<span>The electron configuration of lead is [Xe] 6s2, 4f14, 5d10, 6p2 according to the Aufbau principle.</span>
Answer:
About 60 grams
Explanation:
The balanced equation of the reaction is given as;
2H2(g) + O2(g) → 2H2O(l)
From the equation;
2 mol of H2 reacts with 1 mol of O2
3 mol of H2 would require 3/2 mol of O2 (considering the 2:1 ratio)
The limiting reactant is H2 as it would be used up before H2. It determines the amount of product that would be formed.
2 mol of H2 produces 2 mol of H2O
3 mol of H2 would produce 3 mol of H2O (Considering the 1 : 1 ratio)
Converting moles to mass;
Mass = Molar mass * Number of moles
Mass = 18 * 3 = 54 g
The correct option is; About 60 grams
Answer:
[H+] = 1.66 x 
Explanation:
To find the [H+] concentration of a solution, we can use the formula:
![[H+] = 10^{-pH}](https://tex.z-dn.net/?f=%5BH%2B%5D%20%3D%2010%5E%7B-pH%7D)
Let's plug in the pH.
![[H+] = 10^{-3.78}](https://tex.z-dn.net/?f=%5BH%2B%5D%20%3D%2010%5E%7B-3.78%7D)
Evaluate the exponent.
[H+] = 1.66 x
Hope this helps!
<span>Aqueous solution is something where water is solvent. When the aqueous solution is saturated in both potassium chlorinate and carbon dioxide gas at 85C, the carbon dioxide bubbles out of the solution. The hydrophobic substances do not get dissolved in the water.</span>
Answer:
B
Explanation:
because polarity of the water molecules is due to the B. deflection of the hydrogen atoms by the lone pair of electrons.
