Answer:
Shared (bonding) electrons : 8
Unshared (lone, non-bonding) electrons : 16
Explanation:
The Lewis dot stricture of the molecule attached to this answer shows us all the valence electrons present in the molecule.
Altogether, we have a total number of 24 valence electrons in SO3.
There are eight electrons shared between atoms of elements, these are the bonding electrons.
There are sixteen electrons that are not shared between atoms of elements, These are the lone or non-bonding electrons.
Hence, there are four shared pairs of electrons and eight pairs of unshared electrons.
Answer : The new pressure acting on a 2.5 L balloon is, 8.6 atm.
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
or,
where,
= initial pressure = 3.7 atm
= final pressure = ?
= initial volume = 5.8 L
= final volume = 2.5 L
Now put all the given values in the above equation, we get:
Thus, the new pressure acting on a 2.5 L balloon is, 8.6 atm.

see explanation
Explanation:
Ice usually has tightly packed molecules at a low temperature. When it comes in contact with a higher temperature or room temperature, the ice molecules gain energy and the molecular tension increases which causes the state to change to liquid. Therefore, a <u>high temperature</u> causes an ice block to melt.
Answer:
argon is 18 2-8-8 since it has octet circle and fully stable you can say it has no electro negativity
An ionic compound is a chemical compound dissociated into positive and negative ions, but globally neutral (it is a bond that usually involves a metal).
A covalent bond is a bond in which two valence electrons are shared between two non-metals (which is often the case in organic substances). In this type of bond, there must be an electronegativity difference of less than 1.7 on the Pauling scale.
Returning to the question, the first question to investigate is if the substance is simple or compound (all of them are compound).
The next question for the substances is if there's a metallic atom or a carbon atom in the substance.
The next investigation is a confirmation, by calculating the electronegativity difference between the atoms in the substances according to Pauli's scale. If it's under 1.7, it's a covalent bond, so a covalent compound. if not it's an ionic bond, so an ionic compound.
