Hydrogen gas is not evolved when a metal reacts with nitric acid. It is because HNO3 is a strong oxidising agent. It oxidises the H2 produced to water and itself gets reduced to any of the nitrogen oxides (N2O, NO, NO2). But MAGNESIUM (Mg) and MANGANESE (Mn) react with very DILUTE HNO3 to evolve H2 gas

halpy is defined by H = E + PV for a change in the states of system ΔH = Δ (E + pV) = ΔE + Δ (pV) = ΔE + pΔV + VΔp ....(i) 1st LAW of thermodynamics states that ΔE = Q + W = q - pΔV ....(ii) From equations (i) and (ii) ΔH = q - pΔV + pΔV + VΔp = q + VΔp When the pressure is constant, Δp = 0, and thus VΔp = 0, therefore ΔH = q (at constant pressure) or, ΔH = qP

hemistry, an electrophile is a chemical SPECIES that forms bonds with nucleophiles by accepting an electron pair.[1] Because electrophiles ACCEPT electrons, they are Lewis acids.[2] Most electrophiles are positively charged, have an atom that carries a partial positive CHARGE, or have an atom that does not have an octet of electrons.Electrophiles mainly interact with nucleophiles through addition and substitution reactions. Frequently seen electrophiles in organic syntheses include cations such as H+ and NO+, polarized neutral molecules such as HCl, alkyl halides, acyl halides, and carbonyl compounds, polarizable neutral molecules such as Cl2 and Br2, oxidizing agents such as organic peracids, chemical species that do not satisfy the octet rule such as CARBENES and radicals, and some Lewis acids such as BH3 and DIBAL.(ii)Nucleophile is a word used to refer to substances that tend to donate electron pairs to electrophiles in order to form chemical bonds with them. Any ion or molecule having an electron pair which is free or a pi bond containing two electrons have the ABILITY to behave like nucleophiles.

mical equation for dissociation of weak acid HA is represented as follows : Calculating the concentration of acid using percent dissociation and initial concentration of acid as follows :Thus, the concentration of hydronium ION will be equal to the concentration of dissociated acid that is 0.000004 M.Now, the pH of acid will be CALCULATED as follows :Now, the POH of the acid will be calculated as follows :Therefore, the pOH of weak acid is 8.6

plz make me brainlistExplanation:The equilibrium reaction is C2H4+H2⇔C2H6.The units of the equilibrium constant are (MOLES/lit)Δn.Here, Δn is the difference in the total NUMBER of moles of PRODUCTS and reactants.Δn=1−(1+1)=−1.Hence the UNIT of the equilibrium constant becomes (moles/lit)−1=Ltr.Mole−1.

tion:COVALENT COMPOUND, two major TYPES of chemical bonds can be observed between atoms. ... The main difference between hyperconjugation and resonance is that hyperconjugation INVOLVES the interaction between a sigma bond and a p orbital or a pi bond whereas resonance involves the

1. Portland cementPortland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the EARLY 19th century by Joseph Aspdin, and usually originates from limestone.2. Cement is manufactured through a closely controlled chemical combination of calcium, SILICON, aluminum, iron and other ingredients. Common MATERIALS used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ORE.

A MOLECULE is defined as TWO or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound COMPOSED of more than one element, as with WATER (H2O).Explanation:hope it will help you !. be HAPPY !. :)

In chemistry, neutralization or NEUTRALISATION is a chemical reaction in which ACID and a base react quantitatively with each other. In a reaction in WATER, neutralization results in there being no excess of HYDROGEN or hydroxide ions present in the solution.

Molar mass of calcium hydroxide = 74 g/moleMolar mass of magnesium sulfate = 120 g/moleMolar mass of calcium carbonate = 100 g/moleGiven hardness of magnesium sulfate = 60 ppmThe BALANCED chemical reaction will be,MgSO_4+Ca(OH)_2\rightarrow CaSO_4+Mg(OH)_2MgSO 4 +Ca(OH) 2 →CaSO 4 +Mg(OH) 2 First we have to calculate the hardness of magnesium sulfate in TERMS of calcium carbonate.\text{Hardness of }MgSO_4=\frac{\text{Given hardness of }MgSO_4}{\text{Molar mass of }MgSO_4}\times \text{Molar mass of }CaCO_3Hardness of MgSO 4 = Molar mass of MgSO 4 Given hardness of MgSO 4 ×Molar mass of CaCO 3 Now put all the given values in this expression, we get the hardness of magnesium sulfate in terms of calcium carbonate.\text{Hardness of }MgSO_4=\frac{60ppm}{120g/mole}\times 100g/mole=50ppmHardness of MgSO 4 = 120g/mole60ppm ×100g/mole=50ppmNow we have to calculate the amount of LIME required.\text{Amount of lime}=\frac{74}{100}\times 50mg/L\times 5000L=185000mg=185gAmount of lime= 10074 ×50mg/L×5000L=185000mg=185gTherefore, the amount of lime required is, 185 GRAMS
