Answer:
26. Hemoglobin is a tetramer that consists of four polypeptide chains. Each monomer contains a heme group in which an iron ion is bound to oxygen.
Explanation:
The answer is: when the aim is to show electron distributions in shells
An orbital notation is more appropriate if you want to show how the electrons of an atom are distributed in each subshell. This is because there are some atoms that have special electronic configurations that aren't obvious in just written configurations.
Answer:
16 °C
Explanation:
Step 1: Given data
- Provided heat (Q): 811.68 J
- Mass of the metal (m): 95 g
- Specific heat capacity of the metal (c): 0.534 J/g.°C
Step 2: Calculate the temperature change (ΔT) experienced by the metal
We will use the following expression.
Q = c × m × ΔT
ΔT = Q/c × m
ΔT = 811.68 J/(0.534 J/g.°C) × 95 g = 16 °C
Answer:
If you change the number of neutrons somehow, nothing will happen because it carry's no charge at all.
Explanation:
Answer:
1.5 moles
Explanation:
The equation of the reaction is given as:
2 MnO2 + 4 KOH + O2 --> 2KMnO 4 + 2KOH + H2
From the equation,
2 moles of MnO2 produces 2 moles of KMnO4
x moles of MnO2 would produce 1.5 moles of KMnO4
2 = 2
x = 1.5
Solving for x;
x = 1.5 * 2 / 2
x = 1.5 moles
