math
for a strict triangular form, does it has to be in I matrice or just the main diagonal entries are all 1]\

math
in a skew symmetric, how do we explain that its diagonal entries has to be all 0 without giving examples to support it

engineering
what is the device used called for eye laser surgery and do you know which company use it

chemistry
CoSO4 + KI + KIO3 + H2O  Co(OH)2 + K2SO4 + I2 2KI yield I2 + 2e 2KIO2 10e yield I2 are there 10 electrons being transferred or just 5 only

chemistry
HCl (aq) + Cu (s) + HNO3 (aq) yield CuCl2 (aq) + NO (g) + H2O (l) do i say that HNO3 is oxidizing agent or just N+5 is the oxidizing agent

chemistry
can you what is G and G knot in terms of spontaneity and chemical equilibrium. I know that G is spontaneous when is negative but what does G knot tell you

chemistry
because it gives 1893.5g, it threw me off. I wasnt sure if it was there to trick me

chemistry
The electrochemical cell described by the cell notation has a standard cell potential of -0.35 V. Calculate the Wmax (kJ) the cell has done if 1893.5 g of MnO42-(aq) (Molar Mass - 118.94 g/mol) forms. Round your answer to 3 significant figures. Pt(s) | Hg22+(aq), Hg2+(aq)||MnO...
