Water will freeze at 0°C so the answer is b
Answer:
The answer to the question is option <u>D</u>
Answer:
Freezing
Explanation:
When a liquid goes to a solid, this process is called freezing.
Answer:
0.086
Explanation:
The formula for calculating the fraction of a covalent bond can be expressed as:
= exp (-0.25ΔE²)
![= exp[-0.25(E_{Al}-E_{p})^2]---(1)](https://tex.z-dn.net/?f=%3D%20exp%5B-0.25%28E_%7BAl%7D-E_%7Bp%7D%29%5E2%5D---%281%29)
from the equation above;
= the electronegativity of aluminum
= electronegativity of phosphorus
Using the data from periodic table figures;
= 1.5
= 2.1
∴
fraction of the covalent = exp[-0.25(1.5 - 2.1)²]
fraction of the covalent = exp(-0.09)
fraction of the covalent = 0.914
Now, the fraction of ionic bond will be = 1 - the fraction of covalent bond
= 1 - 0.914
∴
the fraction of bond that is ionic = 0.086
<span>Count the number of times it takes to empty a 100ml beaker using it. Divide the amount of water in the beaker by the number of times it took to empty it and you will have a rough approximation of how many mL your eye dropper will hold. Hope this helped!</span>
