Idk you didn't be very specific
Answer:
Gravitational potential energy may be converted to other forms of energy, such as kinetic energy. If we release the mass, gravitational force will do an amount of work equal to mgh on it, thereby increasing its kinetic energy by that same amount (by the work-energy theorem).
Explanation:
Answer:
Mg(ClO₃)₂ ⟶ MgCl₂ + 3O₂
Explanation:
The reaction gives magnesium chloride and oxygen.
The balanced equation is then
Mg(ClO₃)₂ ⟶ MgCl₂ + 3O₂
A is <em>wrong</em>, because it is not balanced (12 O atoms on left and 6 O atoms on right).
C and D are <em>wrong</em> because they have the reactants as products and vice versa.
Answer:
Chromatography is a method of separation of materials from a mixture. Paper chromatography is a technique of separation where, paper used as a stationary phase and solvent used to separate the sample used as a mobile phase. The sample is applied over the paper in small quantity. The components of the sample separates in a chromatographic paper due to the movement of solvent. The components of the sample moves with the solvent.
Paper chromatography is a useful technique for ink analysis. Ink consists of several dyes, which can be separated individually. When the ink is exposed to certain solvent mixtures the dyes of the ink dissolves in the mixture. Each ink components acquire distinct distance according to the retention factor. Some inks are water soluble, so the solvent used for separation should be water. Inks which are not water soluble are soluble in other solvents like alcohol.
Hydrocarbons are chains of C and H. C and H are held together by covalent bonds.
hydrocarbons are of three main types
alkanes - only single bonds between C atoms
alkenes - double bonds between C atoms present
alkynes - triples bonds between C atoms present
saturated hydrocarbons definition is when there are only single bonds present
from the given compounds
propane - only single bonds
propene - double bond
propyne - triple bond
propanal - double bond between C and O
only compound with single bonds is propane
answer is propane
