Answer:
π = MRT
= × RT
= ×RT
MM = mxRxT / πxL
MM = 8.00g ×0.0821×298/ 2.86×0.200L
= 342.2 g/mol
Explanation:
the molecular weight of the sugar can be determined by using the osmotic pressure formula.the formula has to be worked on in order to get the molar mass of the sugar.the name of the sugar is called sucrose.
The reaction CFCl3 + UV Light -> CFCl2 + Cl does not need another reactant as with CFCl3 because the reaction itself is reactive to light. Note that there are reactions that are sensitive to light to form products and when this type of reaction are not exposed to light, no reaction occurs.
M(N)=21.2 g
M(N)=14.007 g/mol
n(N)=m(N)/M(N)
n(N)=21.2g/(14.007g/mol)=1.51 mol
Noble gases belong to group 18 of the periodic table. These elements are inert because they have their valence orbital shells as ‘full’ hence do not participate in reactions since they cannot share electrons. These elements have a pattern in their electron configuration. Their outer most orbital shells has 8 electrons (with the exception of 2 for helium).
Answer:
At pH0 the more thermodynamically stable species is lower and the most strongly oxidizing species is higher. At pH14 the more thermodynamically stable species is higher and the most strongly oxidizing species is lower . At pH0 convex curve will tend to disproportionate and pH14 concave curce will tend to disproportionate. Under acidic conditions mixing Mn3+(aq) and MnO42- (aq) will result in the formation of redox oxidation-reduction reaction.
