such as chlorine, oxygen or sulphur. After reacting with the other element, the Hg is converted into an inorganic mercury compound, like mercuric chloride, mercuric oxide or mercuric sulphide. This generally takes the form of a white crystalline powder. ...
Mercury measures 13.534 grams per cubic centimeter. That's thirteen and a half times more dense than water, which scientists have assigned a density of 1.0. What Is Density? Density is the measurement of an object's mass divided by its volume. Density cannot be measured directly; instead, a...
An element has a density of 19.5 g/cm3. What is the radius of a sphere that has a mass of 60 kg of this material? A solid metal sphere has a volume of 4.2 ft^3. The mass of the sphere is 155 lb...
If the atmosphere can support a column of mercury 760 mm high at sea level, what height of a hypothetical liquid whose density is 1.40 times the density of mercury could be supported? If the atmosphere can support a column of mercury 762 mm high at sea level, what height of water could...
It is not a case of size whether an object is a moon or a planet or an asteroid,the MoonGanymede, which orbits around Jupiter is larger than Mercury but is not a planet as mentioned, it orbits a planet and not a Star. The difference between an asteroid, a planet and a moon is tha...
When an object or person is placed in water, gravity can still act on the object, but only if an equal volume of the water can go upwards, against gravity. This is known as displacement and as a result, gravity has to choose which element it will pull down, the water, or the object...
Warming-up What Are Substances Composed of? The theory of four elements As recently as a few thousand years ago,western scientists considered the whole earth to be made of 4 elements:Earth,Air,Fire,and Water.Air was the underlined element:this single substance made up everything in the world...
Density:The density of a substance defines the ratio you get when you divide its mass by its density. The density of a substance is unique to that particular substance, and thus can be used to identify a substance. The density can also be used to convert between mass and volume ...
The intermolecular spaces are tiny. The intermolecular forces are enormous. The dimensions of solids do not increase in large proportion on heating or cooling. When two solids are kept in contact with one another, they do not mix, and they do not diffuse. The density of solids is generally ...
The density of dry air is 1.29 grams per liter (0.07967 pounds per cubic foot) at 32 degrees Fahrenheit (0 degrees Celsius) at average sea-level barometric pressure (29.92 inches ofmercuryor 760 millimeters). Atsea leveland at 15 degrees C, the density of air is 1.225 kg/m3. This is ...
