Krypton...it is based off of its location on the periodic table
Answer:
The larger bottom pan will be cooler than the smaller bottom pan, because the energy that transferred to it will have spread out over more molecules.
Explanation:
Answer: 8 moles of hydrogen reacts with 1 mole of sulfur.
Explanation: We are given a balanced chemical equation:
By Stoichiometry, it is said that
8 moles of Hydrogen gas reacts with 1 mole of sulfur to produce 8 moles of hydrogen sulfide.
Mole ratio of reactants = Hydrogen : Sulfur = 8 : 1
Answer:
Ea = 210.5kJ/mole
Explanation:
When the reaction:
O3 + NO → O2 + NO2
Occurs, requires 10.7kJ/mole and releases -199.8kJ/mole.
For the forward reaction:
O2 + NO2 → O3 + NO
The Ea is the sum of Ea of the forward reaction and - ΔH, that is:
Ea = Ea - (-ΔH)
Ea = 10.7kJ/mol - (-199.8kJ/mol)
Ea = 210.5kJ/mole
<h3><u>Answer</u>;</h3>
pH = 4.38
<h3><u>Explanation;</u></h3>
Consider that ;
[H3O+] = 10-pH mol/L
Therefore; the pH is the -log of the [hydronium ion].
pH = - log [H3O+]
Thus;
pH = - log (4.2 × 10^–5)
= 4.38
