The heat converts into another ENERGY and it makes the SOLID MELT......and again if you ,KEEP it in the same SHAPE and heat it ,it will chnage after cooling .....
is this answer okay?
hope this will help you.

When we THROW any OBJECT it can be FALL on the earth because earth have a gravitational FORCE

The COMPOSITION will BECOME 23.2 LITRE .

Nuclieophility increses as we go down the group......so iodide ION is better NUCLEOPHILE than bromide ion because iodine is one ROW down.....the bromine in PERIODIC table.....

This is the question of limiting reactant
22.4 liter of H2 GIVES 22.4 liter of hcl


And 22.4 liter of CL2 gives 22.4 liter of hcl
1 liter gives 22.4 ÷22.4 liter of hcl
11.2 liter of hcl gives 22.4 ÷ 22.4 ×11.2 liter of hcl
= 11.2 liter of hcl


So cl2 is limiting reactant
11.2 liter of cl2 gives 11.2 liter of hcl
Moles = volume ÷ 22.4
Moles = 11.2 ÷22.4
Moles = 0.5 moles

And its MASS is mass = mole × MOLECULAR mass
Mass = 0.5 × 36.5
Mass in gram = 18.25

Electrolysis of water is the decomposition of water into Oxygen and hydrogen gas due to an electric current passed through the water. The REACTION has a STANDARD potential of −1.23 V, meaning it ideally requires a potential difference of 1.23 volts to split water.

This technique can be used to make hydrogen FUEL (hydrogen gas) and BREATHABLE oxygen; though currently most INDUSTRIAL methods make hydrogen fuel from natural gas instead.

As per the Moeller's diagram 3P ORBITAL is higher in ENERGY than a 3s orbital in a hydrogen atom I have ATTACHED the Moeller's diagram picture for your reference hope this helps :)

Heyaa,,,
You can prepare shop by ;
Fats and oils are HYDROLYZED (SPLIT) with a high-pressure steam to yield crude fatty acids and glycerine. The fatty acids are then purified by distillation and neutralized with an alkali to produce soap and WATER (neat soap). When the alkali is sodium hydroxide, a sodium soap is formed. Sodium SOAPS are "hard" soaps

Because in this a single reactant decomposes into TWO PRODUCTS..

Reactant -- BA Co3 (1 reactant )


Product -- BaO + Co2 ( 2 product )

Type -- thermal decomposition ( as heat is involved )

Miscible liquids

1. Liquids which mix together in all PROPORTIONS and form a single layer are called miscible liquids.

2. They are SEPARATED by the process of fractional distillation.

Immisible liquids

1. Liquids which do not mix with each other and form SEPARATE LAYERS are called immiscible liquids.

2. They are separated by USING separating funnel.

Hope you are satisfied

Hi,
Here is the answer to your query:-

The alkaline earth metals are six chemical elements in GROUP 2 of the periodic table. They are beryllium(Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar PROPERTIES: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.

Structurally, they have in COMMON an outer s- electron shell which is full; that is, this orbital contains its full complement of two electrons, which these elements readily lose to form cations with charge +2, and an oxidation state of +2.

All the discovered alkaline earth metals occur in nature.Experiments have been conducted to attempt the synthesis of element 120, the NEXT potential MEMBER of the group, but they have all met with failure.

PLS EXPLAIN your QUESTION.. its not COMPLETE

The rate of evaporation is affected by the FOLLOWING factors:

Temperature: The rate of evaporation INCREASES with an increase in temperature.Surface area: The rate of evaporation increases with an increase in surface area.Humidity: The amount of WATER vapour PRESENT in the air is called humidity. The rate of evaporation DECREASES with an increase in humidity.Wind speed: Evaporation increases with an increase in wind speed.

I THINK it is the RIGHT ANSWER.

This is DISPLACEMENT REACTION because more reactive ELEMENT DISPLACES less reactive element.
please mark as the brainliest ANSWER.

Methane has a molecular weight of 16 and 4 atoms PER molecule. Oxygen (O2O2) has a molecular weight of 32 and 2 atoms per molecule.

32G of SOMETHING with a molecular weight of 16 is 2 moles — since there’s 4 atoms, that’s 8 moles of atoms. Since oxygen MOLECULES have 2 atoms each, 8 moles of atoms yields 4 moles of O2O2 molecules. Since they are 32g per mole of O2O2, 4 moles x 32g / mole = 128g

Hope it's help you

Atomic mass of CA is 40 amu
That means for 40 amu its 1 atom

So 120 amu of Ca contains:
120/40=3 atoms

Thus the answer is 3 atoms.

This is the ANSWER of your QUESTION

In CHEMISTRY, sigma bonds (σ bonds) are the strongest type of covalent chemical bond.[1]They are FORMED by head-on overlapping between atomic orbitals. Sigma bonding is most SIMPLY defined for diatomic moleculesusing the language and tools of symmetry groups. In this formal approach, a σ-bond is symmetrical with respect to rotation about the bond axis. By this definition, common FORMS of sigma bonds are s+s, pz+pz, s+pz and dz2+dz2 (where z is defined as the axis of the bond or the internuclear axis).[2] Quantum theory also indicates that molecular orbitals(MO) of identical symmetry actually mix or hybridize. As a practical consequence of this mixing of diatomic molecules, the wavefunctions s+s and pz+pz molecular orbitals become blended. The extent of this mixing (or hybridization or blending) DEPENDS on the relative energies of the MO's of like symmetry.

HEY MATE HERE YOUR ANSWER IS...

In chemistry,ORBITAL hybridisation  (or hybridization ) is the concept of mixing atomic orbitals into NEW hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to FORM chemical bonds in VALENCE bond theory....

A type of energy fueled by the transfer of electrons from positive and NEGATIVE points within a conductor. Electricity is WIDELY used for providing power to buildings, electric devices, and even some automobiles. A number of individuals are responsible for the development of electricity, but the most notable one is BENJAMIN Franklin and his flying kite experiment. Franklin was ABLE to determine that lightning was a form of electrical discharge.
