Question 1. Considering the reaction of the decomposition of N2O5 to form the products NO2 and O2, calculate the average reactio

n rate if at 0.00s the concentration of N2O5 was 1.00 M and at 4.00s it decreases to 0.987 M?
2 N2O5 4 NO2 + O2
4.97 × 10-1 mol/(L × s)
7.27 × 10-2 mol/(L × s)
6.50 × 10-3 mol/(L × s)
3.25 × 10-3 mol/(L × s)

<span>
 </span><span> average reaction rate </span><span>= change in concentration / change in time
by putting values we have

 = (1.00M - 0.987M) / (4.00s - 0.00s)
 = 3.25x10^-3 mol/Lsec
this is our conclusion
hope this helps</span>

What is one substance that is 100x more acidic than baking soda
daser333 [38]

Answer:

An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water, the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide ions in the solution. This kind of solution is acidic.

If two gases with pressures of 2 atm and 3 atm are mixed at a constant temperature, what will the total pressure be?
slamgirl [31]
If two gases with pressures of 2 atm and 3 atm are mixed at constant temperature, the total pressure will be the sum of the two pressures. Therefore the answer is D. 2 atm + 3 atm or 5 atm will be the total pressure of the gas mixture.

Summarize the five points of Dalton’s atomic theory, and explain at least one change that occurred to the atomic theory because
Umnica [9.8K]
The postulates of Dalton's theory were:
1) Elements are made of extremely small particles called atoms
2) <span>Atoms of a given element are identical in size, mass, and other properties
</span>3) <span>Atoms cannot be subdivided, created, or destroyed</span>
4) Atoms combine in whole number ratio to form compounds
5) Chemical reactions are the rearrangement of atoms
The third postulate has been disproved by modern science, in which the atom has been split and been subdivided into smaller parts such as the neutron, proton and electron, which are further subdivided into quarks, gluons, and kaons.
The second postulate was also disproved upon the discovery of isotopes.

If you reacted 93.7 grams of iron with excess copper sulfate solution, what mass of copper would you expect to make? you may nee
Mariana [72]

Answer is although the question should have 3 significant figures.

<h3>What is significant figures?</h3>
  • Chemical equation

Fe + CuSO4 --> Cu + FeSO4

It is already balanced

  • Molar ratios

1 mol Fe : 1 mol CuSO4 : 1 mol Cu : 1 mol FeSO4

  • atomic masses of Fe and Cu

Fe: 55.8 g/mol

Cu: 63.5 g/mol

  • number of moles of Fe

number of moles = mass in grams / atomic mass = 93.7 g / 55.8 g/mol = 1.679 mol

  • number of moles of Cu:

1 mol Fe / 1 mol Cu => 1.679 mol Fe / 1.679 mole Cu

  • mass of Cu in 1.679 moles Cu

mass = atomic mass * number of atoms = 63.5 g/mol * 1.679 moles = 106.6 g = 107 rounded to 3 significant figures.
