- I: Nucleolus
There is no function/description that accurately matches up with the vacuole. In fact, there are 13 organelles provided and only 12 functions/descriptions listed; presumably, the description/function of the vacuole is the one that is missing.
Answer:
3 is decomposition
4 is double replacement
Explanation:
In decomposition reactions, a compound (two or more elements) are broken down into singular elements.
Double replacement reactions have two different compounds, one element from a compound switches with another element in the other compound.
Answer:
d = PM / RT
Explanation:
Density can be measure from,
PV = nRT
in this equation
P = pressure
V = volume
n = number of moles
R = general gas constant
T = temperature
It is known that,
number of moles = mass/ molar mass
n = m/M
We will put the n= m/M in PV= nRT
PV = m/M ×RT ......... (1)
density = mass/volume
d= m/v
By rearranging equation (1)
P V/m = RT/M
P = m/V×RT/M
P = dRT/M
d = PM / RT
