The given statement is false.
The electrons have both wave and particles like properties. It was postulated by De Broglie that electrons have wave nature and suggested that all the matter exhibit wave characteristics. This concept is called the De Broglie hypothesis.
Like all the elementary particles, the electrons possess the characteristics of both waves and particles, in the sense that they can collide with other particles and be diffracted like light.
For this item, the <span>∆t will be the value of temperature difference that the substances will experience once subjected to same amount of heat. The heat is equal to,
H = mcp</span><span>∆t
where H is heat, m is mass, cp is specific heat, and </span><span>∆t is temperature difference.
The compounds given, despite having the almost the same molecular weight, will have different </span><span>∆t because of the different intermolecular forces present especially in the alkyl groups present. </span>
Answer:
You confirm the units involved, which would make you to understand the factors required.
Explanation:
Conversion of units is a process in which a given unit of a physical quantity is accurately transformed into another. Example, when the mass of a substance in grams is converted to kilograms. Or conversion of a given quantity of substance from liters to gallons.
When conversion is required, the first thing to do is to determine the units involved. That is, which unit do you want to convert to the required unit. This would give the understanding of the factors that are needed.
If two substances react and the temperature of the mixture decreases, the reaction is endothermic<span>. If two substances react and the temperature of the mixture increases, the reaction is </span>exothermic<span>. A chemical reaction involves the </span>breaking<span> of bonds in the reactants and the forming of bonds in the products.</span>
Hydrophilic - attracted to water
Hydrophobic - resists water
