which is not true about the chemical formula of a sbstance?
a.it gives the number and kinds of atoms present.
b.it shows that a substance has a definite compound.
c.it shows the elements present in the compound.
d.it shows the phase of a substance.
Yes
True. Chemical properties are characteristics that can only be observed when a substance undergoes a chemical change, such as reactivity with other substances or the ability to undergo a chemical reaction.
There is no chemical formula for an acorn. An acorn is a heterogeneous mixture. Chemical formulas are only used for pure substances, that is compounds and elements.
The chemical formula of sodium hydroxide is NaOH. The chemical formula of ammonium chloride is NH4Cl. Any reaction between these substances in water solution.
No, H1.9O1.9 is not a valid chemical formula as it implies fractional atoms which is not possible in formula representation. A chemical formula should represent whole numbers of atoms for each element.
Not necessarily. Alloys are "substances", but they don't generally have a chemical formula, they're mixtures which are not necessarily in stoichiometric proportions. The same is true for any mixture in general.
The general formula of a chemical equation is: Reactants → Products It represents the transformation of reactant substances into product substances during a chemical reaction.
Yes, after a chemical reaction new substances are formed.
The chemical formula of Aripiprazole is C23H27Cl2N3O2.
true
chemical change
No, in a chemical change new substances are formed with different chemical properties compared to the original substances.
it is not true it is a chemical reaction
Not all chemical formulas represent a compound. Chemical formulas that contain two or more elements represent a compound. Chemical formulas can also represent diatomic molecules, such as H2 or O2. Sulfur is represented by the formula S8.
Yes
N2 is nitrogen gas but technically its dinitrogen
The lines in a structural formula represent the chemical bonds. These bonds are attractive forces between atoms that allow the formation of chemical substances.
