The answer is D: only the arrangement of atoms.
The smaller number is the number of protons, and the greater number is the mass.
Hypersaline
Explanation:
Mono Lake is a land locked body of water with a salinity of about 40 parts per thousand.
A lake is natural body of water surrounded by water.
Salinity is the amount of salt concentration in water body.
A salinity value of about 40 parts per thousand is said to be hypersaline.
This is salty water with a lot dissolved NaCl in it. it takes several years of dissolution of salt for a water body to have high salinity

Answer:
10.304 kPa
Explanation:
n=mol nitrogen (N2) gas=2moles
Temperature=T=310 K
Volume=0.5 L=0.5 dm3
R=8.31 J K−1 mol−1
From Gerenal gas equation we know that
PV=nRT
P=nRT/V
Putting the values
P=(2*8.31*3100/(0.5)
P=10.304 kPa
or P=10304 Pa
Answer: 36.53g
Explanation:
First we need to find the amount of NaCl that dissolves in 1L of the solution that produced 5M of NaCl
Molarity = 5M
MM of NaCl = 58.45
Molarity = Mass conc (g/L) / MM
Mass conc. (g/L) of NaCl = Molarity x MM
= 5 x 58.45 = 292.25g
Next, we need to find the amount that will dissolve in 125mL(i.e 0.125L)
From the calculations above,
292.25g of NaCl dissolved in 1L
Therefore Xg of NaCl will dissolve in 0.125L of the solution i.e
Xg of NaCl = 292.25 x 0.125 = 36.53g.
Therefore 36.53g of NaCl will dissolve in 125mL of the solution
