Show a sample of each calculation performed. This calculation should include the math formula and the example with substituted values. All data should have proper significant figures and units. we placed 50 ml of 2.00M HCL into the inner cup. stired the solution untill the temperatew stabilized. placed 50 ml of 2.02 M NaOH into 100 m beake. pour the NaOH solution as completely as possible into the calorimeter with the first solution. we also did the same proces using 50 ml 2.00 M HNO3

You have .900 mol of H atoms in the ground state. How much energy is required to transition all of the atoms from the ground state to n=4

Calculate E

For the following reaction, 18.2 grams of iron are allowed to react with with 9.56 grams of oxygen gas.

I know this is multiple questions but it is in the same question on my HW and i'm so confused

What is the maximum amount of iron(II) oxide that can be formed? And What is the FORMULA for the limiting reagent? And What amount of the excess reagent remains after the reaction is complete?

1. The activation energy for the gas phase decomposition of dinitrogen pentoxide is 103 kJ.

N₂O_5--------- NO₂ + 1/2 O₂
The rate constant at 314 K is 2.76×10^-4 /s. The rate constant will be 1.49×10^-3 /s at -----------k

2. The activation energy for the gas phase decomposition of dinitrogen pentoxide is 103 kJ.

N₂O_5-----------2 NO₂ + 1/2 O₂
The rate constant at 305 K is 8.40×10^-5 /s. The rate constant will be ------- /s at 345 K.

What is a thermochemical equation? How is this different than a chemical equation? please appreciate typewriting when responding to this question  

How does these chemical equation balance, step by step? Why do they balance this way?

I already know how they balnace I just don't understand how they balance.

why does the O(2*) balance to 25? 2 C(8*)H(18*) + 25 0(2) yields 16 CO(2*) + 18 H(2*)O

These ones have me stumped as well

1 C(3)H(8) + 5 O(2) = 3 CO(2) + 4 H(2)O

Why does this equation balance this way?

1 Pb(OH)(2) + 2 HCl = 2 H(2)O + 1 PbCl(2)

Pb(OH)(2) + HCl + H(2)O + PbCl(2)

As I look at this equation, I am immediatly stumped because of the (OH). It kind of looks like it affects the whole equation, but I don't know why or know.

Please explain to me, in depth, why and how these equations balance this way

In a chemiluminescence lab do any factors completely stop light generation? If so, which ones?
