Loosely tape the toes together. Once you've decided on which two toes to tape together, grab some medical or surgical tape and loosely tape your injured toe to the uninjured one, perhaps using a figure-eight pattern for the most stability.
Hydrogen is a colorless, odorless, tasteless gas. Its density is the lowest of any chemical element, 0.08999 grams per liter. By comparison, a liter of air weighs 1.29 grams, 14 times as much as a liter of hydrogen. Hydrogen changes from a gas to a liquid at a temperature of -252.77Â°C (-422.99Â°F) and from a liquid to a solid at a temperature of -259.2Â°C (-434.6Â°F). It is slightly soluble in water, alcohol, and a few other common liquids.
gen atom. The chemical and physical properties of a substance refer to measurable or observable qualities or attributes that are used to distin-guish between different substances. Chemical properties describe how a substance interacts with other matter. Sodium and potassium, for example, react with water, but aluminum and gold do not. Physical properties are descriptive characteristics of matter. Examples of physical properties include color, density, conductivity, and malleability. Every substance will have a unique set of chemical and physical properties that can be used to identify it, because every type of substance has a unique atomic composition. It is often challenging to determine the identity of an unknown substance based on its chemical and physical properties.
