What is the difference between structural and ball and stick model?
What is the difference between structural and ball and stick model? A molecular formula uses chemical symbols and subscripts to indicate the exact numbers of different atoms in a molecule or compound. A structural formula indicates the bonding arrangement of the atoms in the molecule. Ball-and-stick and space-filling models show the geometric arrangement of atoms […]

How does electricity flow in a circuit draw an open circuit?
How does electricity flow in a circuit draw an open circuit? The electric circuit in which there is a gap in the connections between the terminals of the cell, wires and the bulb, etc is called an open circuit (or incomplete circuit). Electricity does not flow through an open circuit because there is a gap […]
What happens when stomata are open?
What happens when stomata are open? When stomata are open, water vapor and other gases, such as oxygen, are released into the atmosphere through them. A number of factors can affect the exchange of gases between a leaf and the atmosphere. What allows stomata to open and close? Specialized cells known as guard cells surround […]

What are chemical properties of steel?
What are chemical properties of steel? Alloy Steel Alloy steels (like carbon steels) contain both carbon and iron, but add additional elements such as silicon, nickel, chromium, manganese, or vanadium. The extra elements added are what provide the additional features and varied chemical properties compared to carbon steels. Is gold a metal? Gold (Au), chemical […]
