Answer:
Flammability.
Explanation:
Chemical properties of a substance are properties of a substance that occur in the chemical reactions in which it is involved. These are the basis for the classification of substances, such as metals, halogens, acids, alcohols, alkenes, arenes, etc. A class of substances is characterized by chemical properties common to that group. Differences in the chemical and physical properties of substances allow the substance to be identified, and the components of a mixture of substances to be separated and purified.
The chemical properties of a substance are its chemical stability, reactivity, oxidizability, acidity, bromine number, polymerisability, flammability, toxicity, etc. These can be determined by chemical exposure.

<h2>Steps:</h2>
- Remember that Density = mass/volume, or D = m/v
So firstly, we have to find the volume of the rock. To do this, we need to subtract the volume of water A from the volume of the water B. In this case:
- Water A = 30 mL
- Water B = 40 mL
- 40 mL - 30 mL = 10 mL
<u>The volume of the rock is 10 mL.</u>
Now that we have the volume, we can plug that and the density of the rock into the density equation to solve for the mass.
For this, multiply both sides by 10:
<h2>Answer:</h2>
<u>Rounding to the tenths place, the mass of the rock is 36.8 g, or C.</u>
The correct answer is E. C6H6 is not soluble in water. This is determined by the polarities of these substances. Benzene is a non-polar substance because it has equal number of electrons sharing a bond thus it does not dissolve in water which is a polar substance.
Answer:
Pi bond
Explanation:
Pi bond is the type of covalent bond which results from formation of molecular orbital by the side-to-side overlap of the atomic orbitals along the plane perpendicular to the line which connects nuclei of the two atoms in which the bond is formed. It is denoted by symbol π.
The bond is not symmetrical to the internuclear axis and on rotation the axis, the bond breaks.
