Answer:

See explanation

Explanation:

When we look at SO3 we will notice that the compound is trigonal planar and it is symmetric. This means that it has equal charge distribution hence its dipoles cancel out resulting in a zero net dipole moment.

However, COH2 is also trigonal planar but is non-symmetric. Hence, its dipole moments do not cancel out, hence the molecule has a resultant dipole moment and is a polar molecule

4,410 kJ

Explanation:

Gravitational Potential Enegry (GPE) is calculated as;

GPE = m*g*h where;

m = mass (kg)

g = gravity (m/s²)

h = height (meters)

= 90 * 9.8 * 5000

= 4,410,000‬ joules

= 4,410 kJ

When barium reacts with tellurium to form an ionic compound, each metal atom loses electron(s) and each nonmetal atom gains elec

Bess [88]

Answer: The ionic compound formed is $baF_2$ (barium fluoride)

Explanation:

Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.

Taking the metal as barium and non-metal as fluorine.

Barium is the 56th element of the periodic table having electronic configuration of $[Xe]6s^2$

This element will loose 2 electrons and will form $Ba^{2+}$ ion

Fluorine is the 9th element of the periodic table having electronic configuration of $[He]2s^22p^5$

This element will gain 1 electron and will form $F^{-}$ ion

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

Hence, the ionic compound formed is $baF_2$ (barium fluoride)
