Electrolysis of water involves the decomposition of water into oxygen and hydrogen gas by passing an electric current through water. The positively charged ion (hydrogen ion) moves to the negative electrode (cathode) during electrolysis, while the negatively charged ion (OH-) moves to the positive electrode (anode). Therefore, the half equation that occurs at the cathode during the electrolysis of water will be;
4H+(aq) + 4e- = 2H2 (g)
<u>Answer:</u> Moles of iron for the given amount is 17.90 moles.
<u>Explanation:</u>
We are given 1 kg of iron and we need to find the moles of it. To calculate the moles, we use the following equation:
Mass of iron given = 1kg = 1000 grams (Conversion Factor: 1 kg = 1000g)
Molar mass of iron = 55.85g/mol
Putting values in above equation, we get:
Hence, moles of iron for the given amount is 17.90 moles.
The latter contains hydroxyl ions when dissolved in water making it basic.
Answer:
Explanation:
Reducing agent
Reducing agent is an element or compound that loses or donates an electron to another chemical species in a redox chemical reaction. Since the reducing agent is losing electrons,it is said to have been oxidized.
Answer:
DNA sequence
Explanation:
When we say our DNA is different , we mean the sequence, or coding, of DNA is different
