Explanation:
Making a list of chemical and physical properties of different substances, will makes the study of these substances easier. The physical properties like mass density volume of a substance helps in measuring and knowing the amount of substance taken for a certain use.
While Enlisting the chemical properties of certain substances we see which two substances can be mixed or are allowed to react to get some required substance just by looking at the list without performing a sample reaction to check every time.
Answer:
It is not "strong acids have a low pH"
Explanation:
I feel it should because that is a true statement but for Primavera it is wrong.
Calcium is in group IIA in the periodic table. A Ca ion has a charge of 2+. In order to solve this problem you can either see the periodic table or just look for the charge of the elemetns they give you.
K is group IA - charge of 2+
Magnesium IIA - charge 2+
Bromine VIIA charge of 1-
Scandium IB
The answer is B
Answer:
The independent variable is the type of material
The dependent variable is the thermal energy transferred by that material
Explanation:
The type of material is independent of the heat flowing through it. While the thermal energy transferred is surely dependent on the material through which it transfers.
