No, the difference between a pure substance and a mixture is not always easy to observe. While pure substances have definite chemical compositions and properties, mixtures consist of two or more substances physically combined. Some mixtures can be challenging to distinguish from pure substances based on visual observations alone.
Chemical changes are considered unseen because they occur at the atomic level, changing the actual structure of the thing. This is in comparison to a physical change, which is visible.
Metals have certain features which make them easy to recognize. They have a metallic luster, and they are very good conductors of electricity. They undergo chemical reactions in which they lose electrons. Non metals characteristically do not have a metallic luster, do not conduct electricity very well, and they undergo chemical reactions in which they gain electrons (or in the case of inert gases, they don't undergo any chemical reactions).
Bubble formation is a sign of gas being produced in a reaction, bangs can be caused by a rapid release of energy in an exothermic reaction, and burning typically indicates a combustion reaction where a substance reacts with oxygen to produce heat and light. Each of these phenomena provides valuable information about the nature of the chemical reaction taking place.
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.
Yes, age will affect human reactions. As you get older, your reaction time is slower and it can often not always be easy to make the best decisions.
No, vibrational motion is often difficult to observe with the naked eye because it occurs at a very fast rate and with a small amplitude. Special equipment such as high-speed cameras or scientific instruments like spectrometers are typically needed to study vibrational motion closely.
No.
It is not easy to revert a compound back into its original elements because chemical reactions that form compounds are often irreversible. Breaking apart a compound into its constituent elements typically requires a complex and energy-intensive process, such as electrolysis or high-temperature reactions.
This type of reaction is likely a reversible reaction, where the products can easily be converted back into the reactants. Reversible reactions often reach an equilibrium state where the forward and reverse reactions occur at equal rates.
Look at it, it is visible with the naked eye. you can also use a telescope and i don't think it is very easy to see it at some points.
The reason it's often easy to miss an action-reaction pair is because of the unequal mass or magnitude of one of the objects involved. This can lead to one of the reactions being more noticeable than the other, causing the pair to appear unbalanced or incomplete.
