Answer:
256 K
Explanation:
Given data
- Ideal gas constant (R): 0.0821 atm.L/mol.K
We can determine the temperature of the gas using the ideal gas equation.
P × V = n × R × T
T = P × V / n × R
T = 4.20 atm × 20.0 L / 4.00 mol × 0.0821 atm.L/mol.K
T = 256 K
<h3><u>Compare and contrast between bonds and molecules of polar and non-polar:</u></h3>
- Non-polar covalent bonds are a type of covalent bond in which a pair of electrons is shared with each other between two atoms.
- Polar covalent bond is a type of covalent bond in which pair of electrons are not equally shared between two atoms. We can also say bonds are polar when one element in a compound is more electronegative than the other.
- The bond shared in the compound of carbon dioxide between carbon and oxygen atoms is non-polar covalent bond whereas the shared in the compound of water between hydrogen and oxygen atom is polar-covalent bond.
- Polar molecules are those molecules where there is an “electronegativity difference between the bonded atoms”.
- For eg: Water - , Ammonia - , Sulfur dioxide - , Hydrogen sulfide - , Ethanol - , etc.
- Non-polar molecules are those molecules sharing equal electrons between “atoms of a diatomic molecule” or large molecule cancel each other.
- For eg: Carbon dioxide - , Benzene - , Carbon tetrachloride - , Methane - , Ethylene - , etc.
A specific heat capacity of 0.135 J·°C⁻¹g⁻¹ means that it takes 0.135 J of energy to <em>change the temperature</em> of 1 g of gold by 1 °C.
