How do you describe the process of cellular respiration?
Cellular respiration is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen.cellular respiration- process that release energy by breaking down glucose and food molecule in the presence of oxygen.
What are polydactyly and syndactyly?
Polydactyly is the term for the presence of extra fingers. Syndactyly is the term for fused fingers.
Suppose the original sample is unknowingly contaminated with a second anhydrous salt will the reported percent water in the hydrated salt be too high too low or unaffected by its presence?
If the original sample is unknowingly contaminated with a second anhydrous salt, the reported percent water in the hydrated salt will be too low. This is because the presence of the anhydrous salt will increase the overall weight of the sample without contributing to the water content calculation, leading to a lower reported percentage of water in the hydrated salt.
What is meant by anhydrous AlCl3?
Anhydrous AlCl3 refers to aluminum chloride that is free from water molecules. It is a dry, solid compound that is commonly used as a catalyst in chemical reactions. Its anhydrous form is important in certain reactions where the presence of water can interfere with the desired outcome.
Test for presence of water in anhydrous copper sulphate?
To test for the presence of water in anhydrous copper sulfate, heat a small sample of the compound in a test tube. If the compound changes color from white to blue, it indicates that water is present in the compound. This color change happens as the anhydrous copper sulfate absorbs water vapor from the air, converting back into hydrated copper sulfate.
How are hydrated salts different from anhydrous salts?
A hydrated salt has a number of waters of hydration combined to each molecule of salt whereas an anhydrous salt is one that has had its waters of hydration removed. An example of a hydrated salt is nickel sulfate hexahydrate, NiSO4·6H2O. The waters of hydration can be removed by a simple heating, resulting in NiSO4(s) + 6H2O(g).
Why anhydrous copper II chloride is used to test for the presence of water?
Anhydrous copper II chloride is used to test for the presence of water because it readily absorbs moisture. When anhydrous copper II chloride reacts with water, it forms a blue-green hydrated copper II chloride compound, helping to detect the presence of water by a visible color change.
When added to copper sulphate what colour is anhydrous copper sulphate?
anhydrous copper sulphate is white. when water is added it turns blue, in essence it can be used to detect the presence of water. hope this helps!!!!!!!!!!!
What is meant by the word anhydrous when applied to a chemical?
Anhydrous simply means 'without water'. The opposite is a hydrated substance, in which salt crystals contain water as an integral part of the crystal. For example, anhydrous cobalt(II) chloride, CoCl2, is a blue powder. Add water and you form cobalt(II) chloride hexahydrate, CoCl2.6H2O, which is a pink colour. Anhydrous cobalt chloride can be used to test for the presence of water because of this dramatic colour change. In addition, hydrated copper(II) sulfate, CuSO4.5H2O, forms bright blue crystals. Heating them drives off the water of crystallisation and anhydrous CuSO4, a grey/white powder, is formed. Adding water will reform a blue solution of the hydrated salt.
In the presence of water what happens to anhydrous cobalt chloride?
Anhydrous cobalt chloride will absorb water and form hydrated cobalt chloride. This process is reversible, with the hydrated cobalt chloride releasing water vapor to revert back to anhydrous cobalt chloride when heated.
What is the color of copper sulphate?
Copper sulfate itself is white/colorless when anhydrous. However, it's hygroscopic and the pentahydrate (the usual form) is blue... in fact, it's just about the same color as the sidebar over to the left there.
What is anhydrous?
A hydrated crystal in one that has water molecules trapped inside the crystal structure of some other compound, typically an ionic compound. The water is chemically combined with a substance in such a way that it can be removed, as by heating, without substantially changing the chemical composition of the substance. As a good example, copper sulfate is a commonly hydrated crystal. To show that it is hydrated, you would write CuSO4 . 5H2O. By putting a dot in between the two, it indicates that they are waters of hydration, not really part of the compound (you can remove them by heating the crystals). You can see in this case, there are 5 water molecules for each CuSO4.
Solids tends to be hydrated in the presence of water?
ionic!!!
What is the different between a hydrated salt and anhydrous salt?
Hydrated salt-Salt with water of crystallization are called hydrated salt. Those water are bonded with dative bonds though.Anhydrous salt-Salt which have lost their water of crystallization are called anhydrous salt.
