Answer:
Plutonium is the second transuranium element of the actinide series.
Answer:
The equilibrium concentration of NO is 0.001335 M
Explanation:
Step 1: Data given
The equilibrium constant Kc is 0.0025 at 2127 °C
An equilibrium mixture contains 0.023M N2 and 0.031 M O2,
Step 2: The balanced equation
N2(g) + O2(g) ↔ 2NO(g)
Step 3: Concentration at the equilibrium
[N2] = 0.023 M
[O2] = 0.031 M
Kc = 0.0025 = [NO]² / [N2][O2]
Kc = 0.0025 = [NO]² / (0.023)(0.031)
[NO] = 0.001335 M
The equilibrium concentration of NO is 0.001335 M
Bohr's Model agree with Thompson's model because Bohr concluded that packets of energy are absorbed or emitted by the atoms when an electron changes shell. Thompson's conclusion states that atoms have small, negatively charged particles (referring to Electrons) as part of their internal structure.
oxygen, sulfur and selenium as they are all in the same group of the periodic table - they are all chalcogens
Mass of Silver chloride-AgCl = 28.314 g
<h3>Further explanation</h3>
Given
1.01 L of a 0.196 M solution of Silver nitrate
Required
Mass of Silver chloride
Solution
Reaction
AgNO₃ + NaCl ⇒ AgCl + NaNO₃
mol of AgNO₃ :
mol = M x V
mol = 0.196 x 1.01
mol = 0.198
From equation, mol ratio of AgNO₃ : AgCl = 1 : 1, so mol AgCl = 0.198
mass AgCl (MW=143 g/mol) :
mass = mol x MW
mass = 0.198 x 143
mass = 28.314 g
