Answer. Chemical reaction had occurred and both the powders are different substances.
Explanation:
As density is an intensive property of the substance.Which means that different substance have different densities.
Density = 
Density of powder 1, 
Density of powder 2, 
On comparing both the densities of the powders we can say that both the substances are different. So we can conclude that the chemical reaction had occurred.
Granulated sugar dissolves faster than a sugar cube since it has a higher surface area. A sugar cube has a low surface which takes more time to dissolve.
Answer:
2.0 x 10⁻³ M/s.
Explanation:
- The rate of the reaction is the change of the concentration of the reactants or the products with time.
<em>The rate of the reaction = - Δ[reactants]/Δt = - [(0.6 M - 1.8 M)]/(580 s - 0 s) = 2.069 x 10⁻³ M/s.</em>
That depends. In Celsius, its 0 degrees. In Farenheight, its 32 defrees. In Kelvin, its 273.15 Kelvin.
Ion is an atom or molecule with a net electric charge due to loss or gain of one or more electrons.
