when doing a flame test: the hydrated salt is overheated and the anhydrous salt thermally decompose, one product being a gas; will the reported value of x be too high, too low on the unaffected?

Why can't the Ka for HCl be obtained from a titration curve like that of acetic acid?

a)For the titration of an acid analyte with a NaOH titrant, a phenolphthalein endpoint will change from colorless to pink. If the "pink" resulted from perhaps only a half-drop(or less) of NaOH titrant and the Erlenmeyer flask is set aside on the laborator...

Two point charges Q1 and Q2, are located a distance .20 meter apart, as shown above. Charge Q1 = +8.0μC. The net electric field is zero at point P, located .40 meter from Q1 and .20 meter from Q2. Determine the magnitude and sign of charge Q2.

I need help with solving two system of equations using the echelon method.

Ok maybe I didn't understand the question, I guess it doesn't, I just assumed it was a flame test

For HCl I got between 3.48 and 5.68 And for CH3COOH I got between 6.20 and 7.16

The first and second answer were incorrect the answer to question one was 46, and the answer to question three was 48.5. But good job for trying. :)

ok so this is simple but its worded weird. Basically subtract the ball's speed by Lisa's speed. (49-13)=39. You're answer is 39 mph

Sorry i meant 36

I think you just divide the original by 2-

just two, not negitive two

I think d is correct
