What is the name of compound generator?
Compound Wound DC Generator In shunt wound generators, the output voltage is inversely proportional with load current. A combination of these two types of generators can overcome the disadvantages of both. This combination of windings is called compound wound DC generator.
How do you come up with a chemical name?
Molecular compounds are named with the first element first and then the second element by using the stem of the element name plus the suffix -ide. Numerical prefixes are used to specify the number of atoms in a molecule.
What is the compound name of mgcl2?
Magnesium dichlorideMagnesium chloride / IUPAC ID
What chemical are used in fireworks?
Explosions: gunpowder – the explosions in most fireworks still use traditional gunpowder, composed of potassium nitrate (saltpeter), sulfur, and charcoal. Potassium is largely imported from Canada, though some is mined in New Mexico and Utah.
What are the chemical compounds used in fireworks?
Metal salts commonly used in firework displays include: strontium carbonate (red fireworks), calcium chloride (orange fireworks), sodium nitrate (yellow fireworks), barium chloride (green fireworks) and copper chloride (blue fireworks).
What is level compound generator?
A level compound generator is when the terminal voltage at rated current is the same as the one at no load condition. It is called an over compound generator if the terminal voltage is more than the rated current.
What are the types of compound generator?
There are two types of compound wound generators, the series field winding and the shunt field winding. There are two windings, one in series with the armature and the other in parallel with it. There are two types of DC generators- short and long compound-wound.
What is the name of this compound NH4Br?
Ammonium bromide, NH4Br, is the ammonium salt of hydrobromic acid. The chemical crystallizes in colorless prisms, possessing a saline taste; it sublimes on heating and is easily soluble in water.
What is the name for the compound with the formula Ba3N2?
Barium nitride (Ba3N2)
What is the chemical name of the compound CuOH?
Copper(I) hydroxide is the hydroxide of the metal copper with the chemical formula of CuOH. It is a mild, highly unstable alkali. The color of pure CuOH is yellow or orange-yellow, but it usually appears rather dark red because of impurities.
What is Cu(OH)2 – copper hydroxide?
Cu (OH)2 – Copper Hydroxide What is Copper Hydroxide? Copper hydroxide is also called cupric hydroxide is a pale blue precipitate produced when sodium or potassium hydroxide is added in excess to a solution of a copper salt. Copper hydroxide is crystalline but inert compound used in the preparation of a wide variety of salts.
How do you name CU and Oh on the periodic table?
Name the for Cu as it appears on the Periodic Table. Use the Common Ion Table to find the formula and charge for OH. Look at the chemical formula to find the charge for Cu. The polyatomic ion has a charge of -1 (OH – ). We have two polyatomic ions so Cu will have a charge of +2. To show that we write (II) after the name for Cu.
What is the name of the precipitate formed when copper hydroxide is added?
Copper hydroxide is also called cupric hydroxide is a pale blue precipitate produced when sodium or potassium hydroxide is added in excess to a solution of a copper salt. Copper hydroxide is crystalline but inert compound used in the preparation of a wide variety of salts.
