Answer:
sodium ions and chloride ions
chloride ion
sodium ion
Explanation:
Ionic substances are composed of ions. When you dissolve an Ionic substance in water, the ions that compose the substance together with water molecules are present in solution.
Hence, when sodium chloride is dissolved in water, sodium ions and chloride ions are released in solution.
Water has a dipole moment. Hence, the chloride ions are attracted to hydrogen (the positive end of the dipole) while sodium ions are attracted to oxygen (the negative end of the dipole).
This is how the solid is dissolved in water.
1. You could drain off the oil as a supernatant, since oil is less dense than water.
2. You could attempt to evaporate the water since they have different boiling points (212 vs 572 F), and then condense it in a separate container using a distillation unit.
Answer:
Because the distance is too far to count with any other way
Explanation:
297 mol Octane * 16 mol CO2 for each 2 mol Octane is equal to 2380 mol octane (since we only have three significant figures, we cannot express it with exact accuracy). Now, we apply the ideal gas law:
V=nRT/P, or volume equals number of moles times the gas constant times temperature divided by pressure. This means that V=2380*.082*(20+273)/.995=57500 liters. That's a lot of carbon dioxide!
<span>Every
chemical is made up of atoms and each atom has one or more electrons
surrounded its nucleus. The electron emits light after changing from
a high energy state o to a lower energy state which is known as
transition. The color of this light is unique to each element because
each atom of a particular element has a different transition energy.</span>
