The solute is the part of the solution that dissolves in the second component (usually a fluid). Therefore, for the mentioned solution, the solute is ehyl alcohol since it is the one dissolving in water.
As for the solvent, it is the component in which the solute dissolves. In this case, it is water.
Answer:
An ionic compound whose aqueous solution conducts an electric current is called a(n) electrolyte
Explanation:
Electrolytes are substances that contain anions and cations and is therefore able to conduct the electric current.
For example: NaCl
NaCl → Na⁺ + Cl⁻
Answer:
b) the oxygen atom of one molecule and a hydrogen atom of an adjacent molecule
Explanation:
In a H₂O molecule there are two O-H bonds. The O atom being more electronegative pulls away the shared pair of electron in the covalent bond more towards itself thus O gaining a partial negative charge and H atom getting a partial positive charge. Thus a dipole exists in the O-H bond in the H₂O molecules. Thus in both liquid water and solid ice there is a weak attraction or hydrogen bond between the oxygen atom of one H₂O molecule and a hydrogen atom of an adjacent H₂O molecule.
Answer:
The answer to your question is: pressure is expressed in atmosphers.
Explanation:
Data
R = 0.0821
Ideal gas constant
R = 0.08205 atm l / mol °K
Any substance changes to another substance that means the change of the physical property. Like water (
) has different state which changes as the temperature changes. It remain as liquid in the room temperature, in solid form at or below 0°C and vapor phase on or above 100°C. But in all the stage or phase of the substance the composition of the water i.e. remains. Thus the chemical property remains fixed when a substance change to other substance.
