Over the time interval 300 to 400 seconds, the rate of reaction with respect to A is delta[A]/delta t =3.7 x 10^-5M/s. Over the same time interval what is the rate of reaction with respect to B, delta[B]/delta t? A) delta [b]/delta t = 3.7 x 10^-5 B) delta [b]/delta t = (1/4)(delta[a]/delta t) = (1/4)(3.7 x 10^-5M/s) =9.2 x 10^-6 M/s C)delta [b]/delta t = (1/2)(delta[a]/delta t) = (1/2)(3.7 x 10^-5M/s)=1.8X10^-5 D)delta [b]/delta t = -(1/2)(delta[a]/delta t) = -(1/2)(3.7 x 10^-5M/s)=-1.8X10^-5

If 155 of wet is collected over water at 24 and a barometric pressure of 738 , how many grams of have been consumed? (The vapor pressure of water is 22.38 .)
Calculate the percent of a strontium sample left after 100 years. The half-life of strontium-90 is 28.1 years.
What is a zymogen? Is it used over and over like other enzymes? And what is the physiological advantage
What volume of a 6.16E-2 M potassium hydroxide solution is required to neutralize 19.8 mL of a 0.107 M hydroiodic acid solution.
You performed these reactions in an acidic solution(diluting with 0.1MHNO3). This is because iron forms an insoluble hydroxide even when these solutions do not contain excess hydroxide ion (i.e. even in slightly acidic solutions)
