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)
Answer:
true
boiling is a bulk phenomena
<span>Chromium(II) sulfate
this is an ionic compound of a metal and a polyatomic ion.
chromium is a metal that can form more than one type of cation. In this case, the polyatomic ion name is sulfate and it has 2 negative charges. Then Cr has to have 2 positive charges.
then write the name of the metal followed by the charge of the ion between parenthesis and in roman numbers followed by the name of the polyatomic ion.</span>
Answer:
Biotic and abiotic are the two essential factors responsible for shaping the ecosystem. The biotic factors refer to all the living beings present in an ecosystem, and the abiotic factors refer to all the non-living components like physical conditions (temperature, pH, humidity, salinity, sunlight, etc.) and chemical agents (different gases and mineral nutrients present in the air, water, soil, etc.) in an ecosystem. Therefore, both the abiotic and biotic resources affect survival and reproduction process.
Furthermore, both these components are reliant on each other. Suppose if one of the factors is removed or altered, its repercussions will be faced by the entire ecosystem. Without a doubt, abiotic factors directly affect the survival of organisms. Read on to explore what role do abiotic and biotic resources play in the ecosystem.
