Hydrogen fuel cells that operate at lower temperatures use more expensive platinum electrode catalysts. what to make up for the higher-cost electrodes? a) they use a cheaper fuel. b) they operate at a higher efficiency. c) they use a reaction that is not redox. d) they produce fewer emissions.

They operate at a higher efficiency.

Explanation:

The expensive electrode catalysts like platinum are more efficient and are inert in nature. They can be used again and again and provides better surface for any reaction.

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
