The molecules vibrate when the substance is heated, and the shape of the substance begins to form a different shape. For example: when you hear up metal it will melt becuase its molecules are changing and moving.

Molecule movement. Ice is so hard because molecules are not moving, and the space between them are small. Hot water has bigger space between molecules that are always in motion.

Explain polarizing power with ionic radius​
shutvik [7]

Answer:

Polarizing Power is the basis of Fajan's rules of covalent character generally in ionic compounds.

Charges and radius are a function of Polarizing Power, because the higher the charge is, the larger the polarizing power is for cations with the same radius. Also the smaller the radius is, the larger the polarizing power is for cations with the same charge.

Carbon dioxide enters the atmosphere by natural processes and from human activity. Why is the latter a cause of concern?
Angelina_Jolie [31]

By removing long-buried fossil fuels and burning them to produce electricity, human activities have drastically disrupted the natural carbon cycle and released CO2 into the atmosphere. The burning of fossil fuels like coal, natural gas, and oil, including gasoline, is responsible for 85% of all human-produced carbon dioxide emissions.

reductions in atmospheric oxygen concentration and the proportion of other carbon isotopes (14C and 13C) have been observed. Because the natural mechanisms that may restore the balance are too slow relative to the rates at which human activities are adding CO2 to the atmosphere, the extra CO2 from burning fossil fuels and deforestation has upset the equilibrium of the carbon cycle. As a result, a sizeable portion of the CO2 produced by human activity builds up in the atmosphere, where part of it will stay for thousands of years rather than just a few decades or centuries.

What is the Noble gas notation for mercury (Hg)?.
lapo4ka [179]
The noble gas notation of an element includes a noble gas as a condensed way to describe the electronic configuration of an element. IN this case, the nearest noble gas is xenon with an atomic number of 54. Hg's atomic number is 80 so we need 26 more. In this case, after [Xe], the configuration starts with 6s². Hence to complete the configuration the answer is  [Xe] 6s2  4f14 5d10
