If you think of it endothermic is when there is energy needed for the reaction to occur and exothermic is when the reaction releases energy
1st law: Inertia, If you roll a ball it will not stop unless something blocks it by force.
2nd law: Force and Acceleration, when you’re riding a bike you are pushing the pedal with ur muscle which means you’re using force. Everytime you push the pedal the bike goes faster and faster which explains acceleration.
3rd law: Action and Reaction, If you run you’re feet pushes the ground (action) when your feet touches the ground it pushes you forward (reaction)
Ionic bonds are formed when a cation and an anion transfer electrons. The anion gains electrons from the cation to finish its shell, and is usually a nonmetal or a metalloid. A cation gives the anion its electrons to get rid of its partial shell. Cations are metals.
The answer would be Linear. in Carbon Dioxide, the two double bonds count as two pairs of electrons around the carbon atom, predicting linear geometry.
