In the United States, 30-day yield is a standardized yield calculation for bond funds. The formula for calculating 30-day yield is specified by the U.S. Securities and Exchange Commission (SEC). [1] The formula translates the bond fund's current portfolio income into a standardized yield for reporting and comparison purposes. A bond fund's 30 ...
Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...
If one has $1000 invested for 30 days at a 7-day SEC yield of 5%, then: (0.05 × $1000 ) / 365 ~= $0.137 per day. Multiply by 30 days to yield $4.11 in interest. If one has $1000 invested for 1 year at a 7-day SEC yield of 2%, then: (0.02 × $1000 ) / 365 ~= $0.05479 per day. Multiply by 365 days to yield $20.00 in interest.
Treating a month as 30 days and a year as 360 days was devised for its ease of calculation by hand compared with manually calculating the actual days between two dates. Also, because 360 is highly factorable, payment frequencies of semi-annual and quarterly and monthly will be 180, 90, and 30 days of a 360-day year, meaning the payment amount ...
The theoretical molar yield is 2.0 mol (the molar amount of the limiting compound, acetic acid). The molar yield of the product is calculated from its weight (132 g ÷ 88 g/mol = 1.5 mol). The % yield is calculated from the actual molar yield and the theoretical molar yield (1.5 mol ÷ 2.0 mol × 100% = 75%). [citation needed]

Collision theory is a principle of chemistry used to predict the rates of chemical reactions. It states that when suitable particles of the reactant hit each other with the correct orientation, only a certain amount of collisions result in a perceptible or notable change; these successful changes are called successful collisions.
where A and B are reactants C is a product a, b, and c are stoichiometric coefficients,. the reaction rate is often found to have the form: = [] [] Here is the reaction rate constant that depends on temperature, and [A] and [B] are the molar concentrations of substances A and B in moles per unit volume of solution, assuming the reaction is taking place throughout the volume of the ...
