It was concluded that different liquids do evaporate at different rates, according to the physical properties of the given substance. Nail polish remover vaporized the quickest, followed by water, salt water, vinegar, orange juice and oil.
Explanation:
An electron cloud is the region of space that surrounds the nucleus of an atom under the nucleus of the negatively charged sub-atomic particles.
- An atoms is made up of some particles.
- The proton is positively charged and it is located in the nucleus of an atom.
- The neutrons do not carry any charges and occupies the nucleus with protons.
- Electrons are the negatively charged particles outside the nucleus.
- The electron cloud is portion of an atom with greatest probability of finding an electron.

The answer is Al.
If it is a main group element with 3 electrons in its Lewis dot structure, it must be in group 3A. If it is in the 3p orbital section, then it must be in period 3, since the p orbital is a valence orbital and the number that preceeds it is the principal quantum number. Therefore, your answer is the element in period 3 and group 3A, which is aluminum.
Answer:
Dna is a molecule. It carries hereditary information. It is located in the chromosomes.
Since the question manages to include moles, pressure, volume, and temperature, then it is evident that in order to find the answer we will have to use the Ideal Gas Equation: PV = nRT (where P = pressure; V = volume; n = number of moles; R = the Universal Constant [0.082 L·atm/mol·K]; and temperature.
First, in order to work out the questions, there is a need to convert the volume to Litres and the temperature to Kelvin based on the equation:
250 mL = 0.250 L
58 °C = 331 K
Also, based on the equation P = nRT ÷ V
⇒ P = (2.48 mol)(0.082 L · atm/mol · K)(331 K) ÷ 0.250 L
⇒ P = (67.31 L · atm) ÷ 0.250 L
⇒ P = 269.25 atm
Thus the pressure exerted by the gas in the container is 269.25 atm.
