So if string theory can connect both quantum mechanics and physics together, then what does string theory predict this current place in time is? Such as there was a beginning or is this just an infinite series? Quantum mechanics predicts an infinite series and physics predicts that there was a beginning.

THe questions are:
Determine the concentration, Molarity, of Potassium iodide solutionwhere 30.0 mL f the Iodide solution was needed to react completely with 10.0 mL of 0.10M dichromate solution. The balances equation is given below: 3I(-) + Cr2O7(-2) + 14H(+) yields 3I2 + 7H20 +2Cr(+3) and
A 0.0621 M KMnO4 solution was used to titrate a solution containing CaC2O4. If 22.76mL of KMnO4 solution was required to reach the titration endpoint, calculate the number of grams of CaC2O4 in the sample. With the eq: MnO4(-) +C2O4(2-) yields Mn(2+) + CO2
