The lock and key theory suggests that there is a complimentary shaped substrate that will fit exactly into the specific shape of the enzyme's active site. In this case, amalyase is the enzyme and the subs...

There are two possible answers here. 1) Add Tollens reagent - the student would see a silver mirror form in the test tube containing the aldehyde. 2) Add Benedicts reagent - te student would see a brick r...

The answer to this question is the alkane series. You can work this out using the following method: Becuase each carbon must make four bonds to complete it outer shell of electrons, there must be double t...

Using conservation of momentum, m1u1 + m2u2 = m1v1 + m2v2, set m1 = 2kg, m2 = 3kg, u1 = 5m/s, u2 = -4m/s and v1 = -4m/s. Substitute these into the equation to get 25 + 3(-4) = 2*(-4) + 3*v2 10 - ...

To start, the equation to use can be identified as the capactior discharge equation V(t) = V_maxe^-t/RC. From here, we can see that this equation can be solved to give capacitance, and...
