Question 1

What chemical is household bleach?

Answer 1

Sodium Hypochlorite
Household bleach is, in general, a solution containing 3–8% sodium hypochlorite and 0.01–0.05% sodium hydroxide; the sodium hydroxide is used to slow the decomposition of sodium hypochlorite into sodium chloride and sodium chlorate.

Question 2

When was the Ming dynasty?

Answer 2

1368–1644
The Ming dynasty (Chinese: 明朝; pinyin: Míng Cháo), or the Great Ming (Chinese: 大明; pinyin: Dà Míng), also called the Empire of the Great Ming, was the ruling dynasty of China for 276 years (1368–1644) following the collapse of the Mongol-led Yuan dynasty. The Ming, described by some as “one of the greatest eras of orderly government and social stability in human history,”[5] was the last dynasty in China ruled by ethnic Han Chinese. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the Shun dynasty, soon replaced by the Manchu-led Qing dynasty), regimes loyal to the Ming throne – collectively called the Southern Ming – survived until 1662.

Question 4

What are the types of planets?

Question 5

What are the terrestrial planets and what does that mean?

Answer 5

Mercury, Venus, Earth, and Mars
A terrestrial planet, telluric planet or rocky planet is a planet that is composed primarily of silicate rocks or metals. Within the Solar System, the terrestrial planets are the inner planets closest to the Sun, i.e. Mercury, Venus, Earth, and Mars. The terms “terrestrial planet” and “telluric planet” are derived from Latin words for Earth (Terra and Tellus), as these planets are, in terms of composition, “Earth-like”.

Terrestrial planets have a solid planetary surface, making them substantially different from the larger giant planets, which are composed mostly of some combination of hydrogen, helium, and water existing in various physical states.

Question 6

What are the Giant planets and what are their types?

Answer 6

A giant planet is any massive planet. They are usually primarily composed of low-boiling-point materials (gas or ices), rather than rock or other solid matter, but massive solid planets can also exist. There are four giant planets in the Solar System: Jupiter, Saturn, Uranus and Neptune. Many extrasolar giant planets have been identified orbiting other stars.

Giant planets are also sometimes called jovian planets, after Jupiter. They are also sometimes known as gas giants. However, many astronomers apply the latter term only to Jupiter and Saturn, classifying Uranus and Neptune, which have different compositions, as ice giants.[1][2] Both names are potentially misleading: all of the giant planets consist primarily of fluids above their critical points, where distinct gas and liquid phases do not exist. The principal components are hydrogen and helium in the case of Jupiter and Saturn, and water, ammonia and methane in the case of Uranus and Neptune.

Objects large enough to start deuterium fusion (above 13 Jupiter masses in the case of solar composition) are called brown dwarfs, which occupy the mass range between that of large giant planets and the lowest-mass stars.
