ANSWER:

Seminormal NACL solution means 0.5 M solution and density of solution is 1.16 g /cc.

Mass of one litre of solution = 1000 x 1.16 = 1160 g

Mass of solute in one litre of solution = 58.5 x 0.5 = 29.25 g

Mass of solvent = 1160 -29.25 =1130.75 g = 1.13075 kg

Molality = 0.5 MOLE/ mass of solvent in Kg

= 0.5 / 1.13075 = 0.442 m

PS: In REALITY , density of 0.5 m solution will be lower than 1.13 g / cc

Answer:

A COVALENT bond, also CALLED a molecular bond, is a chemical bond that INVOLVES the sharing of ELECTRON pairs between atoms. ... For many molecules, the sharing of electrons allows each atom to attain the equivalent of a full OUTER shell, corresponding to a stable electronic configuration

Answer:

Explanation:

MOLES of  Na2SO4 = 7.2/142

= 0.05

0.05 mole contain = 2 * 0.05*6.022*10^23

= 6.022 * 10^22 OD Na

and 0.05*6.022*10^23

= 3.011*10^22 mole of SO2

ANSWER:

NITROGEN

Explanation:

Nitrogen WOULD be the ELEMENT

Explanation:

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another.[1] Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between ATOMS, with no change to the nuclei (no change to the elements PRESENT), and can often be described by a chemical equation. Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur.

The substance (or substances) initially involved in a chemical reaction are called reactants or reagents. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have PROPERTIES different from the reactants. Reactions often consist of a sequence of individual sub-steps, the so-called ELEMENTARY reactions, and the INFORMATION on the precise course of action is part of the reaction mechanism. Chemical reactions are described with chemical equations, which symbolically present the starting materials, end products, and sometimes intermediate products and reaction conditions.

Answer:

Rays are positively charged: Anode rays are deflected towards the negative plate of an ELECTRIC FIELD. They are deflected by ELECTRICAL and magnetic FIELDS just as the cathode rays but in opposite directions showing that they are oppositely charged, i.e., they carry positive charge.✌️

Answer:

The mass number is DEFINED as the TOTAL number of protons and neutrons in an atom. CONSIDER Table below which shows DATA from the first six elements of the periodic table. Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus.

You need to enable JavaScript to run this app. The elements which change their valency or show more than one electrovalency are said to possess variable electrovalency. This is DUE to following two reasons. Now due to increase of effective nuclear CHARGE FE3+ does not lose more electron.

Given:-:

Neutron NUMBER= 7

ATOMIC mass= 12

To FIND :-

The representation

•Solution:-

We know

Atomic number= proton number

Atomic mass = Proton number+ Neutron number

Neutron= - Proton number + Atomic mass

Proton number = Atomic mass - Neutron number = 12 -7 = 5

and we know that the ELEMENT is DETERMINED by the proton count .

As the proton number is 5

So this element is written as B-11.

Hello MATE,

Carbonation is the process of dissolving CARBON dioxide in LIQUID. The process usually involves carbon dioxide under high PRESSURE. When the pressure is reduced, the carbon dioxide is released from the solution as small bubbles, which causes the solution to "fizz". This effect is seen in carbonated soft drinks.

Hope this HELPS you

Explanation:

roasting-the action of cooking something in an OVEN or over an open fire.

calcination-The IUPAC defines calcination as "heating to high temperatures in air or oxygen". However, calcination is also used to MEAN a thermal treatment process in the ABSENCE or LIMITED supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition.

refining-remove impurities or unwanted elements from (a substance), typically as part of an industrial process.

Answer:

The QUALITY in a SOUND of being DEEP,FULL,and reverberating. ......XD

Explanation:

ph=6.2

so, Ka=10^-6.2 .......... {^}denotes = power

Now, DISSOCIATION =√Ka/concentration

=√10^-6.2/0.05

approximately =0.004

so, %=0.004*100

=0.4

This is CORRECT answer.

Answer:

hey mate

Explanation:

An atom is smallest particle in an element that has the properties of the element. It is not possible to breakdown the atom further retaining the properties of the element. Atoms are not visible to the naked eye and are the basic building blocks. For example the atoms of element gold cannot be broken down further and each atom has the properties of gold.

Molecules are formed by the combination of TWO or more atoms. Unlike atoms, molecules can be subdivided to individual atoms. The atoms are BONDED together in a molecule. Molecules also are not visible to the naked eye, while can be seen through highly magnifying microscopes and other scientific devices. Water is COMPRISED of numerous water molecules.
