Answer:
it depends on mass and speed
Answer:
hydrogen is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas
Explanation:
Hydrogen is part of the Noble gas family
<span>V = 150.0 mL = 0.15 L
c = 1.70 M
</span>m=?
For the purpose, the equation for molar concentration is necessary:
c=n/V
From the equation we can determine the number of moles:
n= cxV = 1.70M x 0.15L = 0.255 mole
Now we can calculate the mass:
m = nxM = 0.255 x 119= 30.34 g is necessary
Answer:
False
Explanation:
In physical change chemical composition stay the same, does not change.
The name of the acid whose formula is Hi is Hydrogen iodide
