What should not be used to indicate a chemical reaction?
Change of shape can not be used to indicate a chemical reaction has happened. Examples of evidence of a chemical reaction are changes in odor or color.
Can the development of a solid can indicate the occurrence of a chemical change?
Yes
What is the chemical structure of solid?
The chemical formula for solids is like the regular chemical formula of an element or compound. The only difference is that an "(s)" is added next to the right end of the formula to indicate the phase. Example: What is the chemical formula of solid sodium chloride (NaCl) ? Chemical formula: NaCl Chemical formula to indicate that it is a solid: NaCl (s) Additional information: The "(s)" abbreviation is used to indicate that the compound is a solid. A "(g)" abbreviation is used to indicate that the compound is a gas. A "(l)" abbreviation is used to indicate that the compound is a liquid. An "(aq)" abbreviation is used to indicate that the compound is dissolved, and therefore soluble, in water.
How do chemist indicate a reversible reaction when writing a chemical equation?
With this symbol:
What are the uses of chemical formulas?
The uses of chemical formulas are mainly to show how the various elements are in any compound. This will indicate how a particular chemical reaction takes place.
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 does the hot tube indicate?
an exothermic reaction
What does the hot test tube indicate?
an exothermic reaction
What do chemical symbols indicate?
Chemical symbols indicate elements.
What do you use a chemical indicator for?
to indicate what the chemical is.
What in general terms does a chemical equation indicate?
A chemical equation is the representation of a chemical reaction.
What do scientists do to indicate a chemical change occurrence?
They write a chemical equation.
How will you control the temperature of an endothermic reaction in a mixed reactor?
Studies indicate the best way to control the temperature of the endothermic reaction in a mixed reactor is through making adjustments to the coolant temperature. There processes are highly complex.
The coeficients in a chemical equation indicate?
The coefficients in front indicate the number of actual molecules in the entire formula. This shows a balanced chemical equation.
The chemical formula of a compound does not indicate?
The chemical formula of a compound does not indicate the way that elements are joined in the compound. Chemical formulas tell you the identity of the elements in the compound and the relative proportions of the elements.
What are the four occurrences indicate a chemical reaction has occurred?
A chemical reaction can result in any or all of the following: - a change in temperature (up or down) - a change in color - a smell that wasn't there before - the formation of bubbles (indicating the production of a gas) - the formation of a precipitate
What should not be used to indicate a chemical reaction?
Change of shape can not be used to indicate a chemical reaction has happened. Examples of evidence of a chemical reaction are changes in odor or color.
