Answer:
A
Explanation:
A formal charge (FC) is the charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity(Wikipedia).
The formal charge on an atom in a molecule reflects the electron count associated with the atom compared to the isolated neutral atom(University of Calgary).
Looking at all the structures listed A-E for SeO2F2, only structure A minimizes the formal charges for each atom in SeO2F2.
Answer:it conduct thermal conductivity because of the heat it holds
Explanation:
Answer:
The Bohr model shows the atom as a central nucleus containing protons and neutrons with the electrons in circular orbitals at specific distances from the nucleus (Figure 1). These orbits form electron shells or energy levels, which are a way of visualizing the number of electrons in the various shells
Answer : The assumptions appears reasonable for the isothermal process is, 
and 
Explanation :
First law of thermodynamic : It states that the energy can not be created or destroyed, it can only change or transfer from one state to another state.
As per first law of thermodynamic,
The expression for internal energy is:
The expression for enthalpy is:
where,
= internal energy
q = heat
w = work done
n = number of moles
= specific heat capacity at constant volume
= specific heat capacity at constant pressure
= change in temperature
As we know that, the term internal energy and enthalpy is the depend on the temperature and the process is isothermal that means at constant temperature.
T = constant
= 0
So, at constant temperature the internal energy and enthalpy is equal to zero. That means,
and
