In the following examples I provided the fprintf input as a comma-separated list generated from a cell array, of course you can use a loop if you prefer.
Method 1: set the fprintf fieldwidth:
>> c = [x;num2cell(y);num2cell(z)];
>> fprintf('%-20s %8.2f %8.2f\n',c{:})
Butane 1859.59 371.92
Oxygen 4095.45 767.90
Nitrogen gas 13490.49 13490.49
Maleic anhydride 0.00 1757.00
Acetic acid 0.00 15.37
Acrylic acid 0.00 18.44
Carbon monoxide 0.00 412.25
Carbon dioxide 0.00 647.74
Water 0.00 1964.93
Total 19445.53 19446.04
Method 2: use char to fit all words:
>> c = num2cell(char(x),2).';
>> c(2,:) = num2cell(y);
>> c(3,:) = num2cell(z);
>> fprintf('%s %8.2f %8.2f\n',c{:})
Butane 1859.59 371.92
Oxygen 4095.45 767.90
Nitrogen gas 13490.49 13490.49
Maleic anhydride 0.00 1757.00
Acetic acid 0.00 15.37
Acrylic acid 0.00 18.44
Carbon monoxide 0.00 412.25
Carbon dioxide 0.00 647.74
Water 0.00 1964.93
Total 19445.53 19446.04
Method 3: no fprintf:
>> c = char(x);
>> c(:,end+1) = 32;
>> c = [c,num2str(y(:))];
>> c(:,end+1) = 32;
>> c = [c,num2str(z(:))];
>> c
c =
