Substance produced by a chemical reaction?
A product is a substance formed during a chemical reaction. It is the result of the reaction's course and might have different physical or chemical properties than the reactants.
How might a thermometer help you decide if there was any chemical change on mixing iron and charcoal?
For a chemical change to occur, there must be a chemical reaction. A chemical reaction would be either endothermic (uses energy, mostly heat), or exothermic (produces energy, again mostly heat). Any change in temperature of the reactants, as measured by a thermometer, will tell you not only ifa chemical reaction occurred, but also which kind of chemical reaction. No temperature change usually indicates that no reaction has occurred, a decrease in temperature would indicate an endothermic reaction, while an increase in temperature would indicate an exothermic reaction.
What evidence of a chemical reaction might you see dropping an alka-seltzer tablet into a glass of water?
You might observe fizzing or bubbling as the tablet dissolves in the water due to the release of carbon dioxide gas. This effervescent reaction is evidence of a chemical reaction occurring between the ingredients in the tablet and water.
When you burn magnesium in air what might show you a chemical reaction has taken place?
A chemical reaction taking place when burning magnesium in air can be indicated by the bright white flame and the formation of magnesium oxide, a white powder that forms on the surface of the magnesium. Heat is also released during this exothermic reaction.
What is called chemical reaction rate?
The speed of the reaction
What might be formed in the chemical reaction H202?
H2O2 is not a chemical reaction, it is Hydrogen Peroxide.
Substance produced by a chemical reaction?
A product is a substance formed during a chemical reaction. It is the result of the reaction's course and might have different physical or chemical properties than the reactants.
Could you tell me about a silver dollar that turned blue can you tell me anything about that?
It might be a chemical reaction from water if the metal itself is blue. Otherwise, it might be stained from food or paint.
What simple test might be undertaken to check if a chemical reaction produces oxygen?
glowing splint ... if it relights then the chemical reaction produces oxygen.
What Three Things can happen when a Chemical Reaction occur?
A chemical reaction can change a substance into a solid, liquid, or gas. It may cause a substance to explode or could cause no change at all.
What evidence of a chemical reaction might you see by rusting of an iron nail?
oxidation
What might release energy during a chemical reaction?
a cake anything cooked
Do catalyst produce chemical reactions?
yes chemical reactions in order to induce a chemical reaction that might normally take a long time
Give three things you might see if a chemical reaction takes place?
There are many observations that may occur when a chemical reaction takes place. Some of the things are:- Change of colour, change of temperature change of state. These can be observed by the features below There might be a change in colour when mixing the reactants; the vessel in which the reaction is taking place might get warm on the outside or cold depending on the type of reaction. There may be effervescence or fizzing with gas production; a precipitate may form.
What type of chemical reaction is this caCO3 CaO CO2?
Decomposition Reaction
What evidence of a chemical reaction might you see when burning a match?
Volatile compounds in the wood undergo combustion, or reaction with oxygen, forming H20 and CO2 gases. Because of the makeup of wood being mostly carbon-based compounds, this reaction leaves behind soot and charcoal.
What from of energy might be needed for a chemical reaction to take place?
heat & electric energy !
