Idk.... my grade in the school C (about chemistry)
Answer:
A = 0.023 m
Explanation:
The relation between the frequency of a radiation and its wavelength is given by the following expression.
where,
c is the speed of light (it has a constant value of 3.00 x 108 m/s)
A is the wavelength of the radiation v is the frequency of the radiation
In this case, the frequency is 13 GHz = 13 x
10° Hz = 13 x 1o° s-
The wavelength associated with this frequency is:
A = c/v = (3.00 x 10° m/s)/(13 x 10° s-") = 0.023
x + y = 100
0.10x + 0.45 y =25
eliminate
x + y = 100
x + 4.5 y = 250
-3.5 y = -150
y = 42.85
x = 57.15
hope this helps
Not all matter in the reactant goes to the product. Some matter is byproducts.
Answer : Option D) Distilled Water.
Explanation : As the definition of the compound says,it is made up of two or more different elements in combination which is not easily seperable.
The only answer that was relevant to this definition is distilled water as it is made up of combination of hydrogen and oxygen atoms.
