Answer: The chemical formula of a zeolite is Na2. Al2O3. nSiO2 Permutite is an artifical zeolite used for softening of water. Through ion-exchange process, here cation-anion exchange chamber is used to obtain pure water. In calgon's process sodium hexa meta phosphate is used to soften the water.
Explanation:
Answer: Chemical equation
Explanation: In writing a chemical equation, the correct formula and symbols of the reactants are written on the left hand side of the equation while those of the products are written on the right hand side. A horizontal arrow is drawn between the two sides to indicate the direction of the reaction.
Example: Na + Cl -> NaCl
The balanced equation is:
2NaCl + 2 H2o → 2 NaOH + Cl2 + H2
1- we put 2 NaCl to balance Cl2 on the other side.
2- we put 2 NaOH to balance Na
3- We put 2 H2O to balance H & O on the to sides
Answer:
Both answer choice 2 and answer choice 3 are correct choices.
Explanation:
Biotic factors are living components in an ecosystem. They are living organisms which affect another living component in an ecosystem.
Antibiotic factors are non living components of an ecosystem. They are chemicals which affect living organisms.
The choice 2 is correct. The seeds spread out by mice is a biotic factor interacting with an antibiotic factor
Choice 3 is correct. The seeds in the soil grow into new trees are biotic factors interacting with an antibiotic factor
