Answer:
42.38875878%
Explanation:
i divided 4.27 g from 1.81g using a percentage calculator but im not sure if its correct
A pure substance made up of different elements
hope this helped!!
If the reaction is a chemical change, new substances with different properties and identities are formed. This may be indicated by the production of an odor, a change in color or energy, or the formation of a solid.
Answer:
Most Likely A High Pressure Center
Explanation:
is most likely high pressure Center because on a weather map over the southern western Pennsylvania there's mostly high pressure over there. The descending air diverges and spreads out from the center and their is a Coriolis effect which causes the Diverging air to rotate in a clockwise direction.
Explanation:
It is given that volume of 
is 300 mL and molarity is 0.200 M.
Volume of NaCl is 200 mL and molarity is 0.050 M.
The chemical reaction will be as follows.
for 
is given as 
.
As, molarity is number of moles present in liter of solution.
Hence, moles of 
(aq) will be calculated as follows.
moles of (aq) = 
= 0.06 mol
![[Pb^{2+}]](https://tex.z-dn.net/?f=%5BPb%5E%7B2%2B%7D%5D)
= 
= 0.120 M
Mole of 
= 
= 0.010 M
Now, Q = ![[Pb^{2+}][Cl^{-}]^{2}](https://tex.z-dn.net/?f=%5BPb%5E%7B2%2B%7D%5D%5BCl%5E%7B-%7D%5D%5E%7B2%7D)
= 
= 
As, Q < hence, there will be no formation of precipitate.
