A) rh(o2cch3)4(h2o)2 has the same structure as moz(o2cch3)4with two axially bound water molecules. the rh-rh bond distance is 2.386 å (rh metal, 2.698). given the orbital arrangement for metal metal-metal bonding has been shown to be [0.(nt t), 8 (tt* 1"), 8", 6*] (i) draw molecular orbital energy level diagram for rh2. (ii) what is the bond order for rh-rh bonding?

answer: they produce more slow than unicellular organisms.

the answer is barium and copper bromide

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
