Lichens are an examples of Symbiosis
The reaction between hydrogen and oxygen to form water is given as:
The balanced reaction is:
According to the balanced reaction,
4 g of hydrogen (
) reacts with 32 g of oxygen (
).
So, oxygen reacted with 29.4 g of hydrogen is:
Hence, the mass of oxygen that is reacted with 29.4 g of hydrogen is 235.2 g.
It can be made true by changing "cannot" to "can".
Answer:
0.026%
Explanation:
The Helium-4 is the isotope of the helium that has a mass equal to 4. The element has 2 electrons, so, the total radius of the electrons is 2*2.8 = 5.6 fm = 0.0056 pm.
So, the total radius of the particles is 0.0056 + 0.0026 = 0.0082 pm.
The percentage of the space that the particles occupy is the radius of them divided by the radius of the atom:
% = 0.0082/31 *100%
% = 0.026%
* 1 fentometer (fm) = 0.001 picometer (pm)
