Answer:

Two methods which help us to conserve water are:

Sprinkler irrigation system: this irrigation has an arrangement of vertical pipes with rotating nozzles on the top. It is more useful in the uneven and sandy land where sufficient water is not available.

Drip irrigation system: this irrigation system has an arrangement of pipes or tubes with very small holes in them to water plants drop by drop just at the base of the root. It is very efficient as water is not wasted at all.

When H 2SO 4 is neutralized by NaOH in aqueous solution, the net ionic equation is ________. SO42- (aq) 2Na (aq) Na2SO4 (aq) SO4

puteri [66]

Answer:

2H+ + SO4^2- +2Na+ + 2OH- ------------> 2Na+ + SO4^2- + 2H2O

Explanation:

In writing ionic reaction equations, we omit spectator ions, that is, ions that do not participate actively. Both the reactants and products are broken up into their constituent ions and a balanced equation involving ions only is written. Ionic equation balance usually require good knowledge of the reaction and nature of the reactants The dissolved compounds only are written as ions.

Give a possible explanation for the relative amounts of the isometric methyl nitrobenzoates formed in the nitration reaction. Co

vovikov84 [41]

Answer:

The electrophilic aromatic substitution reaction nitration is used to nitrate methyl benzoate and acetanilide with a nitronium ion. Crystallization was used to purify the product. The melting point was used to determine its purity and the regiochemistry of the products.

Explanation:

Methyl m-Nitrobenzoate is formed in this

reaction rather that ortho/para isomers

because of the ester group of your starting

product of methylbenzoate. The functional

group of ester is a electron withdrawing group

causing nitrobenzene (N02) to become in the

meta position. Thus N02 is a deactivating

group causing itself to be a meta director.

Basically you must look at the substituents

that are attached to your starting benzene ring

in order to figure out whether your reaction

with be ortho/para directors or meta

directors. If the substituents are electron

withdrawing groups then you will be left with

meta as your product but if your substituents

are electron donating groups then your

product will be ortho/para.

Draw the most stable conformation of 3-isopropyl-1,1dimethylcyclohexane Please show me which one is the isopropyl and the dimeth

Andrei [34K]

The most stable conformation of 3-isopropyl-1,1dimethylcyclohexane equatorial ethyl group (more stable). The stability of ethylcyclohexane's equatorial conformer exceeds that of its axial conformer by 7.4 kJ/mol.

According to the previous section, the chair conformation with the equatorial methyl group is more stable because it reduces steric repulsion, and as a result, the equilibrium favors the more stable conformer. Strongly favoring the equatorial shape is methylcyclohexane. The methyl group is in close proximity to the axial hydrogens in the axial conformation, which has an energetically unfavorable effect known as a 1,3-diaxial interaction. The methyl group prefers the equatorial shape as a result. The conformation of ethylcyclohexane in which the ethyl group is in the equatorial position is the most stable.
