V=d/t
v=18m/3sec
v=6m/s
or 6 meters per second.
Answer:
it is heterotrophic. it is unicellular. it does not have a nucleus.
Explanation:
The gram formula mass is another term for the mass of one mole of the substance which can be calculated by adding up the masses of the elements comprising the formula unit, molecules, etc.
a. Barium Fluoride (BaF2)
m = mass of Ba + 2(mass of F)
m = 137.327 g + 2(19 g)
m = 175.327 g
b. Strontium Cyanide (Sr(CN)2)
m = mass of Sr + 2(mass of C) + 2(mass of N)
m = 87.62 + 2(12) + 2(14)
m = 139.62 g
c. Sodium hydrogen Carbonate (NaHCO3)
m = mass of Na + mass of H + mass of C + 3(mass of O)
m = 23 + 1 + 12 + 3(16)
m = 84 g
d. Aluminum sulfide (Al2S3)
m = 2(mass of Al) + 3(mass of S)
m = 2(26.98) + 3(32)
m = 149.96 g
Well. NaOH is a base. That's the first thing you need to watch for.
So to find the pOH, you take -log(.0001)
that would be 4. So now you have the pOH and <u>you still need to find the pH
</u>To find pH from pOH, you take 14(the maximum pH,sorta)-pOH(in this case 4)
14-4=10 The pH of NaOH is 10
The answer would be B since it forms a solid
