Find the molar mass of fe2o3. Then multiply 4.3 x molar mass of fe2o3/1 moles
True, because a liquid can be taken and added, but a solid stay the same never losses and never gains
Pick C Because it's
Explanation:
a chemical reaction in which one element replaces another in a compound. F₂ + 2NaCl → 2NaF + Cl₂, where F replaces Cl in NaCl. A double-replacement reaction is a reaction in which the metals in two ionic compounds exchange partners.
Neither N₂ or O₂ are greenhouses gases because they do not cause the greenhouse effect.
<h3>What are greenhouses gases?</h3>
Greenhouse gases trap heat in the atmosphere causing the temperature of the planet to rise.
Greenhouse gases cause the greenhouse effect.
<h3>What is the greenhouse effect?</h3>
The greenhouse effect is the warming up of the planet due to greenhouse gases.
Greenhouse gases include
- carbondioxide
- methane
- nitrous oxide and
- water vapour
So, neither N₂ or O₂ are greenhouses gases because they do not cause the greenhouse effect.

Answer:
The answer is D. The concentrations are different and the reactions are different, so the cell potential is 0.00 volts.
Explanation:
A concentration cell is an electrolytic cell that is comprised of two half-cells with the same electrodes, but differing in concentrations. A concentration cell acts to dilute the more concentrated solution and concentrate the more dilute solution, creating a voltage as the cell reaches an equilibrium.
