Blue vitriol is a very obsolete name for the copper(II)sulphate: CuSO4. Don't use in the future this term. Pentahydratated copper(II) sulphate: CuSO4.5H2O - bright blue color After the dehydratation of the above compound we obtain the anhydrous copper(II) sulphate: CuSO4 - pale green color.

Is it true during a chemical change the form of a substance is altered but not its identity?
Yes, during a chemical change, the chemical composition of the substance is altered, which means new substances are formed with different properties. However, the identity of the original atoms remains the same, as they are rearranged to form new compounds.
What reaction of matter will stay the same during a physical change?
The chemical composition of the matter will stay the same during a physical change. Only the physical properties, such as shape, size, or phase, will be altered without affecting the chemical composition of the substance.
Which property of matter changes during a chemical change but does not changes during a physical change?
The composition of matter changes during a chemical change as new substances are formed with different chemical properties. In contrast, the composition of matter remains the same during a physical change, with only the physical state or appearance of the substance being altered.
During the periods humans altered their habitats?
humans always do
HOW TISSUE EMBOSSING CHANGES THE CHARACTERISTICS OF TISSUE ROLLS?
How tissue embossing Changes the characteristics of tissue rolls For tissue-paper products, in particular paper towels, mechanical strength is one of the most important features. The paper towels’ physical properties depend on the physical characteristics of the material from which they were produced, but during paper processing, these properties are altered, particularly during the embossing stage.😎
How is water cycle altered during drought?
There is no precipitation during droughts. Water becomes scarce.
During what process does the make-up of a rock become altered?
A rock can be altered compositionally by chemical weathering or by metamorphosis through heat and pressure.
A change during which the basic composition of the substance is not altered is?
Physical Change
What is the form or appearance of matter altered during a change?
During a change, the form or appearance of matter can be altered through physical or chemical processes. In physical changes, such as melting or dissolving, the substance retains its chemical identity but changes state or shape. In chemical changes, such as combustion or rusting, the matter transforms into new substances with different properties. These alterations can affect color, texture, state (solid, liquid, gas), and other physical characteristics.
What takes place during a chemical change?
During a chemical change, the identity and composition of a substance are altered as new chemical bonds are formed or broken. This change is usually irreversible and produces a new substance with different chemical properties compared to the original materials. Examples include combustion, oxidation, and digestion.
In a physical changethe makeup matter is changed true or false?
False. In a physical change, the makeup of matter remains the same, only the physical properties like shape, size, or state are altered. No new substances are formed during a physical change.
Who recently altered the periodic table?
SOME American during the world war
