There are 1000 grams in a kg.
To convert g to kg, dovide by 1000.
3.5/1000= 0.0035 kg
Final answer: D
It is crucial to match your units of Pressure, Volume, number of mole, and Temperature with the units of R. If you use the first value of R, which is 0.082057 L atm mol-1K-1, your unit for pressure must be atm, for volume must be liter, for temperature must be Kelvin.
Answer:
KBr: strong ion-ion forces
Explanation:
Ionic compounds are non-molecular species. During melting they require a lot of energy input so that the strong ionic bonds that constitute the electrostatic lattice be disrupted. It thus requires very high temperatures. This is indicative of a very strong ion-ion electrostatic interaction which is typical of ionic bonds and results in high melting points of ionic solids.
Hence, the process of melting an ionic solid needs the addition of a large amount of energy in order to break all of the ionic bonds in the crystal.
On the other hand, Br2 is a covalent molecular specie. Most covalent compound have low melting points since their molecules are mostly held together only by weak van der waals forces.
Answer:
contains only water
Explanation:
Distilled water contains pure water only without any other component. If sea water is distilled, it gives off water at its boiling temperature.
Simple distillation is procedure used to obtain a solvent from a solution. It can be used to separate a mixture of liquids in which the components are at different boiling points.
When sea water is distilled, the solution is boiled in a distillation flask to vaporize the solvent. The vapor is condensed back to liquid using a condenser. The pure liquid is collected in a receiver. The solute impurities remain in the flask.
