Why is it not possible to achieve 100% yield in a chemical reaction {Ans: It is not possible to achieve 100% yield in a chemical reaction as some of the product may be lost and the reactants may react in differently way so we don't get the product expected, reversible reactions may not go to completion}Describe the structure of fullerenes {Ans: Fullerenes are molecules of carbon atoms with hollow shapes they have hexagonal rings of carbon atoms, however they can also have rings with five or seven carbon atoms}What is the word equation for the reaction of group 1 metals and water? {Ans: Metal + Water → Metal Hydroxide + Hydrogen}What is atom economy? {Ans: Atom economy is a measure of the amount of starting materials that end up as useful products}Is graphite a good or bad conductor of heat and electricity? {Ans: Graphite is a good conductor heat and electricity}What is reduction? {Ans: Reduction is gain of electrons}What are the properties of ionic compounds {Ans: The properties of ionic compounds are that they can transfer electrons when they react, they have high melting and boiling points and can conduct electricity when they
