                                           [Co(NH₃)₅Br]²⁺

Ligands and charges on them,

                             5 × NH₃  =  5 × 0  =  0

                             1 × Br⁻¹  =  1 × -1  =  -1

Charge on sphere  =  +2

So, putting values in equation,

                                       Co + (0)₅ - 1  =  +2

                                       Co + 0 - 1  =  +2

                                       Co - 1  =  +2

                                       Co  =  +2 + 1

                                       Co  =  +3

Result:
           Oxidation state of Co in [Co(NH₃)₅Br]²⁺ is +3.

solniwko [45]

Answer:

CH4 +O2 => CO2 + 2 H2O

None were in excess

Explanation:

Equation for the reaction is,

CH4 + O2 =>CO2 +2 H2O

No of moles of CH4 = (20 /1000)/24 =0.02 /24 = 0.00083

No of moles of O2 =20 /24000 = 0.0083

CH4 : O2 = 1:1

THEREFORE

None of the gases were in excess.

15 points + brainliest pls help :(
Komok [63]

Answer:

27 g

Explanation:

M(C6H12O6) = 6*12 + 12*1 + 6*16 = 180 g/mol

100 mL = 0.1 L solution

1.5 M = 1.5 mol/L

1.5 mol/L * 0.1 L = 0.15 mol  C6H12O6

0.15 mol * 180 g/1 mol = 27 g C6H12O6
