The important thing to note is the reason why electron react is due to the instability of the electrons. All elements wants to aim the electron configuration of the noble gases. This is the most stable form in which each of the orbitals are sufficiently filled. When it comes to bonding, the order of reactivity is: alkynes > alkenes > alkanes. Alkynes are compounds with triple bonds, alkenes with double bonds and alkanes with single bonds. The single bonds are called saturated hydrocarbons. This is because they have reached stability, so it is quite difficult to react this with reducing or oxidizing agents. Alkynes and alkenes are unsaturated hydrocarbons. They readily react with reducing and oxidizing agents so as to become saturated, as well. The underlying principle for this is that single bonds contain sigma bonds which is the head-on overlapping of electrons. These is the strongest type of covalent bond. Double and triple bonds contain pi bonds which is the side overlapping of electrons orbitals. Hence, these electrons would be easily separated making it more reactive especially during protonation.
Answer:
The given statement is true.
Enzymes which are present in the digestive tract such as salivary amylase, pepsin, trypsin, et cetera mainly catalyze the hydrolysis reaction.
The hydrolysis reaction is the reaction by which large molecules are broken down into smaller molecules with the help of water.
Most of the complex molecules or nutrients such as starch, protein et cetera are broken down into their respective smaller units with the help of hydrolysis reaction.
For example, lactase catalyzes the hydrolysis of lactose into glucose and galactose.
Answer:
PCl₃
Explanation:
To determine the empirical formula of a compound, we need to follow a series of steps.
Step 1: Divide each percent composition by the atomic mass of the element
P: 22.6/30.97 = 0.729
Cl: 77.4/35.45 = 2.18
Step 2: Divide all the numbers by the smallest one, i.e. 0.729
P: 0.729/0.729 = 1
Cl: 2.18/0.729 ≈ 3
The empirical formula of the compound is PCl₃.
Answer:
B.sugar solution
Explanation:
A sugar solution is not a compound.
Rather, the solution is a mixture and an impure substance.
- A compound is composed of two or more kinds of atoms or elements joined in a definite grouping .
- The properties of the compound is distinct from those of the individual atoms that makes them.
- Sugar solution is sugar and water
- It is made up of two compounds not chemically combined.
The name of the compound NiSO4 • 5H2O is <u>nickel (II) sulfate pentahydrate.</u> Since there is <span> a transition metal cation with multiple oxidation states, you have to include the Roman numeral in the brackets.
Ni is nickel, so the first part is obvious. Since there are four equivalent oxygen atoms in a tetrahedral arrangement, it is also a sulfate. Penta refers to number 5, and hydrate because it consists water.</span>
