Answer:
A) Nonmetal carbon shares valence electrons with each nonmetal hydrogen forming four covalent bonds.
Explanation:
Methane is formed when nonmetal carbon shares valence electrons with each nonmetal hydrogen forming four covalent bonds. Nonmetals share electrons to form covalent bonds.
Good luck! :)
Answer:
e) The activation energy of the reverse reaction is greater than that of the forward reaction.
Explanation:
- Activation energy is the minimum amount of energy that is required by the reactants to start a reaction.
- An exothermic reaction is a reaction that releases heat energy to the surrounding while an endothermic reactions is a reaction that absorbs heat from the surrounding.
- <em><u>In reversible reactions, when the forward reaction is exothermic it means the reverse reaction will be endothermic, therefore the reverse reaction will have a higher activation energy than the forward reaction.</u></em> The activation energy of the reverse reaction will be the sum of the enthalpy and the activation energy of the forward reaction.
1identify the #
2place a decimal in a location which would make a #between 1and9
3 count the # of space values that the decimal moved
4 plug the numbers into this formula number from step 2×10 place value
example:
1) 330,000
2) 3.3 0000
3) count the places moved 5
4)plug the # in 3.30×10 to the 5th power.
Your answer would be shorter wavelength and equal speed !
