It's size
Explanation:
The definition of a dwarf planet is "a celestial body that orbits the sun and has a spherical shape but is not large enough to disturb other objects from its orbit"
Essentially, "dwarf" is an adjective. Just like saying the colour distinguishes a purple planet...
Answer:
1. Ag+ precipitates. 2. Ca2+ precipitates. 3. Co2+ precipitates.
Explanation:
First AgBr is formed which is practically insoluble in water. CaBr2 and CoBr2 are soluble.
Then precipitates CaSO4. CoSO4 is soluble.
And then precipitates Co2(PO4)3 which is insoluble.
Answer:
Explanation:
Bases are the species which furnish hydroxide ions in the solution or is capable of forming bonds with electron deficient species as they are electron rich species. When a base accepts a proton, it changes into a acid which is known as its conjugate acid.
Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations. Only the species which are present in aqueous state dissociate. So, the net ionic equation of aqueous solution of ammonia is shown below as:-
Efficiency is defined as the measure of the amount of work or energy is conserved in a certain process. At all times, in every process, work or energy is always lost or wasted due to certain interference. Not all work given is converted to useful work or energy. Thus , efficiency is calculated by dividing the energy or work output to the energy or work input then the value is multiplied by 100 to express efficiency as percentage.
Efficiency = work output / work input Efficiency = (1540 J / 1600 J) x 100= 96.25%
Thus, the answer is B.
