Answer:
1. How many electrons does hydrogen need in order to have a full shell of valence electrons?...two
2. How do valence electrons impact the type of bonds an atom makes?...An atom wants a full outer shell of valence electrons, so it will either transfer or share electrons depending on what the other atom needs.
3.Use your knowledge of valence electrons and how they affect bonds to figure out how carbon (Group 14) and oxygen (Group 16) would be attached to one another. In carbon dioxide (CO2), how is the compound structured? (Use “–” to represent a single bond and “=” to represent a double bond.)...O=C=O
4. Methane’s chemical formula is CH4. Is there a bond between any of the hydrogen atoms? Why or why not?...No, there is not because carbon needs four bonds, so it bonds with each hydrogen atom; hydrogen only forms one bond.
5. In hydrogen peroxide (H2O2), which option best shows how the atoms are ordered?...H-O-O-H

Answer:
absorbed
Explanation:
because black absorbs the light around it
First you have to find the number of moles , then you have to apply stoichometry to find the number of moles of H2 gas , after that you can determine its mass.
