How does knowing the meaning of prefix-trans help you remember what happens to light that strikes a translucent object ?
Explanation:
The prefix trans- and its variant tra- mean "across".
A translucent substance allows some light to go "across" it to the other side. Also, think about a transparent substance: it allows light to go "across" it; or a translation, it is a going "across" from one language into another.

What element is represented by the ground state electron configuration shown above?
Answer:
Pd (palladium).
Explanation:
46 electrons total, this is representative of the Pd (palladium) element.
Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Palladium (Pd) element is represented by the ground state electronic configuration.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
The ground state electronic configuration of 1s² 2s² 2p⁶3s² 3p⁶4s² 3d¹⁰ 4p⁶ 5s² 4d⁸ shows total 46 electrons. The element with atomic number 46 is palladium, Pd. Palladium is a d block element. Palladium is found in group 8 and period four of periodic table.

List all the layers of the atmosphere and give one SENTENCE description or characteristic for each layers.
Answer:
Troposphere, stratosphere, mesosphere, and thermosphere.
Explanation:
Troposphere - It is the lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere.
Stratosphere - It is the layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere).
Mesosphere - It is the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.
Thermosphere - It is the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. The thermosphere is characterized throughout by an increase in temperature with height.
Answer:
The First layer is the troposphere. The troposphere is what we live in. It creates weather for us. Second layer is the Stratosphere. You will find the ozone layer in it. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn't be possible without this layer of protection. Third layer is Mesosphere. The Mesosphere is very important for earth's protection. The mesosphere burns up most meteors and asteroids before they are able to reach the earth's surface. Fourth layer is Thermosphere. The Thermosphere absorbs the sun radiation making it very hot.
Explanation:: I don't know if you include this one but the fifth layer is the Exosphere. Although the exosphere is the most distance layer of earth's atmosphere it is the layer that is the planet's first line of defense against the sun's rays. It is also the first layer to come into contact and protect the earth from meteors, asteroids, and cosmic rays.

What is the molecule that formed between B and F?
Answer:
BF3
Explanation:
For this question, you need to use the number of valence electrons present in each element. Boron is in group 3/13 on the periodic table so you know it has 3 valence electrons while Fluorine is in group 7/17 so it has 7 valence electrons. These elements are both covalent so they will share electrons. All elements in the first three rows want to reach either have 8 valence electrons or zero valence electrons depending on whichever is easier. When B and F interact each Fluorine will only want to take one electron, but Boron wants to get rid of all 3 electrons, so it will bond with 3 Fluorine to get rid of all its valence electrons.

On a .75-meter table sits a book whose mass is .5 kilograms. How
much Potential energy does it have?
Answer:
P.E = 3.675 J
Explanation:
Given data:
Height of table = 0.75 m
Mass of book = 0.5 kg
Potential energy = ?
Solution:
Formula:
P.E = mgh
g =acceleration due to gravity = 9.8 m/s²
by putting values,
P.E = 0.5 kg× 9.8 m/s² ×0.75 m
P.E = 3.675 kgm²/s²
J = kgm²/s²
P.E = 3.675 J
Answer:
[tex]\boxed {\boxed {\sf 3.675 \ Joules}}[/tex]
Explanation:
Gravitational potential energy can be found using the following formula.
[tex]E_p=m*g*h[/tex]
Where m is the mass, g is the gravitational acceleration, and h is the height.
The mass of the book is 0.5 kilograms. The acceleration due to gravity on Earth is 9.8 m/s². The height of the book is 0.75 meters.
[tex]m= 0.5 \ kg \\g= 9.8 \ m/s^2 \\h= 0.75 \ m[/tex]
Substitute the values into the formula.
[tex]E_p=(0.5 \ kg)(9.8 \ m/s^2)(0.75 \ m)[/tex]
Multiply.
[tex]E_p=(4.9 \ kg*m/s^2)(0.75 \ m)[/tex]
1 kg*m/s²= 1 Newton[tex]E_p=(4.9 \ N)(0.75 \ m)[/tex]
[tex]E_p=3.675 \ N*m[/tex]
1 N*m= 1 Joule[tex]E_p=3.675 \ J[/tex]
The book has 3.675 Joules of gravitational potential energy.

How many H2O molecules are in 2 mol
Answer:
A mole of horses would be Avogadro number of horses (a lot actually !). Avogadro number is 6.023 x 10(23). A mole of H (hydrogen) atoms contains 6.023 x 10(23) H atoms. A mole of H2 molecules contains 6.023 x 10(23) H2 molecules or 2 moles of H atoms (since each molecules has 2 atoms).
Explanation:
Answer:
A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance. The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.

1. What three characteristics determine the type of sedimentary rock?
Answer:
Characteristics of Sedimentary Rocks. ● The color of the sedimentary rock is determined by the content of the strata that were pressed together to form it. If the layers have a high organic content, the rock is usually gray to black in color. On the other hand, high amount of minerals give the rock the color of the mineral.

What do the colors on the periodic table show?
A. which element it is
B. the metallic properties of the element
C. the types of compounds the element can make
D. whether the element is a solid, a liquid, or a gas at room temperature
Answer:
Periodic tables can use color to identify other element characteristics. For example, an electronegativity periodic table color codes the elements based on how electronegative they are. The valence periodic table uses color to identify the most common valence state for each element.Oct 2, 2019
pls like and rate us .
The color given to a the elements in periodic table is to characteristics of the elements mainly to identify whether they are solid, gas or liquid. Thus option D is correct.
What is periodic table?A periodic table contains all the discovered elements which are classified into different groups and periods. Groups are vertical columns of elements with similar properties and same number of valence electrons.
Periods are horizontal rows from left to right with an increase in atomic number. There are 18 groups and 7 periods in periodic table. Each group has given each color and some elements showing exceptional characteristics such as hydrogen and helium have separate colors.
All the first group elements called alkali metals have one color and the second groups elements with another color, All the d-block elements are given the same colour and metals in p-block elements have the same color.
Similarly, all the metalloids have one color and all other gases have the same colour in which inert gas group and halogen group have seperate colours.
Hence, the color in periodic table helps to identify the element's nature like its state also. Thus option D is correct.
