Volume is 3 dimentional
cm is 1 dimentional: legnth
L=liters=volume=cubic meter
ml=mililiter=volume=cubic centimeter
cm^3=mililiter
cm is the answer
weight is the measurement of the amount of gravity of an object, it changes depending on where you are (on moon, something has less weight than on earth)
mass is how much matter is in something, doesn't matter where you are (on moon, still same mass as on earth)
FALSE
It's shifted up two units. You can tell this by mapping the point of change as the origin in the original graph and (0,2) in the second graph.
Answer:
There are 10⁻⁷ hydrogen ions in one-liter water
Step-by-step explanation:
Hi there!
a. If the pH = 7.0, then:
-log(H) = 7.0
multiply both sides of the equation by -1
log(H) = -7.0
Apply 10ˣ to both sides
10^(log (H)) = 10⁻⁷
(H) = 10⁻⁷
There are 10⁻⁷ hydrogen ions in one-liter water.
Why 10^(log (H)) = (H)?
Let´s consider this function:
y = 10^(log x)
(Apply log to both sides)
log y = log 10^(log x)
(Apply logarithmic property: log xᵃ = a · log x)
log y = log x · log 10
(log 10 = 1)
log y = log x
y = x
(since y = 10^(log x) and y = x):
10^(log x) = x
That´s why 10^(log (H)) = (H)
