Answer:
its d, the explanation for this is because I need some more points so ima go ahead and just spam random questions
Answer:
Phosphorus has a low melting point because the intramolecular forces holding it together is London Dispersion Forces.
Explanation:
London Dispersion Forces (LDF) are the weakest intramolecular forces. You don't need to break the covalent bonds, but rather the Van Der Waals' Forces. If LDF are the weakest forces, then the melting point is low.
Answer:
Aluminium (Al): (3*2)+(5*2)=16
Sulphor (S): (3*1)=3
Oxygen (O): (4*3)+(3*1)=15
Answer:
The temperature differs in 25 degrees on the Celsius scale
Explanation:
The relationship between temperatures on the two scales is:
So, if the temperature recorded differed by 45, then the degrees on the Celsius scale can be calculated as follows:
<u>Since F₂ - F₁ = 45, we have:</u>
Therefore, the temperature extremes differ in 25 degrees on the Celsius scale.

Answer:
compound
Explanation:
A compound contains more than one element.
Methane's chemical formula (CH4) indicates that it consists of one carbon atom and four hydrogen atoms.
Therefore, methane is a compound.
