Answer:
28 grams
Explanation:
The equation for the reaction is
3H(2) + N(2) -> 2NH(3)
Then we have.
The molar mass, M of ammonia is 17 g/mol.
34 grams of ammonia, NH3 then would be
34 g / 17 g/mol
= 2 moles
2 moles of ammonia will be obtained from
(2 * 1) / 2
= 1 mole of nitrogen
The molar masses of nitrogen is 28 g/mol
2 moles of nitrogen corresponds to 1 * 28 = 28 grams.
Answer:
This reason is that Japan is located along the Pacific 'ring of fire' which is an area along the Pacific plate boundaries where there is a lot of volcanic activity
Explanation:
Japan also lies on the edges of several continental and oceanic plates so this is why Japan experiences a lot of earthquakes.
Answer: D.ultraviolet rays, visible light, infrared radiation, microwaves.
Explanation:
Shorter wavelength means higher frequency and higher energy.
Thus, the correct sequence of electromagnetic waves from shorter wavelength to longer wavelength is:
D.ultraviolet rays, visible light, infrared radiation, microwaves.
<u>Ultraviolet rays have shorter wavelength (about 380 nm) and high energy. </u>
<u>Visible light has wavelength: 380 nm to 700 nm</u>
<u>Infrared wavelength: 700 nm to 1 mm</u>
<u>Microwave wavelength: 1 mm to 1 m</u>
Explanation:
Please attach the figure next to your question in order to help you.. Wish u the best and Have a great Day. Good Luck!
<span>The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come.</span>
