Answer:
10 ml
Explanation:
The graduated cylinder contains 19 ml of water before the silver pellet is placed inside. Afterwards, the graduated cylinder measures 29 ml of water. Therefore the pellet displaced 10 ml of water. ( 29ml - 19ml = 10ml )
Answer:
The solid layer of fat on top protects the broth from freezer burn. When I take the broth out of the freezer I use a butter knife to pop the fat cap off before defrosting. I do save chicken fat from soup and use it instead of butter or olive oil when I cook onions.

Answer : The formal charge on central Cl atom is -1.
Explanation :
The given molecule is, ![Cl^-_3](https://tex.z-dn.net/?f=Cl%5E-_3)
First we have to determine the total number of valence electrons in, ![Cl^-_3](https://tex.z-dn.net/?f=Cl%5E-_3)
As we know, chlorine has 7 valence electrons.
Total number of valence electrons in
= 3(7) + 1 = 22 electrons
Electrons used in bonding pair = 4
Electrons used as lone pair = 22 - 4 = 18
Now we have to calculate the formal charge on central Cl atom.
- Formal charge = Number of valence electrons of a central atom - (2 × Number of lone pairs) - Number of bond pairs
Formal charge on central Cl atom = 7 - (2 × 3) -2 = -1
Therefore, the formal charge on central Cl atom is -1.
The lewis-dot structure of
is shown below.
Answer:
D
Explanation:
I believe it is D. your kinetic energy would be at b. A, the cart would be going at a constant rate, because there is no hill or steep slope.
