Answer:
a simple covalent structure
Explanation:
its has a few non-metal atoms?
The temperature at which the process be spontaneous is calculated as follows
delta G = delta H -T delta S
let delta G be =0
therefore delta H- T delta s =0
therefore T= delta H/ delta S
convert 31 Kj to J = 31 x1000= 31000 j/mol
T=31000j/mol /93 j/mol.k =333.33K
Answer:
A. She can run the same distance in a shorter amount of time.
Explanation:
Speed can be computed with the formula:
![v = \dfrac{d}{t}](https://tex.z-dn.net/?f=v%20%3D%20%5Cdfrac%7Bd%7D%7Bt%7D)
Where:
v = speed
d = distance
t = time
So if you look at the formula, distance there tells you how far an object has traveled, and the time tells us how long it took to cover that distance. As you can see, speed and time are <u>inversely proportional. </u>This means that as one goes up, the other goes down. So if we reduce time travelling a certain distance, the speed increases.
