How to solve determine the final temperature when 450.2 grams of aluminum at 95.2°c is placed in an insulated calorimeter with 6

0.0 grams of water at 10.0°c?

To solve this, we simply equate the change in enthalpy for the two substances since heat gained by water is equal to heat lost of aluminum. We know that the heat capacity of aluminum is 0.089 J/g°C and that of water is 4.184 J/g°C. Therefore:

450.2 (95.2 - T) (0.089) = 60 (T – 10) (4.184)

3,814.45456 – 40.0678 T = 251.04 T – 2,510.4

291.1078 T = 6,324.85456

<span>T = 21.7°C</span>

liubo4ka [24]

Answer:

4 miles north

Explanation:

Initially Scott travels 5 miles north at this point his displacement is 5 miles toward north

then he goes 3 miles south. which makes his displacement 2 miles (5 - 3 = 2) towards north as north and south are opposite directions.

finally he travels 2 miles due north.so his final displacement is

2 miles + 2 miles = 4 miles towards north direction
