Problem- The enzyme succinoxidase catalyzes the oxidation of succinate. At 40 degrees the rate of this reaction is 4.83 times as fast as it is at 20 degrees. Determine the activation energy of this reaction.
Here is the problem which I am struggling on, please help me!
Explain a sample of helium gas occupies 1445mL at 721 mmHg. For a gas sample at constant temperature, find out the volume of helium at 745 mmHg.
Limesonte is another form of CaCO3. Sandstone is primarily silica or sand, SiO2. On the basis of observations made in today's experiment, explain a test that would allow you to distinguish between limestone and sandstone.
