First step is to get the mass of water molecule in grams:
From the periodic table:
molar mass of hydrogen is 1
molar mass of oxygen is 16
molar mass of a water molecule = 2(1) + 16 = 18 gm
Now, to convert the gm into amu, all you have to do is multiply the gm you got by Avogadro's number as follows:
mass of water molecule = 18 x 6.22 x 10^23 = 1.1196 x 10^25 amu which is approximately 1 x 10^25 amu
Answer:
law of multiple proportions
Explanation:
The law of multiple proportions states that, if two elements A and B, combine to form more than one chemical compound. Then the various masses of one element A, which combine separately with a fixed mass of element B are in simple multiple ratio.
We can see that the ratio of oxygen that combines with carbon in the two compounds( A and B) is 1:2. This demonstrates the law of multiple proportions.
The substances A and B must be CO and CO2 respectively.
This example is describing the Chromatography method.
Answer:
Hydrogen atoms fuse together to form helium atoms. This releases a huge amount of energy in the form of Kinetic energy of the alpha particle and Electromagnetic radiation.
Explanation:
Nuclear Fusion is the Nuclear process in which the energy is produced when two lighter elements are collided together which are having some kinetic energy in them after that the two lighter nuclei will fuse together into a single heavier nuclei. This is opposite to what happens in Fission process in which the breaking up of atomic specie happens.
Both Nuclear Fission and Nuclear fission occurs with the release of massive amount of energy.
There are conditions for nuclear fusion to happens like, it requires 100 million's kelvin of temperature, also fusion will occur when the pressure is very high because increased pressure will result into squeezing of the atomic specie and hence they will fuse.
When the Hydrogen atom fuse together to form helium atoms. This release a huge amount of energy in the form of Kinetic energy of the alpha particle and Electromagnetic radiation.
