500.00g / 89 g/mol = 5.62 moles 1 mole = 1000 millimoles (5.62 moles)(1000 mmol/mole) 5620 millimoles. Are you sure the mass is 500.0 grams? Could it me milligrams?
Moles of Ti = 3.0g / 47.87g/mol = 0.0627 moles Ti 8.0g Cl2 / 70.9g/mol = 0.113 mol Cl2 Available ratio: (0.113 mol Cl2) / (0.0627 moles Ti) = 1.80 mol Cl2 / 1mole Ti Needed Ratio: The Cl2 / Ti mole ratio in the balanced chemical equation = 2 mol Cl2 / 1 mol Ti The comparison ...
The reaction is: C7H8 + Br2 --> C7H7Br + HBr Find the molar masses of C7H8 and of C7H7Br The theoretical yield is: (1.5g C7H8)(mol.mass C7H7Br / mol.mass C7H8)
Unsaturated fats (oils) contain one or more double bonds that are chemically active. That makes them vulnerable to oxidation and to breaking of the long fatty acid chain at the double bond into shorter fatty acid chains. What does this tell you about the relative stability of ...
1. Yes 2. Yes
According to the Law of Conservation of Mass, the total mass before and after a physical or chemical change remains the same.
Bond breaking is an energy absorbing process. The question should read: "What is the amount of energy absorbed when a carbon carbon single bond is broken?" In a spontaneous decomposition, energy is released because of the formation of new, more stable bonds.
The melting point of PbCl2 is about 501 deg C. If the crystals melted, that would account for the increased conductivity. Impurities in the crystals could have lowered the melting point to 500 deg C. easily.

The reaction is: HCl + NaOH --> NaCl + H2O For 100% neutralization, moles NaOH needed is 3.75. For 50% neutralization, you use half of 3.75 millimoles NaOH. At that point, 50% of the HCl is still there. [H+] = conc. of HCl = (moles HCl)/(Total volume)* *Note: Total volume (...
