B) land cools off much faster than water (creating a air region of high density above land and lower density above sea)
Chemical properties include reactivity with other elements of substances, toxicity, flammability, and chemical stability
just to name a few
Answer:
Substance is Aluminium
Explanation:
We are given;
Mass; m = 13.5 grams
Volume; V = 5 cm³
Formula for density is;
density = m/V
Density = 13.5/5
Density = 2.7 g/cm³
From the table attached, we can see that the element with a corresponding density of 2.7 is Aluminium
