The following data was collected when a reaction was performed experimentally in the laboratory.
Reptile [31]

The maximum amount of AlCl_3 produced during the experiment can be find out by knowing the Limiting Reagent.

Here, The maximum amount of AlCl_3 produced during the experiment is  400 grams

<h3>What is Limiting reagent ?</h3>

The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is stopped.

Now, According to the question,

Given ;

Number of moles of Al(NO_3)_3 - 4 moles

Number of moles of NaCl - 9 moles

To Find - Maximum amount of AlCl_3 produced during the reaction.

Solution ;

complete reaction ;

Al(NO_3)_3  + 3NaCl -->   3NaNO_3 + AlCl_3

To find the maximum amount of AlCl_3 produced during the reaction,

we need to find the limiting reagent.

Mole ratio Al(NO_3)_3  = 4/1 = 4

Mole ratio NaCl = 9/3 = 3

Thus, NaCl is the limiting reagent in the reaction.

Now, 3 moles of NaCl produces 1 mole of   Al(NO_3)_3

9 moles of NaCl will produce = 1/3 x 9 = 3 moles.

Weight of   Al(NO_3)_3 = 3 x 133.34 = 400 grams

Thus, 400 grams of   Al(NO_3)_3  is the maximum amount of   Al(NO_3)_3 produced during the experiment.

Neutrons were discovered in 1932, more than 10 years after the existence of isotopes was confirmed. What property of electrons a
kirza4 [7]

Protons and neutrons are the sub-atomic particles present in the nucleus of an atom where as electrons are present revolving round the nucleus in orbits. Electrons are negatively charged, protons are positively charged where as a neutron is a neutral species. It is the presence of electric charge that lead to the discovery of electrons (negative charge) and protons (positive charge), while it took time to discover neutral as they were electrically neutral species. Neutrons carrying no charge were not detected easily by passing electromagnetic radiations. Therefore, neutrons were the last of the three subatomic particles, to be discovered.

If you were presented with 2l of a 2m sucrose stock solution, how many grams of sugar would be in a 100 ml aliquot?
Rashid [163]

The 2 L of sucrose stock solution would contain similar concentration with the 100 mL aliquot. Therefore the concentration of aliquot is still 2 M.

The molar mass of sucrose is 342.3 g / mol. Therefore the mass in a 100 mL (0.1 L) aliquot is:

mass = (2 mol / L) * 0.1 L * (342.3 g / mol)

<span>mass = 68.46 g</span>

Two glasses of water have the same thermal energy. Must they have the same temperature? Explain
ira [324]
Even if two samples of matter have the same temperature, it does not necessarily mean they have the same total energy. The more particles a substance has at a given temperature, the more thermal energy it has.
