Answer: 323.61 g of will be produced
Explanation:
The given balanced chemical reaction is :
According to stoichiometry :
2 moles of require 1 mole of
Thus 3.00 moles of will require= of
Thus is the limiting reagent as it limits the formation of product.
As 2 moles of give = 2 moles of
Thus 3.00 moles of give = of
Mass of
Thus 323.61 g of will be produced from the given moles of both reactants.
Answer:
Endothermic
Explanation:
Because Endothermic is cold and exothermic is hot and if you are using an ice pack it would be Endothermic and if you were using something that was hot it would be exothermic
By international agreement, absolute zero is defined as precisely; 0 K on the Kelvin scale, which is a thermodynamic (absolute) temperature scale; and –273.15 degrees Celsius on the Celsius scale.
