Heat has been released or lost. Odor may be present. Absence of a substance may be converted to something else.
Answer:
Explanation:
PV / RT = n , n is number of moles
Total pressure = 96400 Pa
vapour pressure = 23.8 mm of Hg
= .0238 x 13.6 x 10³ x 10 Pa = 3236.8 Pa
Pressure of hydrogen gas P = 96400 - 3236.8
= 93163.2 Pa
n = 93163.2 x .0251 / 8.31 x 298
= .944 moles of hydrogen gas is produced
moles of magnesium reacted = .944
grams of magnesium reacted = .944 x 24 = 22.66 grams .
Wooahhhh pollution can affect the environment and urself pollited water can affect marine animals and can result them in extinction global warmning melts Antarctica and can cause floodigs and extinction there. This probably wont help but i just free styled lol
Goodluck
Answer:
Assuming the product is AlCl3
Assuming its 1008 g of metalic Al
It will yeld 4234 g of aluminium chloride.
Explanation:
Al molar mass is 26.98 g/mol, so in 1008 g of Al there is 37.36 mols of Al
The stoichometry ratio between Al and AlCl3 is 1:1, so 37.36 mols of Al would form 37.36 mols of AlCl3 if the reaction were complete, but only 85% yelds, so 1008 g of Al makes up to 0.85x37.36 mols of AlCl3 (31.76 moles)
AlCl3 molar mas is 133.33 g/mol, so 31.76 moles has 4234 g
Answer:
Total we want 48 titanium to make 12.0moles
