calculate the wavelength of light in nm that has a the frequency of 1.24 × 10^15s –1 . The velocity of light is 3.00 × 10^8m/s.
Answer:
nose
Explanation:
Among electromagnetic waves, UV rays are most dangerous because exposure to these radiation cause serious problems in living organism. Therefore, the wavelength of light is 2.41×10⁻⁷m.
What is electromagnetic wave?Electromagnetic wave is a wave which contain two component one is electric component and other is magnetic component. The electric and magnetic component are perpendicular to each other. There are so many wave that comes under electromagnetic wave like infrared wave , radio wave, light wave.
There is a relation between frequency of wave, and wavelength of wave
Mathematically,
ν=c÷λ
where,
ν=frequency of light=1.24 x10¹⁵s⁻¹
c is speed of light that is 3×10⁸m/s
λ is the wavelength of light=?
Substituting all the values
1.24 x10¹⁵s⁻¹=3×10⁸m/s÷λ
λ= 2.41×10⁻⁷m
Therefore, the wavelength of light is 2.41×10⁻⁷m.

can barium ionically bond with kalium
Answer:
NO
Explanation:
Barium cannot ionically bond with Kalium. Kalium is the Latin name for potassium.
Both Barium and potassium are metals. Metals and Metals do not combine to form ionic compounds. Only metals and non-metals form this bond type.
The reason for this is that ionic bond forms by the transfer of electrons from one specie to another that receives it. Barium is metal and would freely donate electrons to attain stability. Kalium is metal and shares similar property.PLEASE HURRY I WILL GIVE BRAINLIEST ANSWER
Cation is the postively charged unit which is formed by the transfer of one or more electrons. It is attracted towards cathode thus it is called the CATION.
_____________________________________Question no 2:IONIC BOND:Ionic bond is the type of bond which is formed between the positive and negative ions. It is mostly formed between the Metals (i.e. group 1 and 2) and Non metals (i.e. mostly group 7). The positive charge on metal is due to the loosing of electron and negative charge on non metal is due to accepting the electron.
_____________________________________Question no 3:POLYATOMIC ION:A molecular ion is a covalently bonded set of two or more atoms, that can be considered to behave as a single unit, it also has a charge on it.
_____________________________________Question no 4:CONDUCTIVITY:Conductivity is more in liquid than in solid because the conductivity is flow of electron and the movement is less in solid than liquids thus the solid has less conductivity. The liquid has more movement of molecules due to which there is more conductivity.

*your answer should be written as X.X
2AlBr3 + 3CaO —> Al2O3 + 3CaBr2
Answer:
7.5 moles of CaBr2 are produced
Explanation:
Based on the equation:
2AlBr3 + 3CaO → Al2O3 + 3CaBr2
2 moles of AlBr3 produce 3 moles of CaBr2 if CaO is in excess.
Using this ratio: 2 moles AlBr3 / 3 moles CaBr2. 5 moles of AlBr3 produce:
5 moles AlBr3 * (3 moles CaBr2 / 2 moles AlBr3) =
7.5 moles of CaBr2 are produced

Compare and contrast the ways mitosis and meiosis are important to reproduction.
Answer:
The purpose of mitosis is cell regeneration, growth, and asexual reproduction,while the purpose of meiosis is the production of gametes for sexual reproduction. Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new daughter cells.
Explanation:
Mitosis produces two cells from one parent using one division event. But meiosis produces four new child cells with two divisions, each of which has half the genetic material of its parent. Mitosis takes place all over the body, while meiosis only takes place in the sex organs and produces sex cells.

A car is traveling with an initial velocity of 15 m/s when the driver decides to go faster by accelerating at 5 m/s2 for 10 seconds. How far did the car travel during this time?
70 m
300 m
175 m
400 m
Answer: Time needed: 2.5 s
Distance covered: 31.3 m
Explanation:
I'll start with the distance covered while decelerating. Since you know that the initial speed of the car is 15.0 m/s, and that its final speed must by 10.0 m/s, you can use the known acceleration to determine the distance covered by
on one side of the equation and solve by plugging your values
To get the time needed to reach this speed, i.e. 10.0 m/s, you can use the following equation

Answer:
Volume of HBr = V₂ = 7.5 mL
Explanation:
Given data:
Volume of NaOH =V₁= 25.0 mL
Molarity of NaOH =M₁= 0.150 M
Molarity of HBr =M₂= 0.5 M
Volume of HBr =V₂= ?
Solution:
M₁V₁ = M₂V₂
0.150 M ×25.0 mL = 0.5 M×V₂
V₂ = 0.150 M ×25.0 mL / 0.5 M
V₂ = 3.75 M.mL /0.5 M
V₂ = 7.5 mL

How could energy have played a role in the different rock types forming?
Answer:
Energy from different sources leads to different types of rocks.
Explanation: Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into different types of rock.
Rocks are formed in earth by the deposition of minerals and decomposition of massive tectonic plates by the hot magma which is melted by the heat energy radiated from sun.
What are different types of rocks?There are broadly three different types of rocks, namely sedimentary rocks, igneous rocks and metamorphic rocks . They are classified based on their formation and composition.
The magma that the molten mineral fluid inside the earth crest melts under heat radiated from sun and this hotter fluid flows results in movement of tectonic plates and decomposition at some places.
Therefore, the heat energy and resultant convection current leads the tectonic plate boundaries and formation of different kinds of rocks which are stimulated by the action of air and water.
