A chemist takes 50-gram sample of sulfur powder that has a melting point of 115.2 °C. What is the melting point of a 100-gram sa
Viktor [21]

Answer:

115.2 °C since melting point is an intensive property  

Step-by-step explanation:

The melting point of a substance does not depend on how much you have.

For example, the melting point of water is 0 °C, whether it is an ice cube from the refrigerator or in the frozen pond outside.

The freezing point of a substance is an <em>intensive property</em>.

Thus, the melting point of 100 g of sulfur is 115.2 °C because melting point in an intensive property.

Finger [1]

Answer:

Check explanation section.

Explanation:

Yes, that is true. Sodium with chemical symbol Na belongs to the group 1 on the periodic table. Group 1 elements are known as Alkali metals. Other elements in the group are Caesium, lithium, Rubidium, francium and potassium.

Neon belongs to the noble gas of group 8/0.

Sodium is very reactive and and good conductor of electricity. Sodium reacts with water for the production of hydrogen (NB: this reaction is vigorous).

2Na(s) + 2H2O ------------> 2NaOH + H2(g).

They can react with nonmetals such as the halogens. For instance;

Na + Cl2 -------------------------------> 2NaCl.

Sodium is ductile and have low melting point( but high compared to neon).

Neon is not active chemically and it has no odour and no color
