17) large amounts of very important metal titanium are made by reacting magnesium metal with titanium tetrachloride. titanium metal and magnesium chloride are produced. a) write the balanced equation for this reaction. b) how many kilograms of magnesium are required to produce 1.00 kilograms of titanium? ( show work, .)

a) 2Mg + TiCl₄ ⟶ 2MgCl₂ + Ti

b) 1.02 kg

Step-by-step explanation:

a) Balanced equation

We know we will need a balanced equation with masses and molar masses, so let’s gather all the information in one place.  

M_r:    24.30                                 47.87

           2Mg + TiCl₄ ⟶ 2MgCl₂ + Ti

m/kg:                                              1.00

b) Mass of Mg

(i) Calculate the moles of Ti

n = 1.00 kg Ti  × (1 kmol Ti /47.87 kg Ti)

 = 0.020 89 kmol Ti

(ii) Calculate the moles of Mg

The molar ratio is (2 kmol Mg/1 kmol Ti)

n = 0.020 89 kmol Ti × (2 kmol Mg/1 kmol Ti)

  = 0.041 78 kmol Mg

(iii) Calculate the mass of Mg

m = 0.041 78 kmol Mg × (24.30 kg Mg/1 kmol Mg)

   = 1.02 kg Mg

You need 1.02 kg Mg to produce 1.00 kg Ti.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

i'm wiling to try and you : )
