Stomach acid buildup can occur for many reasons, including heredity, diet and your body's natural acidity, and excessive stomach acid can occur in both isolated and chronic cases.
The alkali metals, halogens and noble gases are three important groups in the periodic table. The alkali metals are soft, reactive metals. They react vigorously with water and become more reactive as you go down the group.The halogens are reactive non-metals.They become darker as you go down the group.Their reactivity decreases as you go down the group and their boiling points increase. A more reactive halogen will displace a less reactive halogen from solutions of its salts.he halogens are reactive non-metals. They become darker as you go down the group. Their reactivity decreases as you go down the group and their boiling points increase. A more reactive halogen will displace a less reactive halogen from solutions of its salts.
Matter can be uniquely identified by using two main categories of properties, they are physical and chemical. Physical properties of matter refer to characteristics of a substance that can be observed WITHOUT changing the actual âmakeupâ of a substance. Some physical properties include mass, volume, color, boiling point, how hard a substance is, and even taste. Many things that we come in contact with can be accurately identified by just using some physical properties that we observe about it.
