Nuclear fission differs from nuclear fission because nuclear fusion reactions

Nuclear reactions have two main types: fission reactions and fusion reactions. When two light nuclei are joined to create a heavier and more stable nucleus, this process is called the fusion reaction. In the fission reaction, the heavy nucleus split into two nuclei with a smaller mass number. In other words, fission is splitting of atoms although not all atoms undergo fission, only few went through normal circumstances (that is a fact).

List and explain the four most important factors that control the relative reactivity of a carbonyl-containing functional group

ioda

Resonance, leaving group, carbonyl carbon delta+, and steric effect is the most crucial variables that affect the relative reactivity of a functional group containing a carbonyl in an addition or substitution process.

Discussion:

1. Carbonyl Carbon Delta+: The carbonyl group becomes more electrophilic and accelerates nucleophilic assault when the carbonyl carbon delta+ is bigger.

2. Resonance: When the carbonyl is transformed into the tetrahedral adduct, it may be lost. Loss of resonance increases the energy of the transition state for this nucleophilic assault because resonance has the function of stabilizing. Therefore, a carbonyl functional group's resistance to nucleophilic attack increases as resonance in the group increases in importance.

3. Leaving group: Tetrahedral adduct fragmentation is encouraged by a better LG.

4. Steric effects: The nucleophilic attack on carbonyl carbon is delayed when sterically impeded.

Question 21 of 25

Nady [450]

Answer:

B. Acid + base = salt + water

Explanation:

In accordance to the proposal of a scientist called Svante Arrhenius, an acid is a substance that increases the H+ concentration of a solution by dissociating into it while the base increases the OH- concentration of a solution by dissociating into it. Furthermore, Arrhenius stated that this two ions combine in an aqueous solution to give water.

Hence, Arrhenius acid-base reaction is the combination of an acid and base to produce salt and water as products. That is; Acid + base = salt + water.

A 0.1 m solution of which salt is the most basic? (a) nano3 (b) naclo4 (c) nahso4 (d) nahco

lbvjy [14]

Answer is: d) NaHCO₃ - sodium hydrogen carbonate or sodium bicarbonate.
It is because other salt are made in reaction between strong base and strong acid and sodium hydrogen carbonate is made from strong base (sodium hydroxide) and weak acid (carbonic acid).
Sodium bicarbonate is an aqueous solution is used for cases of acidosis.
