Characterize each process as a physical change or a chemical change: (a) making ice cubes; (b) burning natural gas; (c) silver jewelry tarnishing; (d) a pile of snow melting; (e) baking bread.

Write two solubility rules that are used in this lab

Describe how you could use IR spectroscopy to distinguish between ethyl acetate and butyric acid. The IR spectrum of butyric acid should have a broad signal between 1650 cm-1 and 1850 cm-1. An IR spectrum of ethyl acetate will not have this signal.

What kind of energy is used to fry eggs

The molecules in a solid object A. flow freely around each other B. vibrate slowly C. are completely still all the time

How many moles of water can be obtained from the reaction of 4 moles of O2?

A solid white substance A is heated strongly in the absence of air. It decomposes to form a new white substance B and a gas C. The gas has exactly the same properties as the product obtained when carbon is burned in an excess of oxygen.

C). If 0.5 mole of oxygen (0,) reacted with hydrogen (H2), how many mole of water (H, 0) was produced from the reaction?

A cube has a depth of 10 cm. What is the volume of the cube? Or What is depth?
