No, because not everything consists of matter. Some things consist of dark matter other are ether and what we tend to see trillions of particles making up matter.
Hope I helped :-)
Answer:
rate = [NO]²[O2]
Explanation:
The rate law for the reaction:
2 NO(g) + O2(g) → 2 NO2(g)
Is expressed in terms of reactants as follows:
rate = [NO]ⁿ[O2]ˣ
<em>Where n and x are the coefficients of the rate law.</em>
<em />
If [NO] is doubled, the rate increased 4 times. That is only possible if:
rate = [NO]²[O2]ˣ
Now, as [NO] is doubled and increased the rate 4 times, and [NO] + [O2] when doubled increased the rate 8 times, doubled [O2] implies increased the rate 2 times. That is only possible is:
<h3>rate = [NO]²[O2]</h3>
Answer: 61 grams
Explanation:
To calculate the number of moles, we use the equation:
The chemical equation for the combustion of octane in oxygen follows the equation:
By stoichiometry of the reaction;
25 moles of oxygen react with 2 moles of octane
4.69 moles of oxygen react with=
moles of octane
Thus, oxygen is the limiting reagent as it limits the formation of product and octane is the excess reagent.
25 moles of oxygen produce 18 moles of water
4.69 moles of oxygen produce=
moles of water.
Mass of water produced=
The maximum mass of water that could be produced by the chemical reaction is 61 grams.
a...if you had the fully extended periodic table, these elements would be between La and Hf in period 6 and Ac and Rf in period 7
Protons is the number of the element on the periodic table. Electrons are the same number of protons and i'm sorry I do not know neutrons, I hope I helped!
