Answer:
The answer is below
Explanation:
They are isotopes. Isotopes are molecules that have the same atomic number but have different atomic mass because the number of neutrons is different.
Iodine has an atomic mass of 126 g and its atomic number is 53.
# of neutrons = 126 - 53 = 73
Its isotope has an atomic mass of 128 g its atomic number is also 53, but the number of neutrons is different.
# neutrons = 128 -53 = 75
We have this function for kinetic energy :
We find this from the above function :
Due to this equation, the mass of an object and its velocity are inversely proportional to each other.
Therefore, as the mass increases, the speed decreases and the thrown object travels a shorter distance.
And we're done...
Thanks for watching good luck ♥️♥️♥️♥️♥️.
Answer:
I think that 142.5 is the answer.
<span>oxidizing agent removes an electron from other specie
the oxidizing agents are reduced due to loss of electrons
</span><span> F2 is reduced from neutral state to 1- so it act as an oxidizing agent
</span>so correct option is A
hope it helps
Answer:
C₂H₄O
Explanation:
Empirical formulas show the simplest ratio of atoms in a compound in whole numbers.
We can think that all the atoms are divisible by 4.
As we need the lowest number for each subscript, empirical formula is:
C₂H₄O
We have divided, 8/4 for carbon, 16/4 for H and 4/4 for O.
The empirical formula is also known as the simplest expression to represent a chemical
