Pure substances are further broken down into elements and compounds. Mixture are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.
Scientists can measure the height in
different units but problem could arise when they compare all the measurements.
That is the reason there is standard units for measurements.
<span>There may be error arises when an
American scientist is measuring the height of an object in inches and other Australian
scientist is measuring the height of same object in meters. Their data cannot
be compared because they are using different units to measure height.</span>
Both create energy. Both require atoms.
Fission is ripping the atoms apart, fusion is forcing them together. Fission takes less energy because it's easier to rip unstable atoms apart but pushing two atoms that have similar charges together is extremely hard. Fission is currently mainstream on earth, but fusion is known for taking place within stars.
Answer:
there are 18 electrons in the outermost shell of argon atom
Answer:
The high system pressure and relatively large chlorine molecule size.
Explanation:
Having the expression of the ideal gas, and clearing the pressure, we have:
P = nRT/V
Meanwhile, for a non-ideal gas we have the following equation:
P = (nRT / V-nb) - n2a/V2
In this equation, high pressures and low temperatures have an influence on nonideal gases.
Therefore, at high pressures, the molecules in a gas are closer together and have high intermolecular forces. On the other hand, at low temperatures, the kinetic energy of a gas is reduced, so that the intermolecular attractive forces are also reduced.
