Answer:
The frequency of light ranges from 430 trillion hertz to 750 trillion hertz
Explanation:
It is usually measured on the Pauling scale, on which the most electronegative element (fluorine) is assigned an electronegativity of 4.0. Each of these elements has a low electronegativity on the Pauling scale, and the electronegativities clearly decrease down the group.
Answer:
3 HNO₃ + Fe(OH)₃ → H₂O + Fe(NO₃)₃
Explanation:
An acid reacts with a base producing water and a salt. Having this in mind the reaction of nitric acid (HNO₃) and Iron (III) hydroxide (Fe(OH)₃) is:
HNO₃ + Fe(OH)₃ → H₂O + Fe(NO₃)₃
<em>The H⁺ of the acid reacts with the OH⁻ to produce H₂O. The other ions (Fe³⁺ and NO₃⁻) produce the salt</em>

There are 3 nitrates in products. To balance the nitrates:
<h3>3 HNO₃ + Fe(OH)₃ → H₂O + Fe(NO₃)₃</h3>
<em>And this is the balanced reaction</em>

You have to use density=mass/volume formula:
Solve for x and you get
2282.75 grams
Answer:
infrared waves are longer than gamma rays
Explanation:
according to the order :
radio, microwaves, infrared, light, ultraviolet, X-ray, gamma rays
radio waves have the highest wavelenght and lowest frequency, gamma rays have the highest frequency and lowest wavelength.
