Answer:
• Hydrogen and oxygen atoms
Explanation:
Hydrogen and oxygen are nonmetals. They are most likely to share electrons and form a covalent bond.
A is wrong. Gold is a metal, so it will form metallic bonds.
O is wrong. Neon is a noble gas. It has a complete octet, so it is unlikely to form covalent bonds.
D is wrong. Mg is a metal, and Br is a nonmetal. They are more likely to form ionic bonds.
Different elements emit different spectra when their electrons get excited because each element has a different arrangement of electrons surrounding the nucleus. The energy levels in which the electrons can occupy are unique to a specific element. When an electron gets excited into a higher energy level, it will eventually relax back into its original state and emit light corresponding to that energy.
Answer:
C 30 degrees after 25 minutes
Explanation:
A reaction is exothermic if heat is evolved as the reaction proceeds. How do we know if heat was given out in the course of the reaction? We have to measure the temperature of the system using a thermometer as the reaction progresses.
If the temperature becomes higher than room temperature (25 degrees), we can now conclude that the reaction is exothermic and heat was indeed given out during the course of the reaction.
I think it say go rggdggy and do something with one of those other things and get a work order and get the t off and u I know I have
