Is neon transparent translucent or opaque
Neon is transparent opaque as it is light, colorless and order less inert noble gas.
What are noble gas?Noble gas are defined as the element that belong to group 18 of the modern periodic table.
It is also known as inert gas or aerogene.
Noble gas are light, transparent, colorless and order less gases.
They are the group of six inert or non reactive gases.
Noble gases are odorless, colorless, nonflammable gases with negligible chemical reactivity.
Noble gases are exceedingly stable and unlikely to form chemical bonds due to their complete valence electron shells, which have no tendency to add or lose electrons.
Noble gas were originally classified as group 0 in the periodic table because it was thought they had a valence of zero, which means their atoms could not mix with those of other elements to form compounds.
Thus, Neon is transparent opaque as it is light, colorless and order less inert noble gas.

Answer:
67 kg = 67 kg × 1×10⁶ mg / 1 kg
67 kg = 6.7×10⁷ mg.
Explanation:
The following data were obtained from the question:
Mass in Kg = 67 kg
Mass in mg =.?
Thus, we can obtain the mass in milligrams (mg) as follow:
1 kg = 1×10⁶ mg
Therefore,
67 kg = 67 kg × 1×10⁶ mg / 1 kg
67 kg = 6.7×10⁷ mg
Therefore, 67 kg is equivalent to 6.7×10⁷ mg

What is the molecular geometry of PBr3? A. trigonal pyramidal B. trigonal planar C. linear D....
The geometry of PBr₃ is trigonal pyramidal. Therefore, option A is correct.
Trigonal pyramidal geometry refers to the molecular geometry around a central atom in a molecule or ion where there are three bonded atoms and one lone pair of electrons. This geometry is commonly found in molecules with a central atom surrounded by three bonding pairs and one non-bonding pair of electrons.
The term "trigonal" refers to the arrangement of the three bonding pairs, which are positioned in a flat, triangular shape around the central atom. The term "pyramidal" indicates that the lone pair of electrons occupies the fourth position, giving the molecule a three-dimensional pyramid-like shape.

Using dimensional analysis How many mg are there in 8.75 X 107 kilograms?
Conversion factors:
[1000 g = 1 Kg]
[1000 mg = 1 g]
Can you please show the work
Answer:
8.75×10¹³ mg
Explanation:
From the question given above, we obtained:
Mass (in Kg) = 8.75×10⁷ Kg
Mass (in mg) =?
Next, we shall convert 8.75×10⁷ Kg to grams (g). This can be obtained as follow:
1 Kg = 1000 g
Therefore,
8.75×10⁷ Kg = 8.75×10⁷ Kg × 1000 g/1 kg
8.75×10⁷ Kg = 8.75×10¹⁰ g
Therefore, 8.75×10⁷ Kg is equivalent to 8.75×10¹⁰ g.
Finally, we shall convert 8.75×10¹⁰ g to mg. This can be obtained as illustrated below:
1 g = 1000 mg
Therefore,
8.75×10¹⁰ g = 8.75×10¹⁰ g × 1000 mg/ 1 g
8.75×10¹⁰ g = 8.75×10¹³ mg
Thus, 8.75×10⁷ Kg is equivalent to 8.75×10¹³ mg.

How does increasing the mass affect the kinetic and potential energy of a pendulum?
Explanation:
Anytime matter is in motion it has kinetic energy. The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has.
Both the kinetic energy and potential energy are directly proportional to the mass of the object. Hence, increasing the mass will increase the kinetic and potential energy of the pendulum.
What is kinetic energy ?The kinetic energy of an object is generated by virtue of its motion. Whereas, the potential energy is generated by virtue of its position. hen the object is at rest, the energy is stored in it in the form of potential energy. When the object starts moving, its potential energy starts to converts to kinetic energy.
The kinetic energy of an object is related to its mass and velocity by the equation:
Ke = 1/2 mv²
Potential energy P = mgh
where, g is the acceleration due to gravity and h is the height of the object from the surface.
Hence, both potential energy and kinetic energy are directly proportional to the mass of the object. An increase in mass increase both form of energy of the object.
Therefore, the kinetic and potential energy of the pendulum increases with mass.

Calculate the volume of a liquid with a density of 5.35 g/mL and a mass of 62.0 g.
Answer to the proper significant figures and include the proper unit.
My answer was 11.6 mL, but it was wrong.
Answer:
V= 12mL
Explanation:
you had the right idea with your Significant figures however, when we divide we see that it requires 2 significant figures as our least amount. this is because when looking at our division, 62 has 2 sig. fig. while 5.35 has a total 3. when looking at your answer we see that you had a total of 3 sig. figures. so in actuakity you had to round up to 12 and not to the tenths because the decimal makes .6 count as your third sig fig.

PLEASE HELP ASAP ONLY HAVE 10 MINUTES. A certain photon of light has a wavelength of 422 x 10 -9 m. What is the frequency of the light? Show work
Answer:
7.11 x [tex]10^{14}[/tex] Hz
Explanation:
The equation for converting wavelength to frequency is ν=c/λ, or the speed of light over wavelength. The speed of light is 3.00 x [tex]10^{8}[/tex], and our wavelength here is 422 x [tex]10^{-9}[/tex]. All we have to do now is substitute our given values:
