Answer:
Conduction is the transfer of heat between substances that are in direct contact with each other. Explanation:The better the conductor, the more rapidly heat will be transferred. Metal is a good conduction of heat. Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more.
Answer:
99Kg as the structure collapses at 100Kg how ever as a safe buffer the max weight allowed should be 90kg
Explanation:
Answer:
B) I2(s) is a stronger oxidizing agent than Al3 (aq), and Al(s) is a stronger reducing agent than I-(aq).
Explanation:
An oxidizing agent accepts electrons in a redox reaction and become reduced while a reducing agent looses electrons and become oxidized.
Hence in a redox reaction, oxidizing agents are reduced while reducing agents are oxidized.
Looking at I2 and Al3+, I2 is a better oxidizing agent since it has a reduction potential of +0.54V compared to -1.66V for Al3+.
Given the statements above, the converse must be true, that is; All is a better reducing agent compared to I-
Answer: Alkaline earth metals form basic oxides.
Explanation:
Elements of group 2 are also known as alkaline earth metals. For example, Be, Mg, Ca, Sr, Ba and Ra are all group 2 elements.
Being placed on the left side of periodic table, alkaline earth metals have large atomic radius but their radius is smaller than alkali metals (group 1).
When oxygen combines with a metal then it results in the formation of a basic oxide.
For example, MgO is a basic oxide of group 2 element.
Thus, we can conclude that alkaline earth metals form basic oxides.
