When TiCl4 (s) reacts with H20 (), the products TiO2 (s) and HCl (g) are formed. If there is 87.3 g of titanium (IV) chloride present, with water in excess, how much solid titanium (IV) oxide (in grams)
could theoretically be produced?

The mass of titanium (IV) oxide produced is 36.7 grams.

Given:

The reaction between titanium (IV) chloride and water.

The mass of titanium (IV) chloride is 87.3 g.

To find:

The mass of titanium (IV) oxide produced.

Solution:

The mass of titanium (IV) chloride = 87.3 g.

Moles of titanium (IV) chloride =

According to reaction, 1 mole of titanium (IV) chloride gives 1 mole of titanium (IV) oxide, then 0.460 moles of titanium (IV) chloride will give:

Mass of 0.460 moles of  titanium (IV) oxide:

The mass of titanium (IV) oxide produced is 36.7 grams.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
