Answer:
Nothing.
Step-by-step explanation:
Both Al(OH)₃ and CaSO₄ are insoluble in water, so their ions cannot come into contact and react.
245gLiBr/86.84(molar mass of LiBr)=2.82128 moles
Answer:
matter im pretty sure sorry if its wrong
Explanation:
based on the property of conserving matter, matter can not be created or destroyed
I’m pretty sure it is number of protons
Answer:
N2 = 588.95 mm Hg
O2 = 158.36 mm Hg
Ar = 6.787 mm Hg
Explanation:
Their percentage represents their mole fraction.
N2= 78.1% = 0.781
O2 = 21.0% = 0.21
Ar = 0.9% = 0.009
Barometric pressure is 754.1 mm Hg
Partial pressure for each will be,
For N2 = 0.781 x 754.1 = 588.95 mm Hg
For O2 = 0.21 x 754.1 = 158.36 mm Hg
For Ar = 0.009 x 754.1 = 6.787 mm Hg
