In a voltaic cell, electrons flow from the anode to the cathode. Anode is negative while cathode is positive.
In an electrolytic cell, electron flows from the cathode to the anode. Anode is positive and cathode is negative.
For both, Oxidation occurs at the anode and Reduction occurs at the cathode.
Answer:
Option c.
Explanation:
Convection - transfer of heat mode is that technique of transfer of heat in which heat and thermal energy can be transferred from one point to another point in the system by the random movement of the molecules of the fluid. This method of transfer of heat or the mechanism of transfer of heat by convection is the most dominant form of transfer of heat in gases and liquids.
Therefore, we can say that convection involves the transfer of heat as a result of the macroscopic and some random movement of the fluid molecules.
Answer:
0.333 mol NH₃
Explanation:
N₂ + 3 H₂ ⇆ 2 NH₃
This is the reaction that produces NH₃. Use the mole ratios to solve. For every 3 moles of H₂ that are consumed, 2 moles of NH₃ are produced.
(0.500 mol H₂) × (2 mol NH₃/3 mol H₂) = 0.333 mol NH₃
You will produce 0.333 moles of NH₃.
Answer:
Carbonated water is a mixture,
Explanation:
which means it contains two or more different chemicals.
Is Sodium Hydroxide an element, mixture, or compound?
An example would be placing sodium (Na) in water (H2O). Sodium creates a new chemical bond producing a new substance with new physical and chemical properties known as sodium hydroxide (NaOH). So, if a new chemical formula must be written after two or more substances combine it is not a mixture.
Answer:
259.08
Explanation:
if you see 102 times 2.54 = that number is right answer
