1. it shows that particals of MATTER have RANDOM MOTION

the ANSWER to your QUESTIONS is 2

ermost orbit is called valence shell and the electron present in valence shell is called valence electrons. The OUTERMOST shell is 3RD shell so it is called valence shell of sodium and it CONTAINS 1 elctron so ,It's valence electron is 1. The elements comes under Group no 1,2and 3 are metals so sodium is metal .

The AVERAGE BOND ORDER in the sulfate ion is 1.5.MARK AS BRILLIANT ANSWER ✌✌

Since TOTAL no of SPECTRAL line =10(n1-n2)(n1-n2+1)/2=10n1-n2=4Now for max FREQUENCY n1-n2=4 Change in angular momentum=(n1-n2)h/2πSo y=4

n2+3h2~>is USED to PRODUCED AMMONIA when 450g of hydrogeExplanation: 1575g =1575 , 450 1575apon 450

er...... From your reaction equation, 3 moles of hydrogen gas produces 2 moles of AMMONIA if the reaction was 100% efficient. From the way you phrased your question, it's difficult to tell if you mean 450g of hydrogen (H), or 450 GRAMS of hydrogen gas (H2). I'll assume you mean hydrogen gas. FIRST you have to calculate the number of moles hydrogen gas you started with: Moles H2 = grams H2 / Molecular weight H2 Moles H2= 450 g H2 / 2.016 g per mole H2 Moles H2 =223.21 moles If the reaction was 100% efficient: Moles NH3 = 2/3 * moles H2 Moles NH3 = 2/3 * 223.21 Moles NH3 = 148.80 moles Now to calculate the grams NH3 expected from 100% efficiency: grams NH3 = moles NH3 at 100% efficiency * mol wt NH3 grams NH3 = 148.80 moles * 17.024 grams/mole grams NH3 = 2533.17 grams So to calculate the percent yield for the reaction: % yield = (actual yield/ theoretical yield) *100 % yield = (1575 grams/ 2533.17 grams) *100 % yield = 62.17% Now if you meant H instead of H2 for the original grams hydrogen in your question, you'll have to recalculate as appropriate....Hope this will HELP u..

compound because it is a CHEMICAL CHANGE and HENCE most properties of that compound will be different

:-➡Air has variable composition ➡It SHOWS the PROPERTIES of its CONSTITUENTS gases➡It ( liquid air ) can be separated into its constituents by fractional distillation ( physical process )➡Air ( liquid ) does not have a FIXED boiling POINT

please make me as brain list answer ..Explanation:The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no CHARGE). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged). ATOMS have different properties based on the arrangement and NUMBER of their basic PARTICLES.

it can be WINNOWING!!! or FILTERATION

Because it does not CONTAIN WATER to PRODUCES HYDROGEN IONS.

heya matecolloidal solutionExplanation:A colloid is ONE of the three primary types of mixtures, with the other two being a SOLUTION and suspension.

Explanation:PERCENT composition by elementElement SYMBOL Mass PercentMagnesium MG 72.244%NITROGEN N 27.756%

Explanation:The ammonia formed is dried using an unusual DRYING agent - calcium oxide, cao (quicklime). Ammonia is MADE commercially by the DIRECT combination of nitrogen and hydrogen using a catalyst - finely reduced (or divided) iron impregnated with aluminium oxide.Quick lime is basic in NATURE and hence does not react with ammonia, which is also basic in nature, WHEREAS all other drying agents are acidic in nature .

Physical change refers to a change in which the molecules are rearranged but their INTERNAL composition REMAINS same. Chemical Change is a process in which the substance TRANSFORMS into a new substance, having DIFFERENT chemical composition.
