PLEASE HELP ME Figure 12 shows the melting points of two substances, A and B, and the abilities
of the substances to conduct an electric current when solid and when molten.
One of the substances has an ionic structure and one has a simple molecular,
covalent structure.
Explain, in terms of bonding and the forces between the particles, the relative
melting points and abilities to conduct the electric current of substances A and B.

In this synthesis reaction what products will form

The table lists pressure and volume values for a particular gas. which is the best estimate for the value of v at p = 7.0 × 103 pascals?

In november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
