D. Malleable, conducts electricity, high melting point, giant structure, metallic lattice
Explanation:
Copper is a metal with an atomic number of 29. This metal is soft and reddish in color which explains why it is very malleable(beaten to form various shapes without breaking).
All metals are good conductors of electricity including copper which is also a metal. Metals generally are insoluble in water. Copper also has a high melting point which is a characteristic of metals due to their giant structure and metallic lattice which makes it difficult to be broken down.
We need to find the amount of carbon dioxide gas in molecules of the gas.
We know that, 1 mole weighs 44 gram of carbon dioxide which contains number of molecules. It means that, number of molecules present in 44 grams of carbon dioxide molecule. So, number of molecules present in :
Hence, 7.675 grams of carbon dioxide is present in molecules of the gas.
Heat can be transferred from one place to another by conduction in solids, convection of fluids like liquids or gases, and radiation. A temperature difference in a system causes heat to move from higher to lower temperatures
molecules of the gas.
number of molecules. It means that,
