Answer:
305.88 g
Explanation:
4 Al + 3 O₂ → 2 Al₂O₃
First, we <u>convert 6 moles of aluminum (Al) into moles of aluminum oxide (Al₂O₃)</u>, using the <em>stoichiometric coefficients</em>:
6 mol Al * = 3 mol Al₂O₃
Finally we <u>convert 3 moles of aluminum oxide into grams</u>, using its<em> molar mass</em>:
3 mol Al₂O₃ * 101.96 g/mol = 305.88 g
iONIC EQUATION:
2Na2+ +SO42-+2Cl-+ Ca2+---------- Ca2+ + SO42-+ 2Na+ +2Cl-
Explanation:
The balanced equation for the given reaction is:
Na2SO4+CaCl2======== CaSO4+2 NaCl
Na2SO4 will dissociate as 2Na2+ +SO4^2-
CaCl2 will dissociate as Ca2+ + 2Cl-
The two salts formed will precipitate.
we must consider that these substances are water soluble.
The ionic equation is:
2Na2+ +SO42-+2Cl-+ Ca2+----------- CaSO4+2NaCl
2Na2+ +SO42-+2Cl-+ Ca2+---------- Ca2+ + SO42-+ 2Na+ +2Cl-
Answer:
The reaction between nitrogen dioxide and carbon monoxide is
NO2(g)+CO(g)→NO(g)+CO2(g)
The answer is replication. The process of replication allows cells to reproduce and repair body tissue.
