Sodium is more ELECTROPOSITIVE THAN ALUMINUMExplanation:As sodium is an ALKALI metal in FIRST group WHEREAS ALUMINIUM is in third group and electropositivity DECREASES across the period.

it CHANGES the colour to RED pls MARK me as brainlist

Because they are non metals that EXIST as covalent molecules which are HELD together by weak Van-der WALL forces and THUS the bonds break EASILY with less kinetic energy i.e less heat compared to electrovalent compounds.

e KNOW that an Olfactory indicator is a substance whose smell varies depending on WHETHER it is MIXED with an acidic or basic solution. Olfactory indicators can be USED in the laboratory to test whether a solution is a base or an acid, a process called olfactory titration.¯\(°_o)/¯

The ANSWER is "AMBIENT ATMOSPHERE".

chemical BOND is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond MAY result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bond MAKE me brainlist please give me some THANKS

tion:CALCULATE `DeltaU` if `2kJ` HEAT is RELEASED and `10kJ` work is done on the SYSTEM.

The large electronegativity differences between HARD acids and hard BASES give rise to strong IONIC interactions. ... The polar covalent compounds readily form either more ionic or more covalent compounds if they are allowed to REACT

tion:Electrolysis is CHEAPER COMPARED to other methods and generally the results are permanent. The SOLUTION used which is made up of electrolysis keeps the metal free from CORROSION or rusting. ... Chlorine can be prepared by electrolysis of a solution of common salt. Hydrogen is ALSO prepared by electrolysis of water.Hope it's helpful for you

Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity MAKES it possible for plastics to be moulded, extruded or pressed into SOLID objects of various shapes. ... Plastics TYPICALLY are MADE through human industrial systems.

Chloroform is PREPARED by the chlorination of methane. ... Chloroform is FORMED by the REACTION of CHLORINE with organic substances present in WATER and thus can occur in drinking water that has been chlorinated

+ Cl2-->2N2 + 2NH4Clb) 2NaHCO3 → Na2CO3 + H2O+CO2c) 2NaOH + H2S04 → Na2SO4+2H20d) CACO3 +2 HCI → CaCl2 + H2O+CO2

it WOULD TURN to nuetralExplanation:

बेकिंग सोड्याला कार्यरत होण्यासाठी त्यात ACIDIC म्हणजेच आंबट पदार्थ मिसळले जातात . जसे कि व्हिनेगर, ताक, लिंबाचा रस, दही यासारखे पदार्थ तुम्ही वापरत असाल तर बेकिंग सोडा त्याला रिअ‍ॅक्ट करून त्यामधून कार्बनडाय ऑक्साईड बाहेर पडतो.Explanation:I hope it's helpful for you THANKS me MARK me as BRANILIST vote me as exelent

I don't UNDERSTAND your QUESTION

by the formula.Explanation:FIND MOLES DIVIDE by CONSTANT

tion:Mass of A ATOM = 1 amu. Mass of B atom = 2 amu. Edge length = 1 NM.

- D block elements tend to be hard and they have relatively high densities when COMPARED to elements of the same period. From the above STATEMENTS we can say that the incorrect option is that d block elements have complete d orbitals. THEREFORE, the CORRECT answer is option (D).

Brase is the ALLOY of ZN and CU

When we mix ACETIC acid with ammonia it will TURN into sodium acetate. When we HEAT that sodium acetate it turns into ACETAMIDE and water.Explanation:mark me brainliest

Thereby we can calculate the mass of 1 molecule of SO3 as =32+(16×3)=80 amu. The mass of 20 MOLECULES of SO3 is =80×20=1600. That is 50 molecules of oxygen weigh as much as 20 molecules of SO3. It is important to REMEMBER that the molecular mass of oxygen is 32amu and the atomic mass of oxygen is 16 amu.

In PROBABILITY THEORY, a balance EQUATION is an equation that describes the probability flux associated with a Markov chain in and out of states or set of states.

Haan JI,mera NAAM SURBHI hAapka intro?EXPLANATION:#queen♥️

Gram atomic mass of WATER (H2O) = (1×2+16) gm = (2+16) gm = 18 gm ∴ Number of molecules in 18 gm of water = 1 MOL ∴ Number of MOLECULE in 1 gm of water = 1/18 mol ∴ Number of molecule in 3.6 gm of water = (1/18 X 3.6)mol = 0.2 molExplanation:

the answer is simpleExplanation:it's because because when heat is too hot we tend to stay in cooler PLACES since we are humans our blood cells and our blood almost in every part inside of our body is made HOTAND some places the blood is cold.When we sweat alot the blood inside our body becomes very cold thus making your body cold too. so as we may KNOW we humans want to stay in hot places when it is cold outside and when it is hot outside we like to stay cool inside and so does our blood which makes the sense of TOUCH for our body. for ex if your blood is cold tour body becomes cold. if your blood becomes hot our body becomes hot. so our blood/body. So we feel COMFORTABLE from a fan when we are perspiring. I hope this helps you

tahydrate (x = 5) is the most COMMON form. Older names for this compound include blue vitriol, bluestone, vitriol of COPPER, and ROMAN vitriol. The pentahydrate (CuSO4·5H2O), the most commonly encountered salt, is bright blue.Anhydrous copper sulfate is a light grey POWDER.#нσρє íт нєℓρѕ♡~#мαяк αѕ вяαíηℓíѕт☘️
