"Izzo (H.O.V.A.)" (often referred to as "H to the Izzo") is the first single released by Jay-Z from his sixth album The Blueprint. It is among his most popular singles. This was the second song released off The Blueprint, after the diss track "Takeover", but the lead single from it. The song reached #8 on the Billboard Hot 100 in the U.S. It was Jay-Z's first top 10 single as a lead artist.

The song, produced by Kanye West, prominently features a sample of "I Want You Back" by The Jackson 5, the second major hit in 2001 to sample that song (after "My Baby" by Lil' Romeo).

The music video takes place in New York City with Jay-Z, Damon Dash, Biggs, & other affiliates on a Roc-A-Fella parade float which features cameo appearances from Kanye West, Destiny's Child, Trina, Eve, Nelly, and OutKast.

The song was later mashed up with Linkin Park's "In the End" for their collaborative EP, Collision Course.

Lyrics

The first verse deals with the rapper's early career as a drug dealer, including his escape from conviction. The second verse narrates his struggles with the exploitative recording industry, while in the last verse he reverts to his childhood growing up in the Marcy Houses housing projects.

The Victoria and Albert Museum (often abbreviated as the V&A), London, is the world's largest museum of decorative arts and design, housing a permanent collection of over 4.5 million objects. It was founded in 1852 and named after Queen Victoria and Prince Albert. The V&A is located in the Brompton district of the Royal Borough of Kensington and Chelsea, in an area that has become known as "Albertopolis" because of its association with Prince Albert, the Albert Memorial and the major cultural institutions with which he was associated. These include the Natural History Museum, the Science Museum and the Royal Albert Hall. The museum is a non-departmental public body sponsored by the Department for Culture, Media and Sport. Like other national British museums, entrance to the museum has been free since 2001.

The V&A covers 12.5 acres (51,000 m²) and 145 galleries. Its collection spans 5,000 years of art, from ancient times to the present day, from the cultures of Europe, North America, Asia and North Africa. The holdings of ceramics, glass, textiles, costumes, silver, ironwork, jewellery, furniture, medieval objects, sculpture, prints and printmaking, drawings and photographs are among the largest and most comprehensive in the world. The museum owns the world's largest collection of post-classical sculpture, with the holdings of Italian Renaissance items being the largest outside Italy. The departments of Asia include art from South Asia, China, Japan, Korea and the Islamic world. The East Asian collections are among the best in Europe, with particular strengths in ceramics and metalwork, while the Islamic collection is amongst the largest in the Western world.

The V-2 (German: Vergeltungswaffe 2, "Retribution Weapon 2"), technical name Aggregat-4 (A-4), was the world's first long-rangeguided ballistic missile. The missile with a liquid-propellant rocket engine was developed during the Second World War in Germany as a "vengeance weapon", designed to attack Allied cities as retaliation for the Allied bombings against German cities. The V-2 rocket also became the first artificial object to cross the boundary of space with the vertical launch of V-177 on 20 June 1944.

Beginning in September 1944, over 3,000 V-2s were launched by the German Wehrmacht against Allied targets during the war, first London and later Antwerp and Liège. According to a 2011 BBC documentary, the attacks resulted in the deaths of an estimated 9,000 civilians and military personnel, while 12,000 forced laborers and concentration camp prisoners were killed producing the weapons.

As Germany collapsed, teams from the Allied forces—the U.S., Great Britain and the Soviet Union—raced to capture key German manufacturing sites, guided missiles, rockets and jet powered aircraft. Wernher von Braun and over 100 key V-2 personnel surrendered to the Americans. Through a lengthy sequence of events, a significant portion of the original V-2 team ended up working for the US Army at the Redstone Arsenal. The US also captured enough V-2 hardware to build approximately 80 of the missiles. The Soviets gained possession of the V-2 manufacturing facilities after the war and proceeded to re-establish V-2 production and move it to the Soviet Union.

Oxybenzone or benzophenone-3 (trade names Milestab 9, Eusolex 4360, Escalol 567, KAHSCREEN BZ-3) is an organic compound. It is a white solid that is readily soluble in most organic solvents. Oxybenzone belongs to the class of aromatic ketones known as benzophenones. It is a component of many sunscreen lotions.

Structure and electronic structure

Being a conjugated molecule, oxybenzone absorbs at lower energies than many aromatic molecules. As in related compounds, the hydroxyl group is hydrogen bonded to the ketone. This interaction contributes to oxybenzone's light-absorption properties. At low temperatures, however, it is possible to observe both the phosphorescence and the triplet-triplet absorption spectrum. At 175 K the triplet lifetime is 24 ns. The short lifetime has been attributed to a fast intramolecular hydrogen transfer between the oxygen of the C=O and the OH.

Production

Oxybenzone is produced by Friedel-Crafts reaction of benzoyl chloride with 3-methoxyphenol(3-hydroxyanisole).

Water (H
2O) is the most abundant compound on Earth's surface, covering 70 percent of the planet. In nature, water exists in liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at standard temperature and pressure. At room temperature, it is a tasteless and odorless liquid, nearly colorless with a hint of blue. Many substances dissolve in water and it is commonly referred to as the universal solvent. Because of this, water in nature and in use is rarely pure and some properties may vary from those of the pure substance. However, there are also many compounds that are essentially, if not completely, insoluble in water. Water is the only common substance found naturally in all three common states of matter and it is essential for all life on Earth. Water makes up 55% to 78% of the human body.
