Hi!
Fuel-cell cars only release water and heat in the atmosphere.
Since they are only run by oxygen and hydrogen to produce electricity in the motor, they don't emit carbon dioxide or greenhouse gas as what other people think.
Basically, automotive engineers and scientist classified them as zero-emission.
Answer:
<em>C. It increases as you move left to right within a period and up a group on the periodic table.</em>
Non-renewable energy takes a huge amount of time to be naturally created and replenished. Many hundreds of lifetimes, in fact. On the other hand, renewable energy sources are replenished pretty quickly. Biomass is a renewable energy from plants and animals. Biomass is renewable organic material that comes from plants and animals. Biomass was the largest source of total annual U.S. energy consumption until the mid-1800s.
At the anode, half-cell oxidation occurs in a voltaic cell.
<h3>Voltaic Cell Principle</h3>
A voltaic cell generates electricity due to the Gibbs free energy of spontaneous redox processes occurring inside the cell, which is the basis for the voltaic cell's operating principle.
Two half-cells plus a salt bridge make up the voltaic cell. An electrolyte-immersed metallic electrode is present on each side of the cell. These two half-cells are wired together to form a connection to a voltmeter.
<h3>Voltaic Cell Parts</h3>
- Copper makes comprises the cathode of a photovoltaic cell. This electrode serves as the cell's positive terminal, where reduction takes place.
- Anode: Zink metal makes up this electrode. It creates the cell's negative electrode, where oxidation takes place.
- Oxidation and reduction are divided into two discrete parts in two half-cells.
- Salt Bridge: It contains the electrolytes needed to finish the circuit in the voltaic cell.
- The flow of electrons between the electrodes occurs via the external circuit.

Explanation:
1L=1000mL
1dm³=1L
1dm³=1000cm³
29.84ml-29.00ml=0.84ml
Density=mass(g)/volume(cm³)
=6.6g/(0.84cm³)
=?
