Also where did you get the number 37?

Math
Ok thanks Why plus one added?

What is the final daughter nuclide for 131I ? How is it determined?

chemistry
We have not even covered this material. Samples of 131I take 10 hours to prepare to ship. It takes 2 weeks to get to its destination. How much 131I must be produced to ensure the patient receives 8 grams of NaI using the 131I isotope in the compound? Does this have to do with ...

What is the complete decay series for 241 Am: show every alpha, beta and gamma decay product. What is the reason for beta and gamma products to be in the alpha chain?

Statistics
As the degrees of freedom for the t-distribution increase, the distribution approaches the value of zero for the mean. the t-distribution. the normal distribution. the F distribution.

Statistics
When finding a confidence interval for a population mean based on a sample of size 11, which assumption is made? The standard deviation is fixed. The sampling distribution of z is normal. The sampling distribution of the sample means is approximately normal. There is no ...

Physics
Which of the following statements is not true about refraction? Refraction occurs when light's velocity changes. The angle between the refracted ray and the normal is called the angle of refraction. When light moves from a rarer to a denser medium, it bends toward the ...

Is this equation correctly balanced? If not why. Al2S3+H2O----> Al2S3+3H2O---->Al2(SO)3+3H2

I thought about the syntax of the problem and I have surmised that what I thought were two questions was actually one. I'm slow but not dead yet. 75g of tartaric acid in 1 liter is used in a titration. 25mL of tartaric acid solution is titrated against 31mL of NH4OH. What ...

DrBobb222, I think he is screwing with us. This titration business is eight chapters ahead on our syllabus. Perhaps he wants us to tell him what is needed to complete the process?

chemistry
I left out part of my question. This may make better sense. But I'm not sure of what he can be asking me to do with it. 75g of tartaric acid in one liter is used in a titration. What could he want me to find?

chemistry
I don't know what he wants me to do with this. This is for extra credit and for good reason. It is way ahead of where we are in the text. This is all the information given. 75g of tartaric acid is used in a titration. What do I do with that?
