A substance through which an electrical current flows poorly would be said to be a poor conductor. That is, the substance has a low conductance (or conductivity). There’s a nuance between the two terms, but it shouldn’t matter for our purposes.
Since such a material resists the flow of electric charge, the material can be said to have a high resistance (or high resistivity).
Mathematically, resistance and conductance are reciprocals of one another; a low conductance implies a high resistance, and a high conductance implies a low resistance.
Answer:
CaCO3 -> CaO + CO2
Explanation:
Woahhhh, did you balance it yourself just then?
One thing about mercury is that Mercury is the smallestplanet in the Solar System.
To determine how much water can form would depend on what the acetic acid is reacting with. However, a very common reaction of acetic acid that leads to the formation of water is the condensation that occurs during the esterification process. We can react acetic acid with an alcohol, such as methanol, and form the ester and water.
CH₃CO₂H + CH₃OH → CH₃CO₂CH₃ + H₂O
The mole ratio of water to acetic acid is 1:1. We can now use the mass of acetic acid to find the moles, which we can convert to moles of water:
5.10 g CH₃CO₂H / 60 g/mol = 0.085 mol CH₃CO₂H x 1 mol H₂O/1 mol CH₃CO₂H = 0.085 mol H₂O
0.085 mol H₂O x 18 g/mol = 1.53 g H₂O
In the reaction provided, assuming the reaction goes to completion, 5.10 g of acetic acid can form 1.53 g of water.
