What number of products and reactants are produced by a chemical reaction?
It depends on the reaction. Also, only the products are produced by a chemical reaction; the reactants produce the reaction and are changed in the reaction to the products. (If you have a chemical equation, the number of distinct molecules and/or isolated element symbols on the right side of the equation will show how many distinct products are formed in the reaction.)
A synthesis reaction is a reaction between two compounds in which?
A synthesis reaction forms a new compound from two other separate substances. The new compound is chemically distinct from the substances it was formed from.
What is pericyclic compounds?
may be defined as 1. Concerted reaction that proceed via a cyclic transition state 2. No distinct intermediates in the reaction 3. Bond forming and bond breaking steps are simultaneous but not necessarily synchronous
What is the process of precipitation in chemistry?
The formation of a solid product from reaction of at least two components of a fluid phase. The final fluid phase in which reaction occurs is usually obtained by mixing at least two distinct fluid phases each of which is missing at least one of the necessary components of reaction but which together contain all the required components for the reaction.
What is fire really made of?
Fire is actually a very rapid oxidation process with three products: Heat, Light (the 'fire'), and gases (smoke). Therefor it's not really 'made' of anything...all you're seeing is the light product of the chemical reaction. Hope this helps, --Anonymous Firefighter
Why it is difficult for a fire fighter to hold a hose that ejects large amount of water at high speed?
The third law explains this. The high speed and high pressure at which the water comes out of the hose has a reaction force. If left on the ground the hose will wiggle violently to expend part of this energy. However, if the firefighter holds on to it, he will have to bear the reaction force of the fast moving jet of water
Social reaction theory is also commonly called critical theory?
Actually, social reaction theory and critical theory are distinct concepts within sociology. Social reaction theory emphasizes how societal reactions to deviant behavior can influence an individual's future behavior, while critical theory focuses on critiquing and challenging social structures that perpetuate inequality and injustice. Both theories examine social dynamics, but they have different theoretical foundations and approaches.
What provides power to spacecrafts?
While in earths atmosphere, chemical rocketry provides the propulsion. Once the space craft is aloft and free from earth's gravity, it course and trajectory is powered by chemical reaction directed through nozzles. The internal power is provided by "fuel cell's" which is a different type of chemical reaction that provides a steady flow of electrical power for use in life support ,communications, computers, etc.
How many moles of hydrogen chloride are needed to form 1 mole of lithium?
Lithium can never be formed from hydrogen chloride in a chemical reaction, because lithium, hydrogen, and chlorine are all distinct elements, none of which can be converted any others by chemical means.
What are the advantages of staples over sutures?
A distinct advantage that staples have over sutures is their quick placement--stapling is approximately three to four times faster than suturing. Staples are also associated with a lower risk of infection and tissue reaction than sutures.
What is a fission nuclear reaction?
The primary result of a fission reaction is the conversion of mass to energy. In fission, the nucleus split, either through radioactive decay or as result of being bombarded by other subatomic particles known as neutrons.
What is the difference between normal reaction and abnormal reaction?
Normal reaction happens when the reaction is normal. Abnormal reaction happens when the reaction is abnormal.
