Question
Circle the correct response for the fill in the blank. (A(n) element/compound is a pure substance containing two or more elements that are physically/(chemically combined. A(n) element/compound is represented by a chemical symbol/formula. The elements in a(n) element/compound always combine in definite/indefinite proportions. A(n) pure substance/mixture is made of two or more substances that are physically/chemically combined. A mixture that is uniformly mixed is called homogeneous/heterogeneous. A special name for this is a suspension/solution. A mixture that is not uniformly mixed is called homogeneous/heterogeneous. A solid-solid homogeneous mixture is called n colloid/alloy.Explanation / Answer
a) An compound is a pure substance containing two or more elements that are chemically combined. A compound is represented by a chemical formula. The elements in a compound always combine in definite proportions
b) An mixture is made of two or more substances taht are physically combined. A mixture that is uniformly mixed is called homogeneous mixture. A special name for this is called solution. A mixture that is not uniformly mixed is called heterogeneous. A solid-solid homogeneous mixture is called a alloy
