How reactive are they? (Reactivity Level)?

Just in general\n\nAlkali Earth Metals- Pretty reactive they are found in many compounds\n\nBoron group- Low reactivity\n\nCarbon group- More reactive then boron group but still pretty low\n\nNitrogen group- More reactive then Carbon group\n\nOxygen group- Very reactive oxygen has an unually high affinty for electrons relative to where it is on the periodic table\n\nHalogen group- Even more reactive than oxygen th&#92;ey have very hi\naffinity for electrons\n\nNoble gases- Basically inert, they have a full outer orbital of electrons and will only react in rare cases such as with flourine

they react with 2- ions or 2 x 1+ ions to form salts\nThey are reactive in water\nWhat more do you need?

Inductive reactance can be calculated using this formula: XL = 2πfL\n\nGood Luck

How about the reaction slugs have to salt?

First let's find how many moles of each one we have\n\nmole= M*V, so for \nFeCl3 =0.234*25*10^-3= 5.85*10^-3\nNaOH =0.453*42.5*10^-3 =19.25*10^-3\n\nFeCl3 + 3NaOH -> Fe(OH)3 + 3NaCl\n\nso\n\n1mole FeCl3 reacts with 3mole NaOH\n5.85*10^-3 mole react with x\n\nThus x =3*5.85*10^-3=17.55*10^-3 mole NaOH but we have 19.25*10^-3 mole NaOH, therefore NaOH is in excess\nTherefore the amount of Fe(OH)3 will be calculated according to the limiting reageant FeCl3.\n\nso from the reaction\n\n1 mole FeCl3 gives 1 mole Fe(OH)3\nor better yet, since the molecular weight of Fe(OH)3 is 106.85 \n1 mole FeCl3 gives 106.85 g Fe(OH)3\n5.85*10^-3 mole give x g\nx= 106.85*5.85*10^-3= 0.625 g\n\nWe calculated that 17.55*10^-3 mole NaOH reacted.\nSo we have remaining (19.25-17.55) *10^-3= 1.7*10^-3 mole NaOH\n\nThese are in a total volume of 25.0+42.5=67.5 ml= 67.5*10^-3L.\n\nSo the concentration of the excess NaOH is\nC=mole/V= 1.7*10^-3/67.5*10^-3= 0.025 M

They act as a catalyst which sppeds up the reaction

An element is reactive because it is unstable.By reacting with other substances it tries to become stable.\nin case of metals or as u say positively charged elements,say,Li,Na,K...the atomic size is increasing on going down.As the size increases the the nuclear pull for the valence shell decreases,thereby making it easier to lose electrons.Thus,K easily loses electrons as compared to Na or Li and is therefore more reactive.\nin case of negatively charged atoms or non metals,the atomic size is again increasing for eg in case of F,Cl,Br..\nbut the case is opposite here.\nthe atom has to gain one electron in order to become stable.\nthe smaller the atom the more is the nuclear pull for the incoming electron and more readily it is accepted.\nthus in this case,reactivity decreases down the group.

A reaction tends to be spontaneous if  it causes an increase in the entropy of the system, and/or a decrease in the enthalpy of the system \n\nBoth reactions are endothermic (increase in enthalpy) becuase of positive delta H values.\nBoth have an increase in entropy (positive delta S value for the first one, production of a gas for the second)\n\nSo I'd say statements ll and lll are true.

flammable , orderless, colorless . have low frozen point ,reactive

!!!!!!!!!!!!!!!! \nI think rather u wanted to ask how can u predict the formula of a chemical reaction!!\nFirstly, we have to determine the moles of reactant taking part.(It can be done easily, think A reacts with B, just mix 1 mole of A with the same amount of B.)\nThen determine what are the different products and their amounts.\nAll u have to do is some calculations..................\nRemember its not as easy as it sounds.

Yes . but when the reaction begins, these temperatures will equilibrate\n\nIt is sometimes not possible to react if one compound is solid and the other is liquid

alkenes r more reactive as they can undergo addition reactions too due to the presence of double bonds while alkanes can undergo only substitution reactions.alkynes r evn more reactive as they hv triple bonds.\nwat is a soptier flame????\n\nbromine test.alkene will decolourize the bromine while alkane will not.

1. AgCl(s) + NaNO3\n\n2. AgOH(s) + NaNO3\n\n3. They would not react as both are nitrates already
