Answer:
A. The NaCl dissociates into Na+ and Cl- ions, which are able to carry the charge.
Explanation:
This is because when dissolved in water (in aqueous form) ions can move freely and thus they can conduct electricity well. Water by itself is a poor conductor of electricity because it is neutral and therefore does not have the negative and positive charged required to conduct electricity.
Explanation:
Solids have definite shape and distinct boundaries as such the intermolecular forces between them is maximum
The balanced chemical equation for the <span>combustion of ethane is
2C</span>₂H₆(g) + 7O₂(g) → 4CO₂(g) + 6H₂O(l)
The stoichiometric ratio between C₂H₆(g) and CO₂(g) is 1 : 2
Hence,
moles of CO₂(g) produced = moles of reacted C₂H₆(g) x 2
= 1.00 mol x 2
= 2.00 mol
Hence, the correct answer is "C".
Answer:
Alpha particles, Beta particles, gamma rays, and neutrons
Explanation:
usually there's 2 ways radioactivity occurs: radioactive decay and ionization. radioactive decay breaks down the nucleas over time transforming the protons and neutrons into smaller particles alpha and beta with a little gamma radiation (gamma radiation is what was decaying). ionization is when the nucleas ejects neutrons as it's form of decay, leaving radioactive isotopes.
