True
Is it true that in a relation for each element of the domain there is only one corresponding element in the range
No, this is false.
False
False. A molecule is the smallest part of a compound that can still be indentified as a compound as it may contain several atoms of different elements. A single atom can only identify a single element, not a compound which it may have been a part of.
No, none of them contains only one element of art.
false a compound is made up of two or more elements.
False. A compound by definition is a substance made up of two or more different elements chemically bonded together. An element, on the other hand, is a pure substance made up of only one type of atom.
No. This is a definition of an atom. Electrons are only part of atoms.
An element is only a chemical element, only a single type of atoms.A compound contain 2 or more atoms of different atoms.Matter can be an element, a compound or a mixture of compounds.
Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.) P True True False False Q True False True False (PVQ) True True True False ~(PVQ) False False False True ~(PVQ)-->P True True True False if it's ~(P^Q) -->P then it's, P True True False False Q True False True False (P^Q) True False False False ~(P^Q) False True True True ~(P^Q)-->P True True False False
Hydrocarbons are not an element, they are a type of compound. They are composed of only hydrogen and carbon atoms.
False
Only True
Iron is the major element in steel. Only an element can be an element, and an element can not be a compound, the definition of which requires more than one element.
False.
