• Add this info to your notes that you took from the last section. • Compound- A substance composed of two or more elements that are chemically bonded to form a new substance with different properties. • Example 1- Water. Water’s chemical formula is H2O. • Mixture- a combinati...
A substance that has a non-uniform composition throughout the bulk is a heterogeneous substance. It has more than one phase. For example, a mixture of salt in water forms a non-homogeneous solution if not mixed thoroughly. If we take out 1mL of this solution from any side, it will not...

A molecule may consist of atoms of a single chemical element, as with oxygen (O2), or of different elements, as with water (H2O). A chemical element is a pure chemical substance consisting of one type of atom distinguished by its atomic number, which is the number of protons in its ...
How to convert grams of water to milliliters with a formula How much does a 100 ml beaker weigh? What is the mass in grams of a single molecule of water, H2O? What is the mass of a 15 mL sample of mercury? A substance has a density of 4.5 g/mL. What is this in kg/L?
Engineering. Consider the example of HNO2 reacting with H2O. Is HNO2 strong or weak? [Quick overview], Is SiCl2F2 Polar or Nonpolar? On the flip side, a 0.0005 M HCl solution is dilute, yet still strong. Conjugate acid is an acid that formed when the parent base compound gains one ...
Its vapor can form explosive mixture with air. Its explosion limit is 2.0% to 12% (by volume). It belongs to a moderate explosive hazardous material and flammable, low toxic substance. The toxicity of its vapors is twice as high as ethanol while oral administration causes the opposite ...
The structure of Camphor is shown below. Based on this structure, it has a large hydrocarbon moiety and single carbonyl oxygen. Due to the large... Learn more about this topic: Solubility in Chemistry | Definition, Units & Factors from ...
Is sodium classified as a pure substance (element or compound) or a mixture? Explain. Define the term molecule in details. Also, explain its appearance and characteristics. Can sodium chloride and water be used to make a buffer? Explain. ...
