The answer is: B) Spills in your shop and any releases on pavement or outside should be poured down a drain.
Pouring used oil down a drain can cause damege to environment.
Oil is nonpolar substance and does not dissolve in the water (polar molecule), used oil remain existent in the drain and sewer or in the environment.
Small spills create a cumulative effect with significant impact on the environment.
Untended spills inside a shop can spread to an inside drain connected to the storm sewer system and cause floods.
Metals are malleable - they can be bent and shaped. This is because they consist of layers of atoms. These layers can slide over one another when the metal is bent, hammered or pressed.
Answer : The volume of calcium hydroxide is, 32.89 ml
Explanation :
Using neutralization law,
where,
= basicity of an acid = 1
= acidity of a base = 2
= concentration of hydrobromic acid = 0.389 M
= concentration of calcium hydroxide = 0.0887 M
= volume of hydrobromic acid = 15 ml
= volume of calcium hydroxide = ?
Now put all the given values in the above law, we get the volume of calcium hydroxide.
Therefore, the volume of calcium hydroxide is, 32.89 ml
Answer:
Solubility is determined by the molecular or ionic structures of the solute and the solvent, and by the intermolecular forces that hold together the particles of each substance
Explanation:
- Ionic bonds and covalent bonds are sort of intermolecular forces
-State of matter does not hold together the particles of each substance
Answer:
The answer to your question is: letter C
Explanation:
Chemical properties is a change is matter observed due to a chemical reaction.
A) Water is a polar molecule. This is a physical property, there is no chemical reaction. This option is wrong.
B) Water is the universal solvent. This is a physical property of water, there is no change of matter, so this is not a chemical property.
C) Water reacts with group 1 metals. This is an example of a chemical property because metals react with water and matter changes to a new substance, this is the correct answer.
D) Water has a high specific heat capacity. This is a physical property, it is not the correct answer to the question.
