The temperatures increased
I don't think it's any of the above. Because there is two double carbon bonds and it belongs to an alkene, it should be an ethene molecule.
Answer:
By the vibration of particles in a medium
Explanation:
For example, the energy in sound waves is transferred by the vibration of the molecules in air.
A is wrong. Electromagnetic radiation transfers energy through vibrating electric and magnetic fields.
B is wrong. Sound waves can transfer energy far from the ocean.
C is wrong. A combination of waves just makes a wave with a different shape.
The true ratio of atoms in a molecule or formula unit is called molecular formula
<h3>What is empirical formula?</h3>
This is the simplest formula that shows the ratio of the different atoms present in a compound.
<h3>What is molecular formula?</h3>
This is the formula of a compound which gives the true or actual ratios of the different atoms present in a compound
<h3>What is molar mass?</h3>
The molar mass of a compound is defined as the sum total of the molar masses of the different atoms present in the compound.
<h3>What is percentage composition?</h3>
This gives the proportion of the different atoms present in a compound.
From the above definitions, we can conclude that the correct answer to the question is molecular formula

Answer:
Uranium
Explanation:
The only natural element currently used for nuclear fission in reactors is uranium. Natural uranium is a highly energetic substance: one kilogram of it can generate as much energy as 10 tonnes of oil. Naturally occurring uranium comprises, almost entirely, two isotopes: U238 (99.283%) and U235 (0.711%).
