I have this equation:

m1c∆T1 = Cp(cal)∆T2 + m2c∆T2

I need to manipulate it so I can solve for Cp(cal).

How do I rearrange the equation?

This is my data:

m1 = 10 g

m2 = 10 g

T1 13.5 C

T2 = 5.0 C

c = 4.184 J g-1 C-1

A certain batch of fireflies were observed to “flash” at the rate of 12.1 times per minute at 25°C and at the lower rate of 6.0 times a minute at a temperature of 15°C. Assume that the flashing is the result of an overall chemical reaction that has a single rate limiting step with the highest activation energy. Use this data to estimate the activation energy for this slowest step. You can assume that the concentrations of “reactants” in the fireflies do not depend on temperature.

Using the codon table provided, translate these two almost identical RNA strands into peptide sequences, using the first base of each as the first triplet in a codon.

I. aguuguuaucgaaaacugcgaguaaauauccugagggcgcgaagcaacc

II. aguuguaucgaaaacugcgaguaaauauccugagggcgcgaagcaacc

Notice that the second strand has a point deletion (the u in bold) with respect to the first strand – comment on how this has affected the resulting peptide chain.

A student is running to catch the campus shuttle bus, which is stopped at the bus stop. The student is running at a constant speed of 6 m/s; she can’t run any faster. When the student is still 60 m from the bus, it starts to pull away. The bus moves with a constant acceleration of 0.18 m/s^2. For how much time and how far does the student have to run before she overtakes the bus? And how fast is the bus traveling when she reaches the bus?
