A wooden block of volume 5.24 x 10^(-4) m^3 floats in water, and a small steel object of mass m is placed on top of the block. When m=0.310 kg, the system is in equilibrium and the top of the wooden block is at the level of the water. (a) What is the density of the wood? (b) What happens to the block when the steel object is replaced by a second steel object with a mass less than 0.310 kg? What happens to the block when the steel object is replaced by yet another steel object with a mass greater than 0.310 kg?

if you're looking to install gigabit ethernet, what cabling system would you use?

A high temperature reaction vessel is charged with 0.5860 mol of iron powder and 35.1 L of oxygen gas at STP.

4Fe(s) + 3O2(g) yields 2Fe2O3(s)

After the reaction vessel is cooled, and assuming reaction goes to completion, what volume of oxygen remains?

what volume in liters on oxygen(O2) gas is standard temperaturepressure (STP) is required to react with 75.00g of Fe (molar mass=55.847g/mol)?
gas constant R=0.08206atm L/mol K

4Fe(s)+3O2(g)>2Fe2O3(s)

Iron and oxygen react to form iron(III) oxide; 4Fe(s)+3O2(g)-->2Fe2O3(s). Determine the limiting reactant in each of the following mxtures of reactants: a) 2.0 mol of Fe and 6.0 mol of O2. b) 5.0 mol of Fe and 4.0 mol of O2. c) 16.0 mol of Fe and 20.0 mol of O2.

Iron reacts with oxygen to produce iron (III) oxide.
4Fe(s) + 3O2(g) -> 2Fe2O3(s)

If 3.2 molecules of Fe react with excess O2, how many moles ofFe2O3 can be formed?

What mass of iron (Fe) would you need to react with 30.5 L of O₂ at STP?

4Fe_(s) + 3O_2(g) = 2Fe₂O_3(s)

4Fe + 3O2 ---> 2Fe2O3 How many Fe atoms are needed to react with 4.0 x 1023 molecules of O2?

What is data structure?

how many grams oxygen is needed to react with .41gFe

4Fe + 3O2 = 2Fe2O3

4Fe + 3O2 = 2Fe2O3

How many moles of oxygen molecules would be needed to react with111.2 grams of iron? How many grams of rust would result from thisreaction?

4Fe + 3O2 --> 2Fe2O3

If 5.0 Moles of oxygen O2 react, how many moles of Fe2O3 willform?

What is the mass of 5.0 moles of Fe2O3?
