Hi,
Answer is 191.2.
800J = 191.2 cal
Hope this helps.
Answer:
Reactant concentration, the physical states of the reactants, surface area, temperature and the presence of catalyst.
Answer: NO2.
You can predict that two atoms with similar electronegativity will form covalent compounds while atoms with pretty different electronegativity will form ionic compounds.
Given that N and O are neighbors on the periodic table, you can predict they have similar electronegativities.
Also you can predict that from the fact that N and O are nonmetals, which also means that they will form covalent compounds.
The other compounds liste are formed by metals and non metals wich is an indication that they will have, at least, some ionic character.
Ergo, N and O will form covalent compounds, in this case NO2.
I think the answer is 0.00000064.
Please tell me if I'm wrong.
Sodium(Na) is the limiting reagent.
<h3>What is Limiting reagent?</h3>
The reactant that is totally consumed during a reaction, or the limiting reagent, decides when the process comes to an end. The precise quantity of reactant required to react with another element may be estimated from the reaction stoichiometry.
How do you identify a limiting reagent?
The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced. Calculate how many moles of each reactant are present and contrast this ratio with the mole ratio of the reactants in the balanced chemical equation to get the limiting reactant.
Start by writing the balanced chemical equation that describes this reaction
Notice that the reaction consumes 2 moles of sodium metal for every 1 mole of chlorine gas that takes part in the reaction and produces 2 moles of sodium chloride.
now we can see that we have 3 moles of sodium and 3 moles of chlorine, according to question. so, we can say that sodium is the limiting reagent in the given situation.
