Give reasons for the followinga) sulphuric acid gives an acid salt but hydrochloric acid does notb) Dil.HCl is stronger than highly concentrated acetic acid

Answer»

Explanation:

a.)Sulphuric ACID is a strong acid and it gets completely ionized in aqueous solution. - Sulphuric acid on REACTION with a base gives both acidic salts and NORMAL salts.

while HCl being a monobasic acid is left with no HYDROGEN ions.

b.)In an acetic acid solution, there is a large number of undissociated CH3COOH molecules, and just a few H+ and CH3COO- ions. Hence, dilute HCl acid is stronger than highly concentrated acetic acid.

At 1323°C the equilibrium constant for the reaction :Br2(g) ------> 2Br(g); Kc=10^(-3)A 0.2L vessel containing an equilibrium mixture of gases has 0.24g Br2(g) in it. What is the mass of Br(g)in the vessel?

Answer»

MOLES Br2 = 0.245 g/ 159.808 g/mol=0.00153

[Br2]= 0.00153 / 0.190 L=0.00807 M

1.04 x 10^-3 = [BR]^2/ [Br2] = [Br]^2 / 0.00807

[Br]= 8.93 x 10^-6 M

moles Br = 8.93 x 10^-6 x 0.190=1.59 x 10^-6

mass Br = 1.59 x 10^-6 x 79.904 g/mol=0.000127 g

A solution has 50 gram of salt in 320g of water. Calculate the mass percent of the salt in the solution.With detailed steps...Please answer this question very soon, Don't post any other things,otherwise I must report it.​

Answer»

\sf{\huge{\underline{\orange{Given :-}}}}

  • A solution has 50 gram of salt in 320g of WATER.

\sf{\huge{\underline{To\:Find :-}}}

  • The mass percent of the salt in the solution.

\sf{\huge{\underline{\green{Answer :-}}}}

☀ The percent mass of component in a solution is KNOWN as the mass percentage of the solution .

Mass % of a component =

\frac{Mass\:of\:the\:component\:in\:the\:Solution }{Total\:Mass\:of\:Solution} × 100

We have,

Salt as a solute = 50 gram

Water as a solvent = 320 gram

The salt water solution = ( 50 + 320 )

= 370 grams

Mass % of a component = \dfrac{50}{370} × 100

➝ 0.135136 × 100

➝ 0.136 × 100

➝ \dfrac{136}{1000} × 100

➝ \dfrac{136}{10}

➝ 13.6 %

I) Define atomic mass unit.ii) What is the numerical value of mole. iii) Name the elements present in oxide ionpaper question of 9th class annual exam cbse JNV AKOLA​

Answer»

{ \huge{ \mathfrak{ \underline{ \underline{ \pink{Aꪀsᴡꫀr}}}}}}

Hᴇʀᴇ ɪs ᴜʀ Aɴsᴡᴇʀ

ǫᴜᴇsᴛɪᴏɴ :-

☆ Define atomic mass unit.

☆ What is the numerical value of mole.

☆ Name the elements present in oxide ion

----------------------------------------------

ᴀɴsᴡᴇʀ :-

1 . ☆ A unit of mass used to express atomic and molecular WEIGHTS, equal to ONE twelfth of the mass of an atom of carbon-12.

☆ An atomic mass unit is defined as a mass equal to one twelfth the mass of an atom of carbon-12. The mass of any ISOTOPE of any element is expressed in relation to the carbon-12 standard. For example, one atom of helium-4 has a mass of 4.0026 amu.

----------------------------------------------

2 .☆ One mole contains exactly 6.022 140 76 x 1023 elementary entities. This number is the fixed numerical value of the AVOGADRO constant, NA, when expressed in the unit mol–1 and is called the Avogadro number.

----------------------------------------------

3 .☆ An oxide (/ˈɒksaɪd/) is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O2– (molecular) ion. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2.

X Delilne types of chemical equationwith the help of suitable ex Balanced chemical equation for Combination reaction​

Answer»

Explanation:

During a chemical reaction, the substances that react are known as REACTANTS whereas the substances that are formed during a chemical reaction are known as PRODUCTS. Six common types of chemical reactions are discussed below.

Types of Chemical Reactions Explanation General Reaction

Combination reaction Two or more compounds combine to form one compound. A + B → AB

Decomposition reaction The opposite of a combination reaction – a complex molecule breaks down to MAKE simpler ones. AB → A + B

Precipitation reaction Two SOLUTIONS of soluble salts are mixed resulting in an insoluble solid (precipitate) forming. A + Soluble SALT B → Precipitate + soluble salt C

Neutralization reaction An acid and a base react with each other. Generally, the product of this reaction is a salt and water. Acid + Base → Salt + Water

Combustion reaction Oxygen combines with a compound to form carbon dioxide and water. These reactions are exothermic, meaning they give off heat. A + O2 → H2O +

Answer»

Answer:

When Alkali metals are HEATED in excess air BASIC nature of OXIDES are formed.

The reducing nature is determined by the tendency of losing electron. Since this tendency is LOWER in alkaline earth metal than alkali metal, the FORMER are weaker reducing agent.

When sodium metal is heated in a free supply of air, sodium peroxide (Na2O2) along with small amount of sodium oxide is formed. When sodium peroxide is dissolved in water, hydrogen peroxide is produced
