A

Interpretation Introduction

Interpretation : This is to be explained that zirconium metal is cable of reducing water to form hydrogen gas at standard conditions.

Concept Introduction : Reduction is a process in which metal releases OH ions and form hydrogen gas in the solution at some standard conditions.

B

Interpretation Introduction

Interpretation : A balanced equation for the reduction of water by zirconium needs to be determined.

Concept Introduction : Reduction is a process in which metal releases OH- ions and form hydrogen gas in the solution at some standard conditions.

C

Interpretation Introduction

Interpretation : The value of ξ, ΔG and K for the reduction of water needs to be determined.

Concept Introduction : The cell potential is the difference between anode and cathode potential. The standard free radial energy is the energy of the molecules in the solution.

D

Interpretation Introduction

Interpretation : The mass of the hydrogen produced by the 1000 kg of ore needs to be determined.

Concept Introduction : Reduction is a process in which metal releases OH- ions and form hydrogen gas in the solution at some standard conditions.

E

Interpretation Introduction

Interpretation : The amount of hydrogen which is produced needs to be determined.

Concept Introduction : Reduction is a process in which metal releases OH ions and form hydrogen gas in the solution at some standard conditions.

Dr. Mendel asked his BIOL 260 class what their height was and what their parent's heights were. He plotted that data in the graph below to determine if height was a heritable trait. A. Is height a heritable trait? If yes, what is the heritability value? (2 pts) B. If the phenotypic variation is 30, what is the variation due to additive alleles?

Experiment:  Each team will be provided with 5g of a mixture of acetanilide and salicylic acid. You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below. Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization. Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C Sample C-Cool the third sample in an ice-bath to 0-2 °C Results: weight after recrystalization and melting point temp. A=0.624g,102-115° B=0.765g, 80-105° C=1.135g, 77-108 What is the percent yield of A,B, and C.
