Answer:
A skateboarder coming down the ramp.
When something is going up against ( up or <u><em>down</em></u> ) something it causes friction.
Hope this helps!
H₂:
M=2g/mol
m=10g
n = m/M = 10g/2g/mol = 5mol
O₂:
M = 32g/mol
m = 80g
n = m/M = 80g/32g/mol = 2,5mol
2H₂ + O₂ ⇒ 2H₂O
2mol : 1mol : 2mol
5mol : 2,5mol : 5mol
10g : 80g : 10g+80g=90g

I have heard they can use hair is stocking or nets to absorb the oil out of the water
Plant oil is differnent from trans fat, but plant oil is usually used for medical stuff.

For this problem, simply divide the mass of mercury you have by it's density.
100 g / 13.54 g/ml = 7.3855 ml
Since we only have 3 significant digits in 100., you need to round the result to 3 significant digits. So
7.3855 ml = 7.39 ml</span>
