•  Negative charges repel each other so valence shell electrons are trying to separate.

• This is a linear snape
• Furthest away
• 2 thing around a central atom
• Doesn't have to be singular bonds

• This is a trigonal planner
• Doesn't have ro be singular bonds
• 3 thing around a central atom

• Take the two atoms on top into consideration
• 3 things arounds the central atom
• Similar to trigonal planner
• This molecule is called a "bent" molecule

• Tetrahedral molecule. All amples  
• 4 things around the central atom

• Trigonal pyramidal
• The atom on top is replaced by an unshaved electron pair
• The atom on top pushes harder, less angles

A 5.00 g strip of gold (specific heat = 0.129 J g–1 K–1) and a 5.00 g strip of nickel (specific heat = 0.444 J g–1 K–1), both initially at 25°C, are dropped into a beaker of water that is initially at 70°C. Which one of the following statements is true after thermal equilibrium is reached?

a. Both metal strips will absorb the same amount of heat energy and have the same final temperature.

b. Both metal strips will absorb the same amount of heat energy, but the nickel strip will have a higher final temperature than the gold strip.

c. The gold strip will absorb more heat energy than the nickel strip, but the two strips will Have the same final temperature.

d. The nickel strip will absorb more heat energy than the gold strip, but the gold strip will have a higher final temperature than the nickel strip.

e. The nickel strip will absorb more heat energy than the gold strip, but the two strips will have the same final temperature.
