Answer:
The embryo, endosperm, and seed coat are the three major parts of a seed. An embryo is the young multicellular organism formed before it emerges from the seed. A seed is an embryonic plant, which stores food and is enclosed in a protective outer covering, which give rise to a new plant.
Explanation:
Dehydrohalogenation reactions occurs as elimination reactions through the following mechanism:
Step 1: A strong base(usually KOH) removes a slightly acidic hydrogen proton from the alkyl halide.
Step 2: The electrons from the broken hydrogen‐carbon bond are attracted toward the slightly positive carbon (carbocation) atom attached to the chlorine atom. As these electrons approach the second carbon, the halogen atom breaks free.
However, elimination will be slower in the exit of Hydrogen atom at the C2 and C3 because of the steric hindrance by the methyl group.
Elimination of the hydrogen from the methyl group is easier.
Thus, the major product will A
Answer:
Exothermic
General Formulas and Concepts:
<u>Chemistry</u>
<u>Thermodynamics</u>
- Exothermic - releases heat as a product
- Endothermic - absorbs heat as a reactant
Explanation:
We are given that the reaction takes place between C₂H₄ (g) and H₂O (g) to form CH₃CH₂OH (g) and is <em>releasing heat</em>.
This means that heat would be product as it is being released during the reaction.
Therefore, we have an exothermic reaction.
Answer:
159.7 g Fe2o3/1 mol Fe2o3
Atomic radius increases as you move left across the periodic table, therefore, potassium will have the largest atomic radius
