Metallic bond
Metals are bound together by metallic bonds characterized by the sharing of free electrons among a lattice of the metal ions. This type of bonding gives metals unique properties such as strength, ductility, malleability, electrical and thermal conductivity, opacity, and luster.
This property of metal to be flattened and shaped is called malleability. When stress is applied to the metal, its atoms merely roll or slide over each other into new positions while keeping the metallic bond intact. The bonds do not break, thereby allowing the metal to be flattened out instead of crumbling or breaking into pieces.

Answer:
When an apple is cut or bruised the oxygen goes into the injured plant tissue. It begins to oxidize from the reaction of the enzymes and oxygen. The apple produces melanin to protect it causing it to brown. Using vinegar and lemon juice help stop the browning because lemon juice has a compound that reacts with oxygen before the oxygen can react with apple. Also, vinegar and lemons are very acidic which slows the browning reaction.

The pressure in mmHg forecasted today is 783 mmHg
Pressure is the force acting perpendicular to the area of a surface. Pressure is given by:
Pressure = Force/Area
The pressure of a gas is the force exerted on the walls of its container by the gas. Pressure can be measured in atm, mmHg, etc.
1 atm = 760 mmHg
1.03 atm = 760 mmHg per atm * 1.03 atm = 783 mmHg
Therefore the pressure in mmHg forecasted today is 783 mmHg
