Answer: 1:4.69
Explanation:
The ratio can be expressed as:
Ua/Ub= √(Mb/Ma)
Where Ua/Ub is the ratio of velocity of hydrogen to carbon dioxide and Ma is the molecular mass of hydrogen gas= 2
Mb is the molecular mass of CO2 = 44
Therefore
Ua/Ub= √(44/2)
Ua/Ub = 4.69
Therefore the ratio of velocity of hydrogen gas to carbon dioxide = 1:4.69
which implies hydogen is about 4.69 times faster than carbon dioxide.
Fossil fuel emissions can create acid rain, which in turn increases the pH of ocean water, harming the organisms in the ocean.<span />
Answer:
salt is dull and brittle and conducts electricity when it has been dissolved into water, which it does quite easily.
Explanation:
transparent and colourless in crystalline form- rather like ice.
Answer:
Depends on conduction and the texture
Explanation:
it feels softer because tile is expose to the coldness in your building and carpet feels warmer because the texture of it
