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
P(total)=P1+P2+P3+...
P(total)=P(N2)+P(others)+P(O2)
100kPa=78kPa+1kPa+P(O2)
P(O2)=100-79=21kPa

Answer: The results agree with the law of conservation of mass
Explanation:
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. On the reactant side, the total mass of reactants is 14.3g and the total product masses is also 14.3g. That implies that no mass was !most in the reaction. The sum of masses on the left hand side corresponds with sum of masses on the right hand side of the reaction equation.
chemical. During the process of digestion, the food is broken down into smaller molecules. The salivary glands present in our mouth helps in the breakdown of the food. In this process, there is a formation of a new substance. Therefore, it is considered to be a chemical change.
