Enumerate the four objectives of chemistry?
Explaining the behavior of substances: Chemistry aims to understand the characteristics and properties of substances by studying their composition and structure. Predicting chemical reactions: Chemistry seeks to determine how substances will interact and combine through chemical reactions. Synthesizing new substances: Chemistry involves creating new compounds and materials through various chemical processes. Understanding the natural world: Chemistry helps explain the processes that occur in the natural world, from biological systems to environmental phenomena.
What is the role of equivalent chemistry in determining the reactivity of chemical substances?
Equivalent chemistry plays a crucial role in determining the reactivity of chemical substances by helping to compare the amounts of different substances involved in a chemical reaction. This allows scientists to predict how substances will react with each other based on their equivalent weights, helping to understand and control chemical reactions.
What is the name of a chemical that reacts with another chemical?
A chemical that reacts with another chemical is called a reagent. Reagents are substances used in chemical reactions to bring about a transformation or to detect the presence of other substances.
Chemical change same as chemical reaction?
no because a chemical change is any process in which 1 or more substance is changed into 1 or more substances whereas a chemical reaction is a process that leads to a transformation of one set of chemical substances to another
What is chemical reaction in science?
A chemical reaction is a process in which one or more substances (reactants) are transformed into one or more different substances (products) through the breaking and forming of chemical bonds. This process involves the rearrangement of atoms to create new chemical bonds, resulting in changes in the properties of the substances involved.
Is there chemistry?
Chemistry is the study of chemical composition and structure of substances, also studying chemical reactions and chemical synthesis, etc.
What is chemistry do?
Chemistry is the study of chemical composition and structure of substances, also studying chemical reactions and chemical synthesis, etc.
What is chemistry means?
Chemistry is the study of chemical composition and structure of substances, also studying chemical reactions and chemical synthesis, etc.
Is a chemical reaction?
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.
What are starting substances called?
Starting substances are called reactants in a chemical reaction. Reactants are the substances that are present at the beginning of a chemical reaction and undergo transformation into products.
Substances change after a chemical reaction is called what?
A chemical reaction is the transformation of reactants in products.
Is chemistry mixing chemicals?
Chemistry is much more than mixing materials. Chemistry is the study of chemical composition and structure of substances, also studying chemical reactions and chemical synthesis.
What is the general formula of a chemical equation?
Generally it is REACTANTS ===> Products Symbollically it can be written as A + B = C + D Where 'A' & 'B' are the reactants and 'C' and 'D' are the products, NB All Chemical reactions obey the Law of CONSERVATION of MASS. So the total of the masses on both sides of the equation MUST be equal . This leads to all chemlcal reaction equations MUST be balanced , because each symbol no only represents an element but also represents a mass. ; Different elements have different masses. But overall the tota, ON BOTH sidesL must BE Equal. e.g. 20 g of A + 15 g of B = 30g of 'C' + 5g of 'D'. 20 + 15 = 30 + 5 = 35 Similarly 2NaOH + H2SO4 = Na2SO4 + 2H2O Notice there are 2 sodiums(Na) on both sides (2 x 23 = 46) 6 oxygens on both sides (6 x 16 = 96) 4 hydrogens on both sides ( 4 x 1 = 4) 1 sulphur on both ( 32 x 1 = 32). Since each element has its own atomic mass , the numbers of each element are the same on both sides, then it follows that the total masses are the samer on both sides. Hence the Law of CONSERVATION of MASS is obeyed. S
What is another term for chemical change?
A chemical change is also referred to as a chemical reaction. It typically involves the transformation of substances into new substances with different chemical compositions.
What is the study of the composition of chemical substances and their effects on one another?
Chemistry.
What is the substance used in chemistry?
Substances are used to make chemical reactions.
