Answer:
i have taken environmental science so i can help
The overall order of a reaction is directly
related to the reaction mechanism of the reaction. The reaction mechanism is
defined by the reaction rate equation. In this case, we are given by the
equation, Rate=k. The order of this reaction is zero since the rate is
not dependent on the concentration of reactants or products.
Question in proper order:
Consider a solder containing 70%Pb 30%Sn, determine:
a. If the alloy is hypo- or hypereutectic
b. the composition of the first solid to form during solidification
c. the amount and composition of each phase at 1840 C
d. the amount and composition of each phase at 1820 C
e. the amount and composition of each phase at 500 C f. the eutectic composition and temperature ( 35 points)
Answer and explanation:
The Phase Diagram of Pb-Sn Alloy is given in the attached image
a. Pb-Sn alloy will have eutectic composition between 61.9% and 97.5% Sn, so the Pb-70%Sn alloy will have eutectic composition as it has 70%Sn
Answer:
The answer is "Option A"
Explanation:
At 3300 cm-1, the wide region is equal to OH. It is a possible group of alcoholic features that includes drugs. In the given choices option a is correct that's the structure can be defined in attachment file please find it, and the wrong choice can be defined as follows:
- In choice B, It is wrong because it doesn't include OH.
- In choice C, it uses the triple bond, that's why it is wrong.
- In choice D, it uses the two bonds, that's why it is wrong.
- In choice E, it uses the characteristic bond, that's why it is wrong.
