Solution :Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.Dry ice sublimes easily. Iodine will sublimes easily .Ammonium chloride also sublimes easily but salt NaCl do not.
Explanation:First, we ensure that the equation is balanced. Then, we convert the given grams to moles of reactant. We use that to determine the moles of the product from the...
1. b] Pressure is the force per unit area applied in a direction perpendicular to the surface of an object. a] The density of a material is defined as its...
n(Cl2) = 8.3 molesSolution:Sodium + chlorine = sodium chloride.The equation of a chemical reaction:2Na + Cl2 = 2NaClAccording to the chemical equation: n(Na)/2 = n(Cl2) = n(NaCl)/2.Therefore,n(NaCl) = 2*n(Cl2) =...
Solution:Sodium + chlorine → sodium chloride The balanced chemical equation:2Na + Cl2 → 2NaClAccording to the equation above: n(Na) = n(NaCl)Moles of Na = Mass of Na / Molar mass of NaThe molar...
Solution: If sodium chloride is 39.34% sodium, then chlorine in sodium chloride: 100 – 39.34 = 60.66% If in 60.66% - 2 g in 100% - x, Then x=100x2/60.66=3.297 g...
. m (HCl) =30.8 g .m (NH4Cl)=? The reaction is NH4Cl= NH3 + HCl Let's find the amount of substance (HCl)= m(HCl)/ Mr(HCl) Mr (HCl)= Ar(H)+ Ar(Cl)=1+35.5= 36.5 . n=30.8/36.5=0.84...
Answer: Combination which makes less soluble product shift towards left side of the equation.Pb(NO3)2 + 2NaCl = PbCl2 + 2NaNO3PbCl2 + Na2CrO4 = PbCrO4 + 2NaClPbCrO4 + Na2S = PbS...
