Catalysts are chemicals that speed up reactions without changing themselves at the conclusion of the process.

By reducing the reaction's activation energy, they accelerate the pace of the reaction. By offering a surface or an orientation, catalysts reduce the activation energy of a process. supplying a different mechanism (a set of procedures the reaction must follow) with lower activation energy. As a result, catalysts facilitate the formation of chemical bonds between atoms to create novel combinations and new compounds.

If 10.0g of Al2(SO3) is reacted with 10.0g of NaOH, determine the limiting reagent
ehidna [41]

(10.0 g Al2(SO3)3) / (294.1544 g Al2(SO3)3/mol) = 0.033996 mol Al2(SO3)3 (10.0 g NaOH) / (39.99715 g NaOH/mol) = 0.25002 mol NaOH 
0.033996 mole of Al2(SO3)3 would react completely with 0.033996 x (6/1) = 0.203976 mole of NaOH, but there is more NaOH present than that, so NaOH is in excess and Al2(SO3)3 is the limiting reactant.

You have 16.0 g of some compound and you perform an experiment to remove all of the oxygen, 11.2 g of iron is left. What is the
oksian1 [2.3K]

The empirical formula of this compound is equal to Fe_{2}O_3.

<h3>Empirical formula</h3>

To calculate the empirical formula of a compound, it is necessary to know the number of moles present.

Therefore, we will use the molar mass of iron and oxygen to find the amount of moles, so that:

MM_O = 16g/mol\\MM_Fe = 55.8g/mol

                                        MM = \frac{m}{mol}

  • Oxygen

                                            16 = \frac{4.8}{mol}

                                            mol = 0.3

  • Iron

                                   

                                               55.8 = \frac{11.2}{mol}

                                               mol = 0.2

Finally, as the empirical formula is composed of integers numbers of moles, just multiply the values ​​by the smallest common factor to transform into an integer, so that:

                                       O =>  0.3 \times 10 = 3moles

                                       Fe => 0.2 \times 10 = 2moles

So, the empirical formula of this compound is equal to Fe_{2}O_3

A ballon begins at sea level at 1 atm. It rises in the atmosphere to where the pressure is lower, to where the pressure is .75 a
maxonik [38]

Answer:

Original volume=3L

Explanation:

Assuming the gas in the ballon is ideal and the temperature does not vary with height  we have the gas law as

PV=nRT

Here RHS is constant in both the conditions which means

PV=constant

Given P1=1 atm V1=V  P2=0.75atm V2=4L

P1V1=P2V2

1*V=0.75*4

V=3L

The initial volume of the gas is 3L
