Answer:
Similar propoties is the answer
The curves absorb the food and sort of squish it and make it easier to digest then the food goes into the stomach acid and kind of burns and become and little softer<span> or in other words by allowing the stomach to stretch in order to accommodate large meals and get grip and move food during the digestion process. </span>
Answer : The half-life at this temperature is, 3.28 s
Explanation :
To calculate the half-life for second order the expression will be:
![t_{1/2}=\frac{1}{k\times [A_o]}](https://tex.z-dn.net/?f=t_%7B1%2F2%7D%3D%5Cfrac%7B1%7D%7Bk%5Ctimes%20%5BA_o%5D%7D)
When,
= half-life = ?
![[A_o]](https://tex.z-dn.net/?f=%5BA_o%5D)
= initial concentration = 0.45 M
k = rate constant = 
Now put all the given values in the above formula, we get:
Therefore, the half-life at this temperature is, 3.28 s
N2 + CaC2 = CaNCN + C
<span>As you can see, 1 mol of N2 can react completely with 1 mol of CaC2 and 1 mol of CaNCN will be obtained </span>
<span>It means 5 mol of N2 can react completely with 5 mol of CaC2 and 5 mol of CaNCN will be obtained </span>
<span>So, there are 7.5 - 5 = 2.5 odd mole of CaC2 after the reaction </span>
<span>And the mass of obtained CaNCN is </span>
<span>m = n*M = 5*80 = 400g</span>
Average speed (aka average velocity) is the change in displacement (distance) over the chance in time.
The average velocity of the baseball is 15 meters/sec
