in detail, how this process works.

Answers

Answer:

Distillation

Explanation:

A solution of water and ethanol are miscible. Hence, they can only be separated by a process known as distillation. Distillation is the process in which two or more constituents in a mixture are separated based on there difference in boiling points. The mixture is subjected to high heat and the one with the least boiling point distills/evaporates out first followed by the next least boiling point.

From the explanation above, it can be deduced that ethanol (with boiling point of 78°) will be distilled out while water remains in the boiling tube or container.

Answer in units of J.

Answers

Q must be supplied = 119523.3~J

Further explanation  

The law of conservation of energy can be applied to heat changes, i.e. the heat received/absorbed is the same as the heat released  

Q in = Q out  

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  

So from the question :

Q to the system(Q supplied) = Q water + Q steel vessel(Q gained)

[tex]\tt Q~supplied=m.c\Delta T(water)+m.c\Delta T(vessel)\\\\Q~supplied=375\times 4.18\times (100-35)+532\times 0.51(100-35)\\\\Q~supplied=101887.5+17635.8=119523.3~J[/tex]

Rubbing alcohol or isopropanol can be described by the chemical formula C3H7OH. One milliliter of isopropanol has a mass of 0.76 g, so its density is 0.76 g/mL. Isopropanol is often used as a cleaner or a disinfectant and evaporates when placed on warm objects. However, caution must be taken when using isopropanol, because it is also highly flammable. Which of the following is a chemical property of isopropanol?
A. One mL of isopropanol has a mass of 0.76 g.
B. Isopropanol has a density of 0.76 g/mL.

A chemical property of isopropanol : D. Isopropanol is flammable.

Further explanation

There are changes that occur in the mater: physical changes and chemical changes

Classification uses the principle of the initial and final state of the substance.

Physical changes do not form new substances, so the properties of the particles remain the same.(size,volume,shape)

Example : boiling and freezing, just change its phase form from liquid to gas or from liquid to solid

 

Chemical changes/reaction form new substances(products) that are different from the initial substances(reactants)

Example : toxic, corroded

So :

the physical properties of isopropanol :

mass, density, evaporation

the chemical properties of isopropanol :

highly flammable

Answer:

D. Isopropanol is flammable.

Explanation:

Mass, volume, temperature, phase of matter, color, texture, density, and hardness are all examples of physical properties. However, flammability is an example of a chemical property.

Chemical properties describe an object's potential to change its chemical composition. These properties depend on the types of atoms found in the object and the arrangement of those atoms (and their subatomic particles).

A balloon is a sphere with a radius of 5.0 m. The force of air against the walls of the balloon is 45 N. What is the air pressure inside the balloon? Surface area = 12.56 × radius² 1 Pa = 1 N/m² How would I solve this problem? What are the steps or a good way to remeber how to solve?

Answers

Answer:

0.127 N/m² or 0.127 Pa

Explanation:

From the question given above, the following data were obtained:

Radius (r) = 5 m

Force (F) = 40 N

Pressure (P) =.?

Next, we shall determine the Surface area of the sphere (i.e the balloon). This can be obtained as follow:

Surface area = 12.56 × r²

Radius (r) = 5 m

Surface area = 12.56 × 5²

Surface area = 12.56 × 25

Surface area = 314 m²

Finally, we shall determine the pressure as follow:

Force (F) = 40 N

Surface area = 314 m²

Pressure (P) =.?

Pressure = Force /Area

Pressure = 40/314

Pressure = 0.127 N/m² = 0.127 Pa

Therefore, the pressure inside the balloon is 0.127 N/m² or 0.127 Pa.

How does the valence electron configuration (entire last energy level configuration) relate to the group number on the Periodic Table? Use the shorthand notation in your discussion.

Answers

Answer:

The valence electron configuration determines the group to which an element belongs to.

Explanation:

The valence electron configuration of an atom of an element refers to the number of electrons in that atoms outermost shell.

The valence electron configuration is related to the group number of an element in that the number of electrons in the valence shell of an atom of an element determines the group to which an element belongs to. For example, all elements having one valence electron belong to group IA of the periodic table. Similarly, all elements having seven valence electrons belong to group VIIA of the periodic table.

This is because, since the reactivity of an element is related to its ability to either gain or lose a certain number of electrons in its valence shell, elements having same number of valence electrons have similar chemical properties.
