Based on the trend in the table, hypothesize what the volume of the sample at 400K would be. a. 247 cm^3
b. 285 cm^3
c. 297 cm^3
d. 400 cm^3

Significant figures are digits read directly from the measuring instrument plus one more digit, which is __ by the observer.

In a modern periodic table, there are seven periods. a period is any horizontal row of the periodic table, and the elements in a period have consecutive atomic numbers. a group is any vertical column in the periodic table, and there are 18 such groups. groups 3–12, also known as the “b” group elements, are called transition metals. groups 1–2 and 13–18, also known as the “a” group elements, are sometimes called the main groups. metals are characterized by malleability, ductility, conductivity, and a tendency to lose electrons. main group metals are found in groups 1 and 2. nonmetallic elements fall on the right-hand side of the periodic table, that is, groups 13–18. nonmetals have the tendency to gain electrons and are generally brittle. they can be solids, liquids, or gasses at room temperature. now, label the areas of the modern periodic table using the above information. drag the appropriate labels to their respective targets.

Areaction in which a, b, and c react to form products is zero order in a, one-half order in b, and second order in c. by what factor does the reaction rate change if the concentration of a is doubled? 1 by what factor does the reaction rate change if the concentration of b is doubled? 1.4 by what factor does the reaction rate change if the concentration of c is doubled? 4
