Explain what is meant by enthalpy?
BalasHapusEntalpi is a term in thermodynamics that states the amount of energy of a thermodynamic system. The enthalpy consists of energy in the system, including one of the five thermodynamic potentials and the function of the state, as well as its volume and pressure (an extensive quantity.) SI units of enthalpy are joules, but also the British thermal units and calories.
HapusTotal enthalpy (H) can not be measured directly. Just as with classical mechanics, only the changes can be judged. Entalpi is a thermodynamic potential, so to measure the enthalpy of a system, we must determine the reference point first, then we can measure the enthalpy changes ΔH. . Changes in ΔH are positive for endotherm and negative reactions to exotherms.
what is ozone?
BalasHapusOzone is a toxic gas so that when near the surface of the soil will be dangerous if inhaled and can damage the lungs. In contrast, the ozone layer in the atmosphere protects life on Earth because it protects it from ultraviolet radiation that can cause cancer. Therefore, scientists are very worried when they discover that chloro fluoro carbon (CFC) chemicals commonly used as a cooling medium and aerosol spray booster gas, pose a threat to this layer. When released into the atmosphere, these chlorine-containing substances will be broken down by the sun's rays that cause chlorine to react and destroy ozone molecules. Every single CFC molecule can destroy up to 100,000 ozone molecules. Therefore, the use of CFCs in aerosols is prohibited in the United States and other countries of the world. Other chemicals such as halokarbon bromine, and also nitrogen oxide from fertilizers, can also attack the ozone layer.
BalasHapusExplain about hydrogen and characteristic of hydrogen
BalasHapusHydrogen is the simplest of all chemical elements. [It is a colorless, odorless, tasteless gas that burns in the air to produce water. Has one of the lowest boiling points, -252.9 ° C (-423.2 ° F), and freezing point, -259.3 ° C (-434.7 ° F), of all elements.
HapusAdvertisement
A hydrogen atom contains one proton and one electron, making it the simplest atom that can be built. Because one proton in its nucleus, hydrogen is given the atomic number 1. As many as three isotopes of hydrogen exist. Isotopes are a form of element with the same atomic number but different atomic masses. Protium and deuterium are both stable isotopes, but radioactive tritium.
Hydrogen is the first element in the periodic table. The box is located at the top of the Group 1 standings in the periodic table, but is generally not considered a member of the alkali family, the other elements that make up Group 1. Its chemical properties are unique among the elements, and are usually considered to be in their own families.
Explain again about mass in chemistry
BalasHapusMass is a substance contained in an object in which the state is not affected by the surrounding gravity. This understanding should be underlined because many people are confused between the understanding of mass and weight, whether in chemistry or physics. The weight of the object is affected by gravity, while the mass is not. Well, the understanding of mass in this chemical tend to be more studied on changes in the composition of a substance substance of an object. Where in physics, the study of mass is more to change the object without forming a new substance or compound. Physics only reviews acceleration, velocity, gravity, weight, or distance change. From this, it can be expected that the field of learning about mass differs between chemistry and physics.
HapusWhat the function of temperature?
BalasHapusThe function of temperature is very much for life for example in the ice industry to make ice cream requires low temperature, in human life need sunlight hot temperature to dry clothes, then require high temperature to melt metal metal melt and so forth, if we ask the usefulness of temperature Tentusaja will be very much useful for nature, animals, plants and ourselves as human beings of course.
