Answer:
2.956 moles chlorine gas will be produced
Explanation:
Step 1: data given
Number of moles carbon tetrachloride (CCl4) = 0.739 moles
carbon disulfide (s) = CS2(s)
chlorine (g) = Cl2(g)
carbon tetrachloride (l) = CCl4(l)
sulfur dichloride (s) = SCl2 (s)
Step 2: The balanced equation
CS2(s) + 4Cl2(g) → CCl4(l) +2SCl2
Step 3: Calculate moles chlorine gas
For 1 moles Cs2 we need 4 moles Cl2 to produce 1 mol CCl4 and 2 moles SCl2
For 0.739 moles CCl4 we need 4*0.739 = 2.956 moles Cl2
2.956 moles of chlorine gas will be produced

Explanation:
Along the third type of plate boundary, two plates move laterally and pass each other along giant fractures in Earth's crust. Transform faults are so named because they are linked to other types of plate boundaries. The majority of transform faults link the offset segments of oceanic ridges.

Explanation:
The formula for calculating the enthalpy change of a reaction by using the enthalpies of formation of reactants and products is
TiCl₄(g) + 2H₂O(g) ⟶ TiO₂(s) + 4HCl(g)
