Answer:

1. In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

2. Given below are some of the examples of the chemical reactions in our daily life:

Photosynthesis.

Combustion.

Aerobic cellular respiration.

Anaerobic respiration including the process fermentation.

Metathesis reactions, for example, vinegar and baking soda.

Oxidation which includes rusting.

Digestion.

3. A chemical formula is the combination of atomic symbols that designate a particular chemical compound, or a substance with two or more different elements. ... A chemical equation shows one or more chemical compounds (reactants) being converted into different chemical species called products.

Predict the order of acid strengths in the following series of cationic

stich3 [128]

Answer:

CH3CH=NH2+>CH3CH2NH3+

Explanation:

If we look at the both species under review, we will realize that they are both amines hence they possess the polar N-H bond.

Electrons are ordinarily attracted towards the nitrogen atom hence making both compounds acidic. It is worthy of note that certain features of a compound may make it more acidic than another of close structural proximity. 'More acidic' simply means that the proton is more easily lost.

CH3CH=NH2+ contains an sp2 hybridized carbon atom which is highly electronegative and further withdraws electron density from the N-H bond thereby leading to a greater acidity of CH3CH=NH2+ compared to CH3CH2NH3+

How will the reaction rate of the SN1 reaction change if the electrophile is switched from the tertiary electrophile to a second

lions [1.4K]

The reaction rate of the SN1 reaction change if the electrophile is switched from the tertiary electrophile to a secondary electrophile will decrease.

SN1 exhibits substitution, nucleophilicity, and monomolecular reaction, and is expressed by the expression rate = k [R-LG]. This means that the rate-determining step of the mechanism depends on the degradation of a single molecular species. Multi-step reactions include intermediates and multiple transition states (TS).

The SN1 reaction is a nucleophilic substitution reaction in which the nucleophile replaces the leaving group (similar to SN2). However, the SN1 reaction is a single molecule. The rate of this reaction depends on the concentration of only one reactant.

Explain the trend in reactivity of the halogens 6 marks

mojhsa [17]

Answer:

The reactivity of Group 7 elements decreases down the group. ... The electrons in the outer shell move further away from the nucleus as we go down the group and the attraction force between the electrons and the nucleus become weaker and weaker. This weaker attraction in the larger atoms makes it harder to gain electron.
