Answer:
diffusion
Explanation:
Diffusion can be defined as the net movement of particles from a high concentration to a low concentration. This sounds like the most plausible word in this case.
Answer:
a
Explanation:
ability to cause change in matter or the capacity to do work
KCO₂
K₂C₂O₄
Explanation:
Given parameters:
Percent composition:
K = 47%
C = 14.5%
O = 38.5%
Molar mass of compound = 166.22g/mol
Unknown:
Empirical formula of compound = ?
Molecular formula of compound = ?
Solution:
The empirical formula of a compound is its simplest formula. Here is how to solve for it:
K C O
Percent
composition 47 14.5 38.5
Molar mass 39 12 16
Number
of moles 47/39 14.5/12 38.5/16
moles 1.205 1.208 2.4
Dividing
by smallest 1.205/1.205 1.208/1.205 2.4/1.205
1 1 2
Empirical formula KCO₂
Molecular formula
This is the actual combination of the atoms:
Molecular formula = ( empirical formula of KCO₂)ₙ
Molar mass of empirical formula = 39 + 12 + 2(16) = 83g/mol
n factor =
n factor = = 2
Molecular formula of compound = ( KCO₂)₂ = K₂C₂O₄

the change in heat associated with a chemical reaction or process the stability of a substance over a wide range of temperatures
Explanation:
A calorimeter is a device used to monitor the change in heat associated with a chemical reaction. It is also used to process the stability of a substance over a wide range of temperatures.
- Calorimeters are specially designed devices that are used to track heat changes accompanying any form of reaction.
- The are designed no to lose any amount of heat to the environment.
- Heat loss by radiation, conduction and convection have factored into the designing of a calorimeter.
- Heat loss in a calorimeter is gained by another body inside of it with no loss to the surroundings.
