Answer: So if you had 570 cm of ribbon, then 570%2F8.5=67.05 which means that about 67 students can do the experiment (round down to the nearest whole number).
Explanation: If you had 8.5 cm of ribbon, then only 8.5%2F8.5=1 student can do the experiment. If you had 17 cm of ribbon, then 17%2F8.5=2 students can do the experiment.
C) elements from the top left and the top right of the periodic table
Answer:
Explanation:
The answer is that "elements are a single atom and compounds are a mixture of two elements or more." Elements are atoms that have protons, neutrons, and electrons. Compounds are mixtures with two or more elements.
Hope this helps.
After the dillution of the solution, the wavelength of maximum absorption is decreased.
<h3>What is the wavelength of maximum absorption?</h3>
The wavelength of maximum absorption is the wavelength at which the solution absorbs the maximum amount of light. It is usually shown as a hump in the spectrum.
When the starting concentration of the K2Cr2O7 is diluted, the wavelength of maxium absorption decreases.

As Bond energy is between carbon and oxygen the is 358 for a single bond of C-0 and 745 for a double bond is the c=0.
- In the first step the one atom pulls the electron from another atom
. In the second step that is forming bonds releases energy and is the exothermic
. In the third step they pull electrons away from other elements
.
- In the last step the additional bonds is needed more energy to make or break, so the bond energy is very higher Hence the -153.
Learn more about the energy between carbon and oxygen is 358.
