You mix 25.0 g each of an acid and a base in a beaker. Both have an initial temperature of 57.0°C. The ensuing reaction is exothermic (releasing 1.80 kcal of heat). Use the Heat Equation to find the final temperature of the mixture? The Specific Heat of the acid and base are 1.00 (cal/g°C) a)36.0°C
b)51.0°C
c)57.0°C
d)81.0°C
e)93.0°C

A48 g piece of ice at 0.0 ∘c is added to a sample of water at 7.4 ∘c. all of the ice melts and the temperature of the water decreases to 0.0 ∘c. how many grams of water were in the sample?

Scientists often have to deal with numbers that are either very large or very small. for example, the radius of the sun is approximately 696,000 kilometers, while bacterial cells are as small as 1.9 × 10-4 millimeters. express each number in an alternate form.

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.
