What is the chemical formula for exhaled air?
The typical composition of exhaled air is about 18% O2, 78% N2, and 4.0% CO2
Is air sensitivity a physical or chemical properties?
It is a chemical property as air sensitive compounds react with oxygen or air to yield a different compound. Physical properties don't alter the composition of the compound but rather the behaviour through different molecular arrangement.
How does air temperature change with atmospheric composition?
The composition of air depends upon altitude.
What is the rate at which a candle burns in millimeters per minute?
That depends on the density, cross-sectional area, and chemical composition of the candle, and on the turbulence in the air surrounding it.
What is the composition of gases found in inhaled air?
gas composition in air is the sum of the gas individual element and that of the air i.e oxygen and nitrogen
What is the best storing system for cement?
air entraining room
What is Chemical name of cement?
The very basic chemical compound of cement is Calcium Hydroxide. The calcium hydroxide is mixed with water and the carbon dioxide in the air acts on it to harden it.
Why air is a compound?
Air is not a compound, because its chemical composition varies with time and place. Air is a mixture instead.
Why there is no such a thing as chemical formula of air?
Because air is a composition of all kinds of gases and is different everywhere.
What is bycol?
Bycol Clear is an air-entraining admixture used to improve the workability of brickwork mortars and concrete mixes.
What is the chemical formula for exhaled air?
The typical composition of exhaled air is about 18% O2, 78% N2, and 4.0% CO2
Is the silica sand good for concrete mixed and can you help me about chemical ingredient that help increase concrete durability and strength?
I will pass on the silica sand item and the strength increases. Try the portland cement association site. As for durability, the most success I know of has been the use of air entraining agents in concrete. My experience is in roads and bridges. A 6% air entrainment (one was called Darex) dramatically improves the ability of concrete to withstand freeze-thaw cycles. Test specimens that I saw had been put through thousands of cycles. The non-air sample was pitted, spalled, pockmarked while the air mix looked pristine. The amont of air entraining agent is critical because it reduces the strength of the mixture (solid sand,and stone particles have been replaced by microscopic air voids). There are hundreds of ways to improve strength and early development of strength. The biggest effect is overuse of the chemical h2o. Also, in the long run air entrainment maintains strength longer because of the durability increase.
Is the air is often blended into ice cream to give it a lighter texture a physical or chemical and why?
It is a physical process because the chemical composition remain unchanged.
What is the chemical composition of a flame?
A flame is pure energy so it has no real chemical composition except from the chemical compositions of the oxygen and fuel (usually hydrocarbons) needed for it to burn. A flame requires fuel, oxygen and heat energy, although it gives off light and heat energy as well. The act of burning is reacting the fuel with oxygen in the air but the flame itself has no chemical composition.
Is air sensitivity a physical or chemical properties?
It is a chemical property as air sensitive compounds react with oxygen or air to yield a different compound. Physical properties don't alter the composition of the compound but rather the behaviour through different molecular arrangement.
How chemical weathering affect rock?
Chemical weathering affects rocks rain, wind or ice . Chemical weathering is the process that changes the composition ( the inside) of rocks on the earth surface.
How do animals and plants of the ocean affect the chemical composition of seawater?
The exact same way you affect the air as a human being, in theroy.
