Answer : The length of a one-dimensional box for an electron is 
Explanation :
The energy level of quantum particle in a one-dimensional box is given as:
where,
= 479 kJ/mol = 479000 J/mol
n = energy level = 1
h = Planck's constant = 
m = mass of electron = 
L = length of a one-dimensional box = ?
Now put all the given values in the above formula, we get:
conversion used : 
Therefore, the length of a one-dimensional box for an electron is
Answer: Given equal masses, water will heat up less than wood if the same heat is added.
Answer: Hello!
first i believe we need a balanced equation to start...
i got 2H2 + 1O2 = 2H2O
This tells us that we need 2 moles of H2 for every 1 mole of O2 Since we only have 1 mole of H2 compared to the 5 moles of O2 hydrogen is the limiting reagent. For illustration, divide the balanced equation by 2 in order to get 1 mole of H2 If we start with 1.0 moles of H2 we'll produce 1.0 mole of H2O

Explanation:
The fact that some of the solid was transferred would decrease the mass of the limiting reactant.
<h3>What is the limiting reactant?</h3>
We know that in a chemical reaction, there are at least two substances that are combined in order to give the product of the reaction. We also know that the product that we obtain must be in accordance to the stoichiometry of the reaction.
It is common to see that one of the reactants would be present in a very large amount while the other reactant would be present only in quite a small amount. The reactant that is present in a small amount is said to be the limiting reactant while the one that is present in the large amount is said to be the reactant that is in excess.
Having said this, we know that the mass of the limiting reactant can be obtained from the mass of the solid that is obtained after the reaction.
If we do not take out all of the solid from the centrifuge, the mass would not be accurately weighed and the mass of the limiting reactant would not be accurately determined.

Answer:
When a large, fissile atomic nucleus such as uranium-235 or plutonium-239 absorbs a neutron, it may undergo nuclear fission. The nucleus splits into two or more lighter nuclei, releasing kinetic energy, gamma radiation, and free neutrons.
