Refer to the equation below. It gives off heat as a product. It is a/an _____ reaction. P4 + 5O2 -> P4O10 Exothermic Neutralization Endothermic decomposition
An ionic bond results from _____ electrons, while a covalent bond is a result of _____ electrons. Shared, transferred Transferred, shared Outer, inner Inner, outer
Two electrons are located 10-10 meters apart (the diameter of a typical atom). Identify the effect of the electrostatic force between the two electrons and its magnitude (size) compared to the gravitational force between the electrons. • The electrostatic force is repulsive and stronger than the gravitational force. • The electrostatic force is repulsive and weaker than the gravitational force. • The electrostatic force is attractive and stronger than the gravitational force. • The electrostatic force is attractive and weaker than the gravitational force.
The electrostatic force is repulsive and stronger than the gravitational force.

Clara wants to determine the volume of an ice cube. She places the cube into a graduated cylinder and waits for it to melt. Is this an accurate way to determine the volume of the ice cube? Yes, the melted ice cube will be the same volume as the frozen ice cube. No, the melted ice cube has a smaller volume than a frozen ice cube, because liquid water is denser than solid water. No, water vapor will be lost to the air during melting, which will change the measured volume of the two states. Yes, even though the volume of water in ice and liquid form is different, it is not enough to be measurable.
No, the melted ice cube has a smaller volume than a frozen ice cube, because liquid water is denser than solid water.

Each hydrogen atom has one electron and needs two to complete its first energy level. Since both hydrogen atoms are identical, neither atom dominates in the control of the electrons. The electrons are shared equally. This make H2 a Polar bonded covalent molecule Non-polar covalent molecule Polar covalent compound Non-polar ionic compound
