Answer:
random internal motion of atoms and molecule
Explanation:
The primary cause of diffusion is the random internal motion of atoms and molecules.
Randomness of atoms and molecules results in diffusion.
- Diffusion is the movement of particles from a region of high concentration to that of lower concentration.
- Substances often tend to spread out over the concentration gradient.
- Therefore, they have this propensity to be randomized.
Answer:
6 HCl to 2 VOCl3
Explanation:
The coeffcients in front of the elements, represent moles. Therefore because the equation is balanced, you would evaluate your answer of the mole based off of what the question is asking. The question asked about the mole ratio of the two elements HCl to VOCL3. There is a number 6 in front of HCl which means that there are 6 moles of HCl, and there is a 2 in front of VOCL3 which means that there are 2 moles of VOCL3.
Therefore the correct answer will be 6 HCl to 2 VOCL3
Answer:
A. Alternating single and double bonds
Explanation:
Hydrocarbons i.e. hydrogen and carbon containing compounds, are grouped into two namely: aliphatic and aromatic hydrocarbons. Aliphatic hydrocarbons contains straight or branched chains of carbon and hydrogen atoms in their structure e.g. alkanes, alkenes etc.
On the other hand, aromatic hydrocarbons are cyclic hydrocarbons containing one or more cyclic rings. The benzene ring is the basis of all aromatic hydrocarbons and one characteristics of benzene is that it possesses an alternating single (-) and double bonds (=) in their structure.
Since benzene is a building constituent of aromatic hydrocarbons, an "alternating single and double bond" is a characteristics of aromatic hydrocarbons.
