The given chemical equation represents the reaction between sodium (Na) and trifluoromethylphosphinic acid (CF3PH(O)OH) to form sodium trifluoromethylphosphinate (CF3PH(O)ONa). In this reaction, sodium, a highly reactive metal, donates an electron to form a positively charged ion (Na+), while trifluoromethylphosphinic acid, an acidic compound, donates a proton (H+) to form a negatively charged ion (CF3PH(O)O-). The overall reaction can be summarized as follows: Sodium (Na) reacts with trifluoromethylphosphinic acid (CF3PH(O)OH) to produce sodium trifluoromethylphosphinate (CF3PH(O)ONa) and hydrogen gas (H2). This reaction is an example of an acid-base reaction, where sodium acts as a base and trifluoromethylphosphinic acid acts as an acid.
The CAS Registry Mumber 381-91-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,8 and 1 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 381-91: (5*3)+(4*8)+(3*1)+(2*9)+(1*1)=69 69 % 10 = 9 So 381-91-9 is a valid CAS Registry Number.
