Magnetic moment of V(Z = 23),Cr(Z = 24),and MN(Z= 25) are x,y. Solution : V=(Z=23)⇒3d34s2(N=3) (n is the number of UNPAIRED electrons) (x). The more the number of unpaired electrons, the higher is the magnetic moment.

Explanation:

Molar conductivity increases with a decrease in CONCENTRATION. This happens because the total volume, V, of the solution containing one mole of electrolyte also increases. UPON DILUTION, the concentration DECREASES.

Explanation:

Precipitation is the creation of a solid from a solution. When the reaction occurs in a liquid solution, the solid formed is called the 'precipitate'. The chemical that CAUSES the solid to form is called the 'precipitant'. ... The precipitate-free liquid remaining above the solid is called the 'supernate' or 'supernatant'.

Effervescence is foaming or fizzing that RESULTS from a gas being evolved from a solid or liquid. The term comes from the LATIN verb fervere, which means "to boil." The word "fermentation" has the same source.

The most COMMON gas released in effervescence is carbon dioxide, however nitrogen gas may be DISSOLVED in liquids to produce smaller bubbles.

Answer:

The region between 400 cm-1 and 1500 cm-1 in an IR spectrum is KNOWN as the fingerprint region. It usually contains a LARGE number of peaks, making it difficult to IDENTIFY individual peaks. HOWEVER, the fingerprint region of a given compound is unique and, therefore, can be used to DISTINGUISH between compounds.

Answer:

It's the reaction between Phenol and Aldehyde.

Explanation:

Here, Phenol is REACTING qith Aldehyde to give o- methane-diol and p- methane-diol since Phenol is a ortho-para DIRECTING group.

Here, the p- methane-diol will be the chief product because, in o- methane-diol, there is steric hindrance DUE to which it BECOMES a minor product.

ANSWER:

OXYGEN SUPPORTS BURNING.

ANSWER:

CUO +  H₂ ⇒ CU + H₂O

Explanation:

CuO is GETTING REDUCED and H₂ is getting oxidised.

Answer:Ca(OH)2 +2 NH4Cl -> CaCl2 + 2 NH3 + 2H2O.

Thus 1 mole of Ca(OH)2 requires 2 MOLES of NH4Cl.

number of moles of in 100 g of each of reactants is

for Ca(OH)2 100 g / 74g mol^-1 = 1.35 moles

for NH4Cl. 100 g÷ 53.5 g mol^-1= 1.87 moles

In this case, NH4Cl is a LIMITING reagent

1.87 moles of it will REACT with 1.35/2= 0.675 moles of Ca(OH)2 producing 1.35 moles of NH3 i.e. 34 g × 1.35 =45.9 g of it.

Since 1 mole of any gas OCCUPIES 22.4 L

1.35 × 22.4 L corresponds to 30.24 L .

ALKYNES can be reduced to trans-alkenes with the use of sodium dissolved in an ammonia solvent. An Na radical donates an electron to one of the P BONDS in a carbon-carbon TRIPLE BOND. This forms an ANION, which can be protonated by a hydrogen in an ammonia solvent.

Answer:

he state of Science (s) and Technology in Agriculture. 1. ABSTRACT Sugar industry plays a great role in the socio-economy of Ethiopia since it produces sugar for household and industrial consumptions, provides great job opportunity for the nationals, serves as source of energy and co-products are used for miscellaneous purposes. COMMERCIAL sugarcane cultivation in Ethiopia started in 1954 at Wonji on 5000 ha. At present sugarcane is cultivated on 37,000 ha and the four sugar mills produce about 300,000 ton sugar per annum. However, this PRODUCTION could not satisfy the domestic consumption, and thus the deficit is being offset by importing sugar from abroad. To bridge the gap between supply and demand as well as to exploit the international market, besides expanding the existing ones, Ethiopia is in the course of establishing new sugar factories with large tract of sugarcane PLANTATION with the aim of attaining production of 2.25 million tons sugar and 181 million liters of ethanol at the end of the year 2014/15. There is an evident gap between the potential yield and the yield level achieved so far though productivity of the plantations seems high when compared with many other countries. This may be attributed to the combined impact of limited management creativity and use of limited improved technological developed in situ or abroad. Thus, the cane agriculture in Ethiopia still needs improved technologies that can alleviate the existing production challenges namely lack of high yielding MODERN cane varieties, prevalence of diseases and pests, reduced land productivity, RISE of soil and water management related problems, etc.

In chemistry, a salt is a chemical compound consisting of an ionic assembly of cations and ANIONS. Salts are composed of related numbers of cations and anions so that the product is electrically neutral

Explanation:

A salt CONSISTS of the positive ION (cation) of a base and the negative ion (anion) of an acid. The reaction between an acid and a base is called a neutralization reaction. The TERM salt is also used to refer specifically to common table salt, or sodium CHLORIDE.

Answer:

CHEMICAL EFFECT KI vajah SEE. ....

Explanation:

A SOLUBLE salt can be prepared from a reaction between an acid and a metal, a base or a carbonate.

Reaction 1: Acid + alkali → salt + water.

Reaction 2: Acid + metal → salt + hydrogen.

Reaction 3: Acid + base → salt + water.

Reaction 4: Acid + metal carbonate → salt + water + carbon dioxide.
