In 1kg mixture of sand and iron. 2000 is iron. How much ...Description for Correct answer: Amount of iron in 1 kg mixture = 20% of 1000 gms = ( Large frac{20 times 1000}{100} ) = 200 gms Therefore, Amount of sand in mixture = (1000 200) gms = 800 gms Now, let the total mixture is x kg in which iron is 20% Therefore, According to question, 50% of x = 200 gm ( Large frac{5 times x}{100} = 200 gm ) ( Large x = frac{200 times 100}{5 ...
Easy Heterogeneous Mixture ExperimentSand is an example of a heterogeneous mixture. Look closely at a handful of sand and you will see all the different colors and shapes of the substances that make up sand. You might need a hand lens (magnifying glass) to really see, but the variations are there. (For an even more fascinating view of sand, check it out under a microscope!)

Answer: If the chemical composition is changing, then it is a chemical change, and if the chemical composition is remaining the same, then it is a physical change.
Chemical Engineering Journal" Mixing iron metal (Fe0) and sand is a conventional approach in designing Fe0 filtration systems. " Reliable concepts to optimize Fe0/sand systems are still lacking. " Methylene blue () discoloration is used to characterize the efficiency of Fe0/sand systems. " Results demonstrate that sand impairs discoloration by Fe0 as a rule.

Background information Year 7, unit 1: Mixing and separatingThe term 'filtering' is generally used when the mixture contains a solid and a liquid, for example sand and water. When a sieve is used, the process is usually referred to as sieving. For example, a mixture of sand and gravel is separated using a sieve and works because the gravel particles are much larger than the sand particles. When a
