D.) "Vaporization" <span>is not a form of heat transfer.
It is just conversion of the state of matter from Liquid to Vapor
Hope this helps!</span>
Hello!! Your answer would be 3.33x10^-10. Since you are trying to find one place holder for the notation, you will move your decimal 10 times to the right for it to be in scientific notation. Always remember that for scientific notation, you must have one whole number in front of a decimal at all times. After you put the decimal after the first whole number, count how many times you have moved your decimal. If you have a lot of zeros in front of your numbers, you will always have a negative exponent, and if you have a negative exponent, then you will have a lot of zeros. If you have a whole number exponent, it will be up in the 100s, 1000s, or 10000s, something like that. It will have a high value with a higher exponent. I hope I helped!! If you have any more questions then do not hesitate to message me and let me know. Have a great day!! :)
The answer is a I’m pretty sure
Answer: Option (c) is the correct answer.
Explanation:
When current passes through a wire then a magnetic field is formed. Therefore, when two wires carry current in the same direction then both the wires with have respective magnetic fields in the same direction and their total magnetic field will be large.
But when current between two wires flow in opposite direction then the magnetic field produced will also be in opposite direction. Therefore, both the magnetic fields cancel each other out. Thus, total magnetic field will be small.
As a result, wires which carry current in the opposite direction repel each other.
Answer:
The mass of PCl₃ is 332.3 g.
The molecules of PCl₃ is
Explanation:
Given that,
Mass of P₄ = 75.0 g
Mass of Cl₂ = 275 g
We know that,
The reaction is
We need to calculate the moles of P₄
Using formula of moles
Put the value into the formula
We need to calculate the moles of Cl₂
Using formula of moles
Put the value into the formula
We need to calculate the number of moles of
Moles in 1 P₄ = 0.61
So,
We need to calculate the mass of
Using formula of mass
Put the value into the formula
We need to calculate the molecules of
Using formula of molecules
Where, n = number of moles
N = avagadro number
Put the value into the formula
Hence, The mass of PCl₃ is 332.3 g.
The molecules of PCl₃ is
