The cyclopropane  concentration after 25 minutes : [A]=0.549 M

<h3>Further explanation</h3>

Given

a rate constant k = 6.7x10⁻⁴ /s

Initial  concentration : 1.5 M,

t = 25 min = 1500 s

Required

The final concentration

Solution

For first-order reaction :

[A]=[Ao]e^(-kt)

or

ln[A]=-kt+ln(A0)

Input the value :

ln[A]=-6.7 x 10⁻⁴ x 1500 + ln 1.5

[A]=0.549 M

Which of the following materials is useful for making molds because it has a low melting point?
inessss [21]
<span>Molds are created to achieve a specific design of a material. These materials either came from a process of having a higher or lower temperature. Therefore, the molder must have thermal resistant properties. Low melting points means that the material to be shaped came from a cooler process. Wood and metal have higher thermal conductivity and therefore can easily be cooled. The wax can turn really hard and can be unbreakable when present in colder materials due to the lipids present in it. Clay however can become a mold because of its low melting point.</span>
