Recall that equivalents are the mole ratio between reagents. Consider the synthesis of Dulcin using 0.700 g of phenetidine and 0,500 grams of potassium cyanate. If we say that there are 1.00 equivalents of phenetidine, how many equivalents of potassium cyanate are you using in the reaction? Be sure to report your answer to 3 significant figures

1. Saccharin is an artificial sweetener that was discovered in 1879 when a chemist spilled some of his product on his sandwich, and when he ate his sandwich discovered it was particularly sweet. It is synthesized according to the following reaction and the product is isolated after addition of HCI. -NH₂ + NaOH + KMnO4 NH OS=0 a) What safety rule did our chemist violate when discovering saccharin? (1 pt) b) Redraw the structure of the carbon-containing starting material, explicitly...

Explanation:
A mole ratio is the ratio between the amounts in moles of any
two compounds involved in a chemical reaction. The mole ratio can
be determined by examining the coefficients in front of formulas in
a balanced chemical equation.
Step 1: write the balanced chemical
equation.
Sb2S3(s) + 3Fe(s)→2Sb(s) +3FeS(s)
Step 2: calculate the moles of
Sb2S3 , Fe
Moles of Fe = mass given / molar mass = ( 25 g
/...
