• ### Easter Bunny Fish Names?

I getting the kids that I watch a fish for easter (there out of town so its from the easter bunny). I want to name it something that pertains to easter. Not necessarily biblical, but something cute and creative (example: Eggbert) Help and ideas?!

• ### limiting reactants help?!?

One industrial process for producing nitric acid begins with the following reaction;

4NH3+5O2--> 4NO+6H2O

a.)If 2.90 mol of ammonia and 3.75 mol oxygen are available, how many mol of water are formed?

b.) Which reactant is limiting if 4.20 E4 g of ammonia and 1.31 E5 g of oxygen are available?

c.) What mass of NO is formed in the reaction of 869kg of ammonia and 2480kg of oxygen?

• ### Limiting Reactants help!?

Aluminum chips are sometimes added to sodium hydroxide based drain cleaners because they react to generate hydrogen gas which bubbles and helps loosen material in the drain. The equation follows:

___ Al (s) + ____NaOH (aq) + ____ H2O (l) → ____ NaAlO2 (aq) + ____H2 (g)

a. How many moles of H2 can be generated from 0.57 mol Al and 0.37 mol NaOH in excess water?

b. Which reactant should be limiting in order for the mixture to be most effective as a drain cleaner?

• ### Limiting Reactants help!?

Use the following equation for the oxidation of aluminum in the following problems:

4Al+3O2-->2Al2O3

a.) How many moles of Al2O3 are formed from the reaction of 6.38 E-3 mol of O2 and 9.15 E-3 mol Al?

b.) If 3.17g Al and 2.55g of O2 are available, which reactant is limiting?

• ### Stoichiometry Help!!!!!!?

The following reaction shows the synthesis of zinc citrate, and ingredient in toothpaste: 3ZnCO3+2C6H8O7-->Zn3(C6H5O7)2+3H2O+3CO2

What quantities in kilograms of water and carbon dioxide are produced from 500. mol of C6H8O7?

I know the answer, but i need to know the work behind it.

• ### Stoichiometry Help!!!!!?

Ammonium hydrogen phosphate, (NH4)2HPO4 is made form reacting phosphoric acid with ammonia.

What mass of ammonia will react with 2800 kg of phosphoric acid?

I know the answer, I need to know the work involved.

• ### How many grams of Hydrogen are needed to react with 1.40g of Nitrogen to produce ammonia?

Stoichiometry Worksheet help!

• ### What kind of reaction is 2 C12H26 + 37 O2 = 24 CO2 + 26 H2O?

The answer i'm looking for should be one of these: decomposition, single replacement, double replacement, hydrocarbon combustion, etc.

• ### What kind of a reaction is 2 BN + 3 F2 = 2 BF3 + N2?

The answer i'm looking for should be one of these: decomposition, single replacement, double replacement, hydrocarbon combustion, etc.
