What else can I help you with?
When two substances are combined bubbling is usually a sign of a chemical change?
Bubbling can indicate a chemical reaction is occurring because it often involves the release of gas. This gas production can be a sign that new substances are being formed, which is characteristic of a chemical change. The bubbling may be due to the release of a gas as a product of the reaction.
Are two substances that burst into flames on contact an indication of a chemical reaction?
Yes, it is a chemical reaction.
Bubbling present during a chemical reaction is evidence of what?
Bubbling present during a chemical reaction is evidence of a gas being produced. The formation of gas bubbles indicates that a chemical change is taking place, often as a result of a reaction between two or more substances.
Is an indication of chemical change?
Not necessarily. If the color change is in the presence of 1 or all of the following:a precipitate (insoluable substance)a gas being produced (bubbling)energy being released or absorbed by chemicals,then it is indicating a chemical change.
What substances combine without a chemical reaction?
Substances like oil and water can mix without undergoing a chemical reaction, forming a mixture. Similarly, sugar and water can dissolve into each other without a chemical reaction occurring. These are physical changes where the substances retain their original properties.
Are Effervescent tablets bubbling in water physical properties?
Yes, the bubbling of effervescent tablets in water is a physical property. This is due to a physical reaction between the tablets and water that releases gas, typically carbon dioxide, resulting in the formation of bubbles. The effervescence is a visible indication of this physical change.
Earth has nearly 4000 minerals which are made from naturally occurring elements.?
That is correct. Minerals are solid, inorganic substances that are composed of one or more naturally occurring chemical elements. They have a specific chemical composition and atomic structure.
The production of light when two substances are mixed might indicate that?
a chemical reaction is occurring between the two substances. The release of light is often a sign of energy being produced as a result of the reaction.
Are mixtures and solutions a chemical property?
Mixtures and solutions are not considered chemical properties. They refer to the physical combination of substances without a chemical reaction occurring. Chemical properties relate to the behavior of a substance in chemical reactions, such as flammability or reactivity.
How can you determine if a chemical reaction is occurring, and what are two methods to identify this process?
You can determine if a chemical reaction is occurring by observing changes in the physical or chemical properties of the substances involved. Two methods to identify this process are observing the formation of a precipitate or a color change in the reaction mixture.
Is foaming or bubbling a chemical change?
yes
Solid hormongenous inorganic subtances occurring in nature having a denfinte chemecial composition?
Solid homogeneous inorganic substances occurring in nature with a definite chemical composition are known as minerals. These naturally occurring substances are characterized by their specific chemical formulas and crystalline structures. Minerals are essential components of rocks and are classified based on their chemical composition and physical properties. Examples include quartz, feldspar, and calcite, each with unique characteristics and uses.
