without metal. The metals we use in our houses are mostly for keeping them sturdy. Though there is one problem we have when it comes to metals. That problem is that they rust. Metals rust when they are in contact with oxygen‚ and water. They rust much faster when they are in contact with salt water‚ and acid rain. We chose to see what would happen to various metals when they contacted with salt water. When the electrons move around in the salt water‚ it causes the metals to rust. The metals we chose

Are laboratory experiments useful? Laboratory experiments are easy to replicate and help to find how the Cause and effect of relationships can be established. Laboratory methods usually have High levels of control over extraneous variables. One of the major strengths of laboratory experiments is‚ control. The more variables you have control over‚ the easier it becomes to draw conclusions about the effect of the individual variable on the dependent variable. Laboratory experiments allow for high

observe the flame tests of some alkali and alkaline earth metal ion 2. Define ground state and excited state of an atom. Ground state- normal configuration of the electrons about the atom or the ion of an element; stable particle electrons are at lowest possible energy level Excited state- when stable particles are heated to very high temperatures some of the electrons leave their ground state and become “excited”; these electrons move to higher energy levels 3. What is flame test? Why do
