I know about red, orange, yellow, blue and white flames, but I've recently heard of black flames. My dad says fire can reach a temperature at which the flames can turn black, but it's too intense for humans to be near. Is this true?

Thanks in advance. I'll award 10 pts to whoever gets it right first!!


How many milliliters of 0.150 M NaOH is needed to react completely with 3.45 g iodine according to the equation:

3 I2 + 6NaOH --> 5NaI + NaIO3 + 3H2O?


How many grams of oxygen are needed to burn 56.92 g of C10H22


Hydrazine, N2H4, is an important industrial reagent. It is synthesized by the Raschig process.

2NaOH(aq) + Cl2(g) + 2NH3(aq) --> N2H4(l) + 2NaCl(aq) + 2H2O(aq)

If you combine 100. g each of NaOH, Cl2, and NH3 and the reaction is complete, which reactant(s) will be left over?

1. NaOH 2. Cl2 3. NH3

a. 1 only
b. 2 only
c. 3 only
d. 1 and 2 only
e. 2 and 3 only

I need to know the answer to these problems. Please, please help me!!!! THANKS SO MUCH!!!!!!!!


1. The reaction below was known to proceed at 85.3% yield of SO2.

P4S5(s) + 5O2(g)--> P4O10(s) + 5SO2(g)

(Molar mass P4S5 = 284.2 g/mol)

How many grams of P4S5 must be burned in excess oxygen to produce 50.0 grams of SO2

2.

I'm a junior. I've taken biology, chemistry, and now I'm taking chem 2. Most juniors are taking physics right now, but i thought chem 2 would be better. Next year i think i'm going to take two science classes, Anatomy and Physiolgy, and Cell Biology. Should I take physic's instead of taking one of these classes.
