In order to apply the principle of conservation of mass to this reaction, we must prove that the mass on the left hand side is equivalent to the mass on the right hand side. In order to do this, we must first acquire the atomic masses of each substance involved. These are:
Fe - 56
O - 16
Now, we substitute these values into the equation:
4(56) + 3(2*16) = 2(56 * 2 + 16 * 3)
224 + 96 = 320
320 = 320
As we can see, the principle of conservation of mass holds true.
Then it is a pure substance, or an element.
Answer:
k=3.8
Explanation:
Because the temptuee is more.
Chemical change: is any change the results formation of new chemical substances
Physical changes: rearranged molecules but affect internal structures
Ethylene oxide is sporicidal. Option A is correct option.
<h3>What is ethylene oxide? </h3>
Ethylene oxide is defined as the cyclic ether or the simplest epoxide compound. It contains a ring structure consist of two carbon atoms and one oxygen atom. It is a colourless gas having fruity odour. Ethylene oxide is highly flammable and reactive and hence exposure which may result in lung injury or in respiratory irritation.
<h3 /><h3>Why ethylene oxide is sporicidal? </h3>
Ethylene oxide is a potent sterilant which can kill all life forms and having high sporicidal activity due to its property of high penetrating effects. It is also convenient to use and also effective at room temperature. Therefore, it is mostly used in hospitals to sterilize surgical equipment, instruments, and in disposable medical devices which are sensitive to heat and moisture.
Thus we concluded that ethylene oxide is sporicidal due to its property of high penetrating effects. Therefore, option A is correct option.
