Answer;
D.
infrared, visible, ultraviolet
Explanation;
Electromagnetic waves are types of waves that do not require a material medium for transmission. An electromagnetic spectrum arranges these electromagnetic waves in the order of increasing frequency and decreasing wavelength.
The spectrum consists of , Radio waves, microwaves, infrared, visible light, UV light, X-rays and Gamma rays; arranged in order of decreasing wavelength and increasing frequency.
Radio waves have the longest wavelength but the lowest frequency, while gamma rays have the lowest wavelength but the largest frequency.
Answer:
Boiling water breaks intermolecular attractions and electrolysis breaks covalent bonds.
Explanation:
When water boils, hydrogen bonds are broken between adjacent water molecules. The hydrogen bond is an intermolecular bond between adjacent oxygen and hydrogen atoms of water molecules.
During electrolysis, water dissociates in the presence of electric current. Here, ions are formed in the process. Therefore, covalent bonds are broken here.
The time taken to the nearest tenth of a minute, would it take the element to decay to 98 grams is 9.897.
<h3>What is half-life?</h3>
Half-life is the time half-time of the total decay of any element.
Given that, Initial amount = 970 grams
Final amount = 98 grams
Half life = 13 minutes
To find the half life
Thus, the time taken to the nearest tenth of a minute, would it take the element to decay to 98 grams is 9.897.

Hello!
From tables, we know that the
pKa for Methylamine CH₃NH₂ is 10,61. Now, we can apply the
Henderson-Hasselbach's equation and clear for the ratio of CH₃NH₂ to CH₃NH₃Cl
So, the ratio of CH₃NH₂ to CH₃NH₃Cl should be
0,32Have a nice day!
