The answer to this question is yes i think
NACL, or salt, is an ionic compound made up of a cation from a base and an anion from an acid. (Water being the base.) Your answer would be the last option, "Formed due to reaction of acid with water."
Answer:
No precipitate will form on mixing potassium bromide and lead acetate
Explanation:
Precipitation occurs when the ionic product of the ions exceeds the solubility product of the corresponding salt in the solution. If, this implies that the solution is over saturated and precipitation of salt will occur.Potassium bromide and lead acetate are strong electrolyte and thus completely dissociate in water.
The dissociation reaction is given as,Potassium bromide and lead acetate react to give lead bromide and potassium acetate.The concentration of lead ions is equal to the concentration of.The concentration of bromide ion is equal to the concentration of.Potassium acetate is soluble in aqueous solution. Lead bromide will precipitate out if the ionic product of lead ion and bromide ion exceeds the solubility product of .
The value of solubility product constant,, for is.The reaction quotient for is calculated as,Substitute the values.The value of the reaction quotient for is less than its solubility product, , therefore, precipitation of will not occur.
Answer:
Explanation: k =10^3, m =10^-3
2.8 Kg = 2.8 *10^3 g
To conver kg to mg you need to
=2.8* 10^3 *10^-3* 10^3
=2.8 * 10^6 *10^-3
= 2.8 * 10^6 mg
The energy (a) in EV and (b) in joules of the third energy level (n= 3) of the hydrogen atom.
-1.51 eV
-2.42 x 10^-19 J
In physics, energy is a quantitative property that is transferred to a body or physical system and can be perceived in the performance of work or in the form of heat and light. Energy is Conserved - The law of conservation of energy states that energy can be transformed into form, but cannot be created or destroyed.
Energy, in physics the ability to do work. It can exist in electrical, kinetic, thermal, electrical, chemical, nuclear, or various other forms. There is also heat and work. H. Energy in transfer from one object to another. Ability or power to do work. B. The ability to move an object (of a certain mass) by applying a force. Energy exists in many forms, such as electrical, mechanical, chemical, thermal, and nuclear, and can be transformed from one form to another.
