2Al+Zn(NO3)2=2Al(NO3)3+Zn net ionic equation?
The equation given above is wrongly balanced, so I have to correct it first. $Al^@$ + $Zn(NO_3)_2$ = $Al(NO_3)_3$ + $Zn^@$ (unbalanced) Tallying the atoms based on subscripts, left side:...

Using the equation, $Fe_2O_3 + 2Al -> 2Fe + Al_2O_3$, how many grams of $Al$ are needed to completely react with 135 grams of $Fe_2O_3$?
The coefficients in the equation provide a molar ratio between the chemical species in the equation, so you must first convert the mass of iron (III) oxide to moles of...

How many moles of aluminium cations are present in $"5.1 g"$ of aluminium oxide?
The idea here is that each formula unit of aluminium oxide, $"Al"_color(red)(2)"O"_color(blue)(3)$, consists of two aluminium cations, $color(red)(2) xx "Al"^(3+)$ three oxygen anions, $color(blue)(3) xx "O"^(2-)$...

How many grams of aluminum are required to produce 8.70 moles of aluminum chloride in the reaction $2Al + 3Cl_2 -> 2AlCl_3$?
The balanced chemical equation represents ratio in which the chemicals combine, and in this case illustrates that $2 mol Al$ produces $2molAlCl_3$, hence these 2 chemicals are in a $1:1$...

How do you find the maximum mass of aluminium that can react with 0.5 moles of HCI?
2Al + 6HCI - > 2Al2Cl3 + 3H2
Step 1. Start with the balanced equation. The balanced equation is $M_text(r):color(white)(m) 26.98$ $color(white)(mmmll)"2Al" + "6HCl" → "2AlCl"_3 + "3H"_2$ Step 2. Calculate the moles of $"Al"$. $"Moles of...

How many grams of hydrogen are necessary to react completely with 2.3 moles of nitrogen, in the reaction N2+3H2 = 2NH3?
Starting from moles of nitrogen, we'll find the moles of hydrogen using the stoichiometric coefficient (the number in front of in the balanced equation). then, from the moles...

The balanced equation shows the reaction between aluminium hydroxide and hydrochloric acid to form aluminium chloride and water: Al(OH)3 + 3HCl = AlCl3 + 3H2O. 1 mole of aluminium chloride was formed, what mass of aluminium hydroxide was formed?
I'll assume you mean what mass of aluminum hydroxide reacted. We can use the coefficients of the equation to determine the number of moles of $"Al(OH)"_3$ that react, knowing that...

35.0 grams of thionyl chloride is placed in a glass containing 500.0 grams of water. After the reaction is complete how many grams of water will remain unreacted? How many grams of the thionyl chloride will remain unreacted?
Thionyl chloride reacts quantitatively (and violently) with water as represented by the following reaction: $SOCl_2(l) + 2H_2O(l) rarr SO_2(g)uarr + 2HCl(aq)+Delta$ $"Moles of thionyl chloride"=(35.0*g)/(118.97*g*mol^-1)=0.294*mol.$ And CLEARLY, thionyl chloride is...

In the equation, $2Al + 2Fe^(3+) + 3O^(2-) -> 2Fe + 2Al^(3+) + 3O^(2-)$m which element has been reduced?
Reduction involves a formal GAIN of electrons. Oxidation involves a loss of electrons. In the reaction above, clearly ferric ion, $Fe^(3+)$, has been REDUCED. The correct reaction is: $Al +...

Given the equation: $2Al + 3Cu_2 ->2Al^(3+) + 3Cu$. What is the reduction half-reaction?
And the oxidation reaction......... $Al(s) rarr Al^(3+) + 3e^-$ And cross-multiplying to remove the electrons......... $2Al(s) + 3Cu^(2+) rarr 2Al^(3+) + 2Cu(s)$ Is charge balanced? Is mass balanced?
