The ions are held together by strong electrostatic FORCES. Ions with UNLIKE CHARGES attract each other. The positive Na⁺ ions attract the NEGATIVE Cl⁻ionshope this will HELP you follow me and Mark me Brainlist

your answer mate...Gases exert pressure in all directions. ... The gas particles have very weak attractive force between them, and move randomly ultimately exert pressure in all DIRECTION. Their molecules are BOUNCING all AROUND the CONTAINER because they are so small, then gravity has very little effect on them.Hope this helps u to understand... Plzz follow me.. Mark me as a BRAINLIST answer.. Plzz thanks it...

plz mark it as brainlistExplanation:Factors which Affect CorrosionThe main factors which affect corrosion are1.More the reactivity of metal, the more will be the possibility of the metal getting corroded.2.The impurities help in setting up voltaic CELLS, which increase the SPEED of corrosion3. Presence of electrolytes in water also increases the rate of CORROSION4. Presence of in natural water increase rusting of iron.5.When the iron surface is coated with layers of metals more active than iron, then the rate of corrosion is retarded.6. A rise in temperature (with in a reasonable limit) increases the rate of corrosion.

a optionExplanation:the ANSWER is very SIMPLE 5 sides are there so it will START with PENTA and it is Pentylecyclopentane

I answered ur question pls mark me as BRAINLIEST.....................and follow me........................Explanation:15.7mm of Hgn = 4, l = 3, m = +1, s =+1/2  ANSWER d.....................                                                   Second IONISATION energy of potassium is greater than that of Ca. In case of potassium ion (i.e. K+) the electron removal from the stable inert gas CONFIGURATION (1s22s22p53s23p5) requires much higher energy. Velocity v=10m/s The lobes of the dxy orbital are oriented in between the axes at an angle of 450 . So the maximum probability of finding an electron is 450 in between x and y axesHalf of this =0.5×20N=10N atoms.option a and b

water vapour, COCONUT oil, COMMON saltExplanation:solids have highest force of attraction between PARTICLES present and GASES have WEAKEST force of attraction between particles liquids lie in between

because CHEMICAL doesn't MATCH broExplanation:GOOGLE krle

Hope it will HELP you .......... PLEASE mark me as BRAINLIEST...........EXPLANATION:

in AlCl³ ,Al is positively chargedsince Al+ Cl-³because only 3election is present in 3s² 3p¹ orbital,so it give its electron to chlorine and form Al+. since chlorine has only 1 electron left to complete its octate so 3 chlorine atom combine with 1 aluminium atom to form Al+ Cl-³ or Alcl³so due to POSITIVE charge and vacant 3 orbital it exhibit greater power TOWARD NEGATIVE colloid while on other side K⁴[Fe(CN⁶)] has no such REQUIREMENTS so it is wrong answer and correct answer is AlCl³

At standard Temperature and PRESSURE (STP) the molar volume (Vm) is the volume OCCUPIED by one MOLE of a chemical element or a chemical COMPOUND. It can be calculated by DIVIDING the molar mass (M) by mass density (ρ

A mixture of sand and iron fillings can be separated with the HELP of a magnet. The iron fillings will GET ATTRACTED to the magnet, LEAVING behind the sand. This is an EXAMPLE of MAGNETIC SEPARATION.I hope this will help you

Adding a common cation or common anion to a solution of a SPARINGLY soluble salt shift the solublity EQUILIBRIUM in the direction predicted by Le Chatelier's principle. The solublity of the salt is almost always decreased by the presence of a common ion.Hope it's helpful...........PLZ mark as brainlist...............Explanation:

Light has massExplanation:Light is COMPOSED of photons, so we could ask if the photon has mass. The ANSWER is then definitely "no": the photon is a massless particle. According to theory it has energy and momentum but no mass, and this is confirmed by EXPERIMENT to within STRICT limits. Even before it was known that light is composed of photons, it was known that light carries momentum and will exert pressure on a surface. This is not evidence that it has mass since momentum can exist without mass.But reflection doesn't.....

1.As we go from innermost SHELL outwards, this number denotes the number of subshell in the shell. Electrons in outer shells have higher average energy and travel farther from the nucleus than those in inner shells. Hence, M shell contains s,p and d subshells.2.The 4d sub-energy level is at a lower energy than the 5p sub-energy levelFor 4d, n=4 and l=2. Hence, (n+l)=4+2=6For 5p, n=5 and l=1. Hence, (n+l)=5+1=6As the value of (n+l) for 4d orbital is same as that of 5p orbital, 4d orbital is FILLED before 5p orbital as 4d orbital has lower value of n than 5 p orbital.Note: If two orbitals have same value of (n+l), then the orbital with lower value of n will be filled . 3.Similarly, L shell is the second shell and it can hold up to 2(2)2 = 8 electrons.4.NITROGEN is the seventh element with a total of 7 electrons. In writing the electron configuration for nitrogen the FIRST two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for N goes in the 2s orbital. ... Therefore the N electron configuration will be 1s22s22p3.hope this Will help you

If HYDROGEN GAS is passed over heated copper OXIDE (CuO), the black coating on the surface turns brown as the reverse REACTION takes place and copper is obtained. ... The hydrogen is gaining oxygen and is being oxidised.In other words, one reactant gets oxidised while the other gets reduced.Explanation:I I hope this is helpful for you you please FOLLOW me friend if you follow me I will follow you back

Benefits INCLUDE: Fuel CELLS have a higher efficiency than diesel or gas engines. Most fuel cells operate silently, compared to internal combustion engines. ... If the hydrogen comes from the electrolysis of water driven by renewable energy, then USING fuel cells ELIMINATES greenhouse gases over the whole cycle.

100 g of the compound CONTAINS 69.9 g iron and 30.1 g oxygen. The atomic masses of iron and oxygen are 55.85 amu and 16.00 amu. The number of moles of Fe present in 100 g of compound are   55.85 69.9 ​   =1.25   The number of moles of O present in 100 g of compound are   16.00 30.1 ​   =1.88   The MOLE ratio of Fe to O is   1.88 1.25 ​   =0.67:1 or 2:3 Hence, the empirical formula is Fe  2 ​   O  3 ​   mark as BRAINIEST :)

ng you need to be careful of with LIZARDS is that they carry harmful BACTERIA like SALMONELLA. This is transmitted via their feces and urine and can cause serious ILLNESS. The symptoms are SEVERE diarrhea, stomach cramps, fever and vomiting. For those with weakened immune systems, this illness can be fatal.

the main THING is the AREA of the ROOF larger the area greater the storage or seepage of WATER underground!!!

Organic compounds are those in which both carbon and hydrogen are presentExplanationCO2 is not organic COMPOUND because hydrogen is not PRESENT A compound in which both carbon and hydrogen are present is CALLED a organic compoundHope it HELPS. ☺️

For an ALDOHEXOSE such as GLUCOSE, the C-1 aldehyde in the open-chain form of glucose reacts with the C-5 hydroxyl group to form an INTRAMOLECULAR hemiacetal. The resulting cyclic hemiacetal, a six-membered ring, is called PYRANOSE because of its SIMILARITY to pyran
