Just need these last few checked:

6. Elements in a group on the periodic table have similar properties. -False?

7. Nonmetals are ductile materials.- False?

11. Matter can be created or destroyed using common chemical changes.- True?

13. 346.7500 has five significant figures.- True?

23. Scientific laws can change.- False?

28. 0.00036 is the same as 3.6 x 10^4.- False?

36. One liter equals 1000 cm^3.- True?

Thanks

YOu fail. 6, 11, 13, 23, are all wrong. I do not like true/false questions.

6. Elements in a group on the periodic table have similar properties. - False?

To check this statement, we can refer to the periodic table. Groups on the periodic table are the vertical columns. Elements within the same group tend to have similar properties because they have the same number of valence electrons. Therefore, we can conclude that the given statement is true.

7. Nonmetals are ductile materials. - False?

To verify this statement, we need to understand the properties of nonmetals. Nonmetals are typically not ductile, meaning they cannot be drawn into thin wires. Ductility is a characteristic of metals, not nonmetals. As a result, we can conclude that the given statement is true.

11. Matter can be created or destroyed using common chemical changes. - True?

According to the Law of Conservation of Mass, matter cannot be created or destroyed in a chemical reaction. It can only be transformed or rearranged. Therefore, the given statement is false.

13. 346.7500 has five significant figures. - True?

To determine the number of significant figures in a decimal number, we need to consider each digit. Significant figures are all non-zero digits and any zeros between them. In this case, all of the digits (3, 4, 6, 7, and 5) are non-zero, and the zeros between them are also significant. Thus, there are five significant figures in the number 346.7500, so the statement is true.

23. Scientific laws can change. - False?

Scientific laws are fundamental principles or relationships in science that have been repeatedly tested and proven to be true. They are based on extensive evidence and are considered to be consistent and unchanging. Therefore, scientific laws do not change, so the given statement is false.

28. 0.00036 is the same as 3.6 x 10^4. - False?

To compare the given values, we need to convert 0.00036 to scientific notation. Writing 0.00036 in scientific notation, we would have 3.6 x 10^(-4) since the decimal point needs to be moved four places to the right from its original position. Therefore, the given statement is false.

36. One liter equals 1000 cm^3. - True?

To convert between liters (L) and cubic centimeters (cm^3), we need to know the conversion factor, which is 1 L = 1000 cm^3. This conversion is a fundamental unit conversion in the metric system, so the given statement is true.
