Chem 1011 Chapter 2 Questions With Complete Solutions
Dalton's Atomic Theory correct answer: 1. Each element is composed of atoms 2. all atoms of a given element are identical all same in each individual element but no two elements are the same 3. Atoms can not be recreated by a reaction. Atoms can not be created or destroyed (law of conservation of mass) 4. A given compound always has the same relative number of atoms (law of constant proportions) JJ Thompson correct answer: did a series of plum pudding experiments with cathode ray tubes ...

CHEM 1011 Quiz 2 Questions With Complete Solutions
What concentration of phosphate would give you a percent transmittance of 35%? correct answer: To find this we turn %T into an absorbance value, then we plug into the equation A = k * c. We know k from the slope of our line (in this case we will use the sample given 1245) and we calculate A from the %T. We then divide to find C, which is our concentration aka molarity. In this case it comes out to 3.7 x 10⁻⁴ = M. A worker dumps 20 grams of detergent that is 30% by weight phosphate ion in...

For the reaction F2(g) ⇌ 2 F(g), the equilibrium constant at 223 °C is 7.3 x 10-13. If a sample of F2 is heated to 223 °C and allowed to reach equilibrium correct answer: nearly all of F2 will remain unreacted, with a very small amount of F present At equilibrium correct answer: the rate of the forward reaction is equal to the rate of the reverse reaction and the concentration of the reactants and products can be very different For the reaction 2 BrCl(g) ⇌ Br2(g) + Cl2(g), the equi...
