Barium hydroxide is a chemical compound with the chemical formula Ba(OH)₂ₓ. The monohydrate, known as baryta or baryta-water, is one of the principal compounds of barium.
Answer:
The correct answer is "Increased energy enables more particles to collide."
Explanation:
The reaction rate is defined as the change in the concentration of one of the reagents or products, in a time interval in which the change takes place.
For a chemical reaction to take place, the molecules of the reagents must collide, and must also collide effectively. In other words, these shocks must be produced with sufficient energy so that they can break and form chemical bonds. In the crash there must be proper orientation.
When increasing the temperature, the molecules will possess greater kinetic energy, which is that energy related to the movement of the molecules. Consequently, these molecules will move faster.Thus, the possibility of colliding with another molecule increases significantly. In this way, the reaction rate increases.
So, <u><em>the correct answer is "Increased energy enables more particles to collide."</em></u>
The change that would need to be made to the slit spacing in order to see a diffraction pattern is bending, because in understanding why light behaves like a wave, it is the interference and diffraction were the phenomena distinguish waves from particles but waves are the only one can interfere and diffract while particles do not. The light bends around obstacles or cylinder like waves do, then it is bending which cause and resulted in the single slit diffraction pattern.
Answer:
Tree sap flows over the leaf and preserves it.
Explanation:
Amber would preserve the image.
Moles = (6.74*10^23)/(6.02*10^23) =1.119 moles
1.119*44.09=49.36g
