Mixture is a material made up of two or more different substances which are mixed. A mixture refers to the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensionsand colloids.[1][2]
Mixtures are one product of mechanically blending or mixing chemical substances such as elements and compounds, without chemical bonding or other chemical change, so that each ingredient substance retains its own chemical properties and makeup.[3]Despite that there are no chemical changes to its constituents, the physical properties of a mixture, such as its melting point, may differ from those of the components. Some mixtures can be separated into their components by using physical (mechanical or thermal) means. Azeotropes are one kind of mixture that usually pose considerable difficulties regarding the separation processes required to obtain their constituents (physical or chemical processes
Answer:
The atmosphere, I believe.
Explanation:
Answer:
1. I shifts toward products and II shifts toward reactants.
Explanation:
Hello,
In his case, since the reaction I) is endothermic (positive ∆H°) and the reaction II) is exothermic (negative ∆H°):
- In the first case, the energy is understood as a reactant, so if the temperature increases, heat is added so the reaction will shift rightwards (towards products).
- In the second case, the energy is understood as a product, so if the temperature increases, heat is added so the reaction will shift leftwards (towards reactants).
Therefore, the answer is:
1. I shifts toward products and II shifts toward reactants.
Best regards.
Answer:
0.875 moles solute
Explanation:
You can find the moles of the solute using the molality ratio:
Molality = moles solute / mass (kg) solution
After converting the mass to kilograms, you can plug the values into the ratio and simplify to find the moles.
1,000 g = 1 kg
350 g 1 kg
-------------- x --------------- = 0.35 kg solution
1,000 g
Molality = moles solute / mass solution
2.5 m = moles solute / 0.35 kg
0.875 = moles solute
