Since the compound has 1.38 time that of oxygen gas at the same conditions of temperature and pressure, we have the relationship:
MW/MWoxygen = 1.38
MW = 44.16
Since there is water formed during the reaction, the formula of the compound must be:
XaHb
where a and b are the coefficients of each element.
If the compound reactions with oxygen forming water and an oxide of the element X, the combustion reaction must be:
XaHb + ((2a + (b/2))/2) O2 = a (XO2) + (b/2)(H2O)
Using dimensional analysis:
10 (1/44.16) (b/2 / 1) (18) = 16.3
Solving for b:
b = 8
The compound now is XaH8. Most probably, the compound is C3H8 since it has a molecular formula of 44 and it reacts with O2 to form water and CO2.
Acids are corrosive, which means they 'eat away' at other materials.
Answer:
Answer is option B . This is because water is said to be highly permeable to the underground soil and thus nourishes it , whereas capillary action will make the water flow upward sllowly , but the water is going underground so it is permeability. Also soil is porous too , but that's only if the water is in the soil , here the water is caused to go underground by some force , so porosity isnt the right option
Explanation:
I think it is B
Explained answer:
Glaciers dissolve and melt because they are made out of ice
Gamma rays
Explanation:
Gamma rays is a form of electromagnetic radiation. It has zero mass and no charge.
Most radiations are particles but gamma rays are not particles they are mere rays.
- They have an energy range between 10KeV and 3Mev
- The range of gamma rays is not definite but it is very long.
- The intensity of gamma rays for any medium decreases exponentially from the source.
- Gamma rays are ionizing radiations
