Rite an equation for the formation one mole of CaCO3(s) from its elements in their standard states. Write any reference to carbon as C(s). Express your answer as a chemical equation using fractional coefficients as needed. Identify all of the phases in your answer.

The chemical equation for the formation one mole of from its elements in their standard states is

Explanation:

The standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements, with all substances in their standard states.

The chemical equation for the formation one mole of from its elements in their standard states is:

where (s) represents solid state and (g) represents gaseous state.

answer; blank (1); /// (2)///(3)///highblank(4)//low;

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
