Newton’s second law can be written using two formulas, what are they?

In equation form, Newton's second law of motion is a=Fnetm a = F net m . This is often written in the more familiar form: Fnet = ma. The weight w of an object is defined as the force of gravity acting on an object of mass m. ... Friction is a force that opposes the motion past each other of objects that are touching.

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
