Answer:
The chain of colored boxes represent the first eight amino acids in the beta chain of hemoglobin. The sixth position in the normal beta chain has glutamic acid, while sickle beta chain has valine. This is the sole difference between the two
Explanation:
Answer:
3 mol Cl₂/2 mol AlCl₃ (three over two)
Step-by-step explanation:
Start with the balanced equation"
2Al + 3Cl₂⟶ 2AlCl₃
The steps in the calculation are
mass of AlCl₃ ⟶ moles of AlCl₃⟶ moles of Cl₂ ⟶ mass of Cl₂
The critical step is the <em>conversion of moles</em>.
You multiply the moles of AlCl₃ by a <em>conversion factor</em> to get moles of Al:
Moles of AlCl₃ × conversion factor = moles of Al.
The conversion factor is <em>the molar ratio</em>, and it uses the coefficients of the formulas in the balanced equation.
It is either (2 mol AlCl₃/3 mol Cl₂) or (3 mol Cl₂/2 mol AlCl₃).
You choose the one that has the desired units of the answer in the numerator.
We choose the second option, because it has the correct units.
For example,

Notice how the units "mol AlCl₃" cancel and the correct units appear in the answer.
If we had used the other conversion factor, we would have gotten the wrong units.

Answer:
Exothermic reaction
Explanation:
Consider the reaction
A + B ⟶ C
If energy is released, the product C is at a lower potential energy level than the reactants A and B (see diagram).
Conversely, the reactants A and B are at a higher energy level than the product.
B is wrong. In an endothermic reaction, the reactants A and B are at a lower energy level than the product.
C and D are both wrong. Both types of reaction can be exo- or endothermic.
Answer:

2. 10 grams
3. ?
Explanation:
for number one, you simply. multiblu the 02 by 6 an that is 12, the same goes for number two. now for the third one i di not know. i am sorry and i hope this helps.
