Answer:
Empirical formula is NH₃
Explanation:
Given data:
Percentage of hydrogen = 82%
Percentage of nitrogen = 18%
Empirical formula = ?
Solution:
Number of gram atoms of H = 18 / 1.01 = 17.8
Number of gram atoms of N = 82 / 14 = 5
.9
Atomic ratio:
H : N
17.8/5.9 : 5.9/5.9
3 : 1
H : N = 3:1
Empirical formula is NH₃
Answer:
The wavelength of this light is 780.4 nm.
Explanation:
Given that,
The frequency of laser light,
We need to find the wavelength of this light.
We know that,
Where
is the wavelength of light
So,
So, the wavelength of this light is 780.4 nm.
Answer:
H3PO4
Explanation:
The H3PO4 is an acid as it release H+ ion when dissolved in a solution and H3PO4 is known as phosphoric acid
Higher. Because this type of heat transfer is conduction, meaning that heat always transfers to cooler objects.
