Question on notation

Here, when they write v/(mol s^-1 (kg protein)^-1) is 0.30 for the first row first column, do they mean that the value is 0.30 mol s^-1 (kg protein)^-1 or 0.30/(mol s^-1 (kg protein)^-1)?

Copper (II) Acetate from 5% vinegar + salt, electrochemically

I’m trying to create Copper (II) Acetate crystals, but in these times of Coronavirus it’s difficult to come by hydrogen peroxide. I could be patient, but I’m not, so I’m trying to make it electrochemically. I have 5% vinegar and lots of copper scrap, and an adjustable power supply. Unfortunately I can’t barely get any […]

What exactly is temperature?

I’ve read at many places that temperature is the average kinetic energy of particles present in an object.I just don’t get this intuitively how kinetic energy is connected with temperature?And how is heat connected with temperature then?then what exactly is temperature?All of the description given online is very confusing.please help!!!

What is “dithreitol”?

The article by Hu et al. [1] mentions a compound “dithreitol” in the Saliva Proteome Analysis section (emphasis mine): For the “shotgun” approach, saliva samples (1 mL) were pre-fractionated with the use of Millipore ultracentrifuge filters (Millipore Corp., Billerica, MA, USA). Individual fractions were treated with 10 mM dithreitol for 30 min and then 50 […]

Comparing bond angle

How can I compare bond angle between hydrogen sulfide, $\ce{H2S}$, and sulfur dioxide, $\ce{SO2}$? In $\ce{H2S}$ there are 2 lone pairs whereas in $\ce{SO2}$ there is 1 lone pair which means bond angle in $\ce{SO2}$ should be larger but the reverse is true. Also oxygen is more electronegative than hydrogen which means it has less […]

Comparison of lattice energy

Which compound has largest amount of lattice energy among Alf3 and AlN. I think it should be alf3 because lattice energy in inversely proportional to radius and size of flourine is quite small as compared to nitrogen . Talking about charge then both have charge of magnitude 3 but my textbook says AlN has higher […]
