All you have to do is explain the relationship between years and inches. The most rain was in 2004 with 10 inches and the least was in 1998 with 4 inches. In recent years there has been more rain than in the past. For the analysis just summarize that.
Answer:
3) Density multiplied by volume
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
So by rearranging this formula mass can be determine.
d = m/v
m = d×/v
Unit of mass when volume in mL and ddensity is g/mL
m = g/mL×mL
m = g
Example:
density = 5g/mL
volume = 3 mL
mass = ?
m = d×v
m = 5g/mL ×3 mL
m = 15 g
Answer:
-490.7 K
Explanation:
Given:
[Ni^2+]= 0.4 M
[Pb^2+]=0.002 M
∆V= -0.012 V
VNi= -0.250V
VPb= -0.126V
F= 96500 C
R= 8.314 JK-1 mol-1
n= 2
From
T= -nF/R [∆V-(VNi-VPb)/ln [Pb2+]/[Ni2+]]
T= 2(96500)/8.314[ (-0.012) -(-0.250) - (-0.126))/ln[0.002]/[0.4]
T= 23213.856(0.112/(-5.298))
T= -490.7 K
