Answer:
20%
Explanation:
mass by mass percentage of a solution =(mass of solute)/(mass of solution)
mass of solute=550g
therefore 110×100/550=20%

X-rays have much shorter wavelengths and higher frequencies. Likewise, red light has a longer wavelength than blue light.
If I heat a reaction then the rate will increase because the higher the temperature the faster the reaction.
Please vote my answer brainliest. thanks!
Answer:
Alkanes contain only carbon-carbon and carbon-hydrogen bonds. Because carbon and hydrogen have similar electronegativity values, the C—H bonds are essentially nonpolar. Thus, alkanes are nonpolar, and they interact only by weak London forces.
