Two chemical substances A and B react to form a chemical substance C. The reaction rate is proportional to the product of the quantities of A and B that have not reacted at an instant t. Initially there are 100 grams of A and 60 grams of B, in addition for each 2g of B 3g of A is required. It is observed that after 5 minutes 25g of C have been formed. How many grams of C will there be in 15 minutes? What is the limit amount of C after a long time? In how much time does half of that limit amount of C form? Plot the graph of the amount of C vs. time.

(1 point) Two chemicals A and B are combined to form a chemical C. The rate of the reaction is proportional to the product of the instantaneous amounts of A and B not converted to chemical C. Initially there are 75 grams of A and 24 grams of B, and for each gram of B, 1.7 grams of A is used. It has been observed that 24.75 grams of C is formed in 15 minutes. How much is formed in...

Two chemicals, A and B, react to form a chemical C such that every gram of C is made up of 2 parts A and 3 parts B. The rate of formation of C is directly proportional to the remaining amounts of A and B. If initially there are 60g of both A and B and after 3 minutes there's 25g of C how long until 50g of C are formed? Hint: for each part C, the amount of A...

5. Two chemicals, A and B, are combined, forming chemical C. The rate of the reaction is jointly proportional to the amounts of A and B not yet converted to C. Initially, there are 50 grams of A and 80 grams of B, and, during the reaction, for each two grams of A used up in the conversion, there are three grams of B used up. An experiments show that 100 grams of C are produced in the first ten...

Chemical A is transformed into chemical B with the rate at which B is formed varying directly with the amount of A that is present at any instant in time. If there is 20 kg of chemical A present at the beginning of the process, and it is known that it takes 2 kg of A to produce 1 kg of B, then find the amount of chemical B that is formed as a function of time, if after 30...

Nitrogen and fluorine react to form nitrogen fluoride according to the chemical equation: N2 (g) + 3F2(g) → 2NF3 (g) If a sample containing 19.3 g of N2 is reacted with 19.3 g of F2, how many grams of NF3 will be produced? Now we need to find the amount of NF3 that can be formed by the complete reactions of each of the reactants. If all of the N2 was used up in the reaction, how many moles of...

If a substance is radioactive, this means that the nucleus is unstable and will therefore decay by any number of processes (alpha decay, beta decay, etc.). The decay of radioactive elements follows first-order kinetics. Therefore, the rate of decay can be described by the same integrated rate equations and half-life equations that are used to describe the rate of first-order chemical reactions: lnAtA0=−ktlnAtA0=−kt and t1/2=0.693kt1/2=0.693k where A0A0A_0 is the initial amount or activity, AtAtA_t is the amount or activity at...

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
