An ice cube melts in the hot sun. Is this exothermic or endothermic and
why?
Answer:
Endothermic
Explanation:
In order to melt the ice cube, heat is required, so the process is endothermic. Endothermic reaction In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction.
Question in picture!!!!!!
Answer:
6 atoms
Explanation:
predict how many moles of nh3 would be made if 6.00 moles of h2 were used N2
Answer:
4 moles
Explanation:
The equation is 3H2 + N2 → 2NH3
so the ratio of moles would be
2:3 or 2/3
so 6*2/3 which is 4
hope this helped.
Answer:
4moles
Explanation:
Given parameters:
Number of moles of H₂ used = 6moles
Equation of the reaction:
N₂ + 3H₂ → 2NH₃
3 mole of H₂ was used to produce 2 mole of NH₃;
6 mole of H₂ will produce [tex]\frac{6x2}{3}[/tex] = 4 moles of NH₃
The number of moles of NH₃ produced is 4moles
Two moles of acetyl chloride was mixed with two moles of dimethylamine. After the reaction is complete, what species can be found in the mixture
Answer:
See explanation
Explanation:
The reaction is shown in the image attached. This reaction occurs by a carbocation (ionic) mechanism.
The lone pair on the nitrogen atom attacks the carbocation leading to the formation of the product as shown in the image attached.
Since the reaction occurs in a 1:1 ratio, two moles of reactants yields two moles of product.
Whenever the same two elements form more than one
compound, the different masses of one element that combine
with the same mass of the other element are in the ratio of
small whole numbers.
TRUE
FALSE
Answer:
The answer is true
Explanation: Because The law of multiple proportions states that when two elements react to form more than one compound, a fixed mass of one element will react with masses of the other element in a ratio of small, whole numbers.
Which of the following conclusions about the two intermolecular forces is correct? X represents London dispersion forces, and Y represents ion-dipole forces. X represents dipole-dipole forces, and Y represents ion-dipole forces. X represents hydrogen bonding, and Y represents dipole-dipole forces. X represents London dispersion forces, and Y represents dipole-dipole forces.
Answer:
X represents London dispersion forces, and Y represents dipole-dipole forces.
