second compound
Let molar mass of x is = X
Let molar mass of y is = Y
Moles of x in second compound = Mass / molar mass = 7 / X
Moles of y in second compound = Mass / molar mass = 4.5 / Y
For second compound
7 / X : 4.5/ Y = 1:1
Therefore
X / Y = 7/4.5
Y / X = 4.5/ 7
The mass of x in first compound = 14g
moles of x in first compound = 14/X
Mass of y in first compound = 3
moles of y in first compound = 3 / Y
14 / X : 3/ Y = 14Y / 3X = 14 X 4.5 / 3 X 7 = 3 :1
Thus molar ratio in first compound = moles of x / Moles of y = 3:2
Formula = x3y
Answer:
The correct answer is - Orange light reflected from the t-shirt enters human eyes.
Explanation:
Human eyes and brain are altogether able to detect the color of the object by translating the light which is reflected by the object and transmitted by the light receptors in the eyes ad brain translate light to color.
The objects are able to absorb some colors and reflect others on the basis of their wavelength, The reflected colors are detected by our eyes and brain and objects appear to be a particular color. like here, the orange color is reflected by the t-shirt and enters in human eyes.
The electrons and the nuclei will settle into positions that minimize repulsion and maximize attraction.
The correct option is A,
Isotopes are atoms of an element, which have the same number of protons but different number of neutrons in the nucleus of the atom. Thus, isotopes have the same atomic number but different mass number.
Looking at the options given above, you will discover that Chlorine which is given in option A is correct. Both type of chlorine has the same atomic number, which is 17, but they have different atomic masses, the atomic mass of the first one is 35 while that of the second one is 37.<span />
