Water is a compound because it always has two hydrogen atoms for each oxygen atom. Water can be broken down into simpler substances. Water is a compound because pure water is composed of only H₂O molecules. Each molecule of water is a chemical combination of two hydrogen atoms and one oxygen atom. Water is a type of molecular compound.

$\boxed{~The~Answer~is~B.~}$

Further explanationCompounds are substances composed of two or more different elements chemically combined that can be separated into simpler substances only by chemical reactions. Water, for example, is a compound because pure water is composed of only H₂O molecules. Each molecule of water is a chemical combination of two hydrogen atoms and one oxygen atom.A molecular bond or covalent bond occurs as a result of electrons can be shared between atoms. Molecular compounds have molecular (covalent) bonds.An ionic bond occurs as a result of electrons can be completely removed from one atom and given to another. Ionic compounds have ionic bonds.Examples of other molecular compounds are carbon dioxide (CO₂) and glucose (C₆H₁₂O₆). Each molecule of CO₂ is a chemical combination of two oxygen atoms and one carbon atom. Each molecule of C₆H₁₂O₆ is a chemical combination of six carbon atoms, twelve hydrogen atoms, and six oxygen atoms.Table salt (NaCl) is a compound because it is made from more than one kind of element (Na and Cl), but it is not a molecule because the bond that holds NaCl together is an ionic bond. An electron from the outer shell of sodium is released and taken by chlorine to reach octet conditions on both sides, that is how ionic bonds occur. Thus NaCl is an ionic compound.A diatomic molecule is a molecule made from two atoms of the same type. For example, oxygen gas in the atmosphere is a molecule because it contains molecular bonds. It is not a compound because it is made from atoms of only one element, i.e. oxygen. Another example is hydrogen gas, nitrogen gas, and chlorine gas.Elements are the simplest forms of matter and therefore cannot be broken down into simpler substances by any chemical or physical reactions. Some examples of elements include hydrogen, oxygen, carbon, sodium, iron, and sulfur. Elements can combine with other elements to synthesize compounds.

You have been consulted by the mobile phone company hookup about a new augmented reality product called “brows”. they want to develop an alternative to google glasses, which, you recall, is a proposed new product which plans to superimpose a whole range of wireless google services over the user’s ordinary vision of the world. these appear in little circles and ovals, and let you phone people, take photographs, navigate across cities and inside buildings, find shops and update your social media. brows would do this too, but not be limited to special google services. the user would wear a small cylinder-shaped device designed to fit on top of their existing eyewear (glasses or sunglasses). it would project a reversed image onto the inside of the lenses, the reflection of which would be in focus for the user. instead of voice control, the user would control the device by eye and neck movements, which the device would track. the device would connect via bluetooth to the user’s phone, which would supply most of the computing power and wireless connectivity. hookup also wants to know what existing services would be most in demand, and which would not work well with brows. using your knowledge of augmented reality, wearable technology and interface design, is the project feasible? if not, why not? if feasible, how could the product need to be modified for a better experience?
