I believe the ratio is 1:2
Answer:
Before a rollercoaster ride begins, an electric winch winds the cars to the top of the first hill. That can take a while, because some rollercoasters start off nearly 100m (330ft) in the air!
The winch has to use energy to pull the rollercoasters up the hill, but that energy doesn't simply disappear. The rollercoaster cars store it just by being up in the air—and the higher up they are, the more energy they store. They'll use the same energy to race back down the hill when the ride begins. Because they have the ability (or potential) to use in the future energy that was stored in the past, we call the energy they're storing potential energy.

<span>Molar mass is the mass of
one mole of a substance, it can be a chemical element or a compound. It is a
characteristic of each pure substance. We calculate it by adding up all of the masses of the atoms involved in the compound. We calculate as follows:
atomic mass total mass
C 17 12.01 g/mol 204.17 g/mol
H 19 1.01 g/mol 19.19 g/mol
N 1 14.00 g/mol 14.00 g/mol
O 3 16.00 g/mol 48.00 g/mol
------------------------------------------------------------
Molar mass = 285.36 g/mol

</span>6.02 x 10^24 molecules ( 1 mol / 6.02x10^23 molecules) ( 285.36 g/mol) = 2853.6 g morphine
An igneous rock is crushed into little shards of rock called sediment, the sediment is then packed together by other rocks or strong forces, that form together to make a Sedimentary rock.
- An ionic compound will not conduct electricity as a solid.
- It will conduct electricity when melted.
- Some ionic compounds are soluble. Their solutions in water also conduct electricity.
<h3>Explanation</h3>
A substance should contain charged particles that are free to move around in order to conduct electricity.
Ionic compounds contain an ocean of ions. They carry either positive or negative charges. Attractions between them hold them in a rigid lattice under the solid state. Those ions are unable to move. The ionic compound can't conduct electricity.
Melting the ionic compound will break the lattice. Those ions are now free to move to conduct electricity. Dissolving the compound in water will also free the ions. As a result, those solutions will also conduct electricity.
Conductivity under different states distinguishes between ionic compounds, molecular compounds, and metals.
- Ionic compounds conduct electricity when melted but not as a solid.
- Molecular compounds have no charged particles. They do not conduct electricity even when melted.
- Valence electrons in metals are free to move both when the metal is a solid and when it is melted. Metals conduct electricity under both solid and liquid states.
