How many grams of oxygen are needed to react with 4.6 grams of titanium(IV) chloride

1.24g

Explanation:

Given parameters:

Mass of titanium (IV) chloride  = 4.6g

Unknown:

Mass of oxygen  = ?

Solution:

To solve this problem, we need to write the balance reaction equation first;

                TiCl₂   +   O₂    →    TiO₂     +   Cl₂

Now to find the mass of the oxygen gas,

Express the given mass of the known TiCl₂ in moles:

         Number of moles of TiCl₂  =

  Molar mass of TiC₂  = 47.9 + 2(35.5) = 118.9g/mol

    Number of moles of TiCl₂   =   = 0.04mole

From the reaction equation;

        1 mole of TiCl₂  reacted with 1 mole of oxygen gas

       0.04 mole of TiCl₂ will react with 0.04 mole of oxygen gas

Mass of oxygen gas  = number of moles x molar mass

              molar mass of oxygen gas  = 2(16) = 32g/mol

  Mass of oxygen gas  = 0.04 x 32  = 1.24g

chemistry sucks a**

explanation:

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
