Answer: BaCO3(s) + 2H+(aq) --> Ba+2 + H2O(l) + CO2(g)

Explanation: Net ionic equations show only the species or atoms that participate in the reaction, in this case gas-forming

When solid barium carbonate is combined with excess aqueous hydroiodic acid the reaction that take place is.

BaCO3(s) + 2HI(aq) --> BaI2 (aq) + H2O(l) + CO2(g)

To write a ionic equation is necesary to separte the species that are dissociated in water (ag) and expresed it as ions showing the charge

BaCO3(s) + 2I-(aq) + 2H+(aq) --> Ba+2 + 2I- (aq) + H2O(l) + CO2(g)

Since I- is present in both sides of the reaction, it's eliminated in the net ionic equation, and the final expression is:

BaCO3(s) + 2H+(aq) --> Ba+2 + H2O(l) + CO2(g)

According to the following reaction, how many moles of chlorine gas are necessary to form 0.739 moles carbon tetrachloride? carb
Ilia_Sergeevich [38]

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
