Endothermic reactions, on the other hand, absorb heat and/or light from their surroundings. For example, decomposition reactions are usually endothermic. In endothermic reactions, the products have more enthalpy than the reactants. Thus, an endothermic reaction is said to have a positive<span> enthalpy of reaction. This means that the energy required to break the bonds in the reactants is more than the energy released when new bonds form in the products; in other words, the reaction requires energy to proceed</span>
Liquids flow because its particles can move over each other. The particles have freedom to move and they will keep moving until it takes the shape of its container.
Solid particles are rigid and tightly packed, they cannot move, so it does not flow.
The specialized type of cell in human eyes which help to detect color, a layer at the back of the eyeball containing cells that are sensitive to light and that trigger nerve impulses that pass via the optic nerve to the brain, that is called a retina.
at 60ºC:
106 g KNO₃ -------------- 100 g (H₂O)
? g KNO₃ ------------------ 50.0 g (H₂O)
mass KNO₃ = 50.0 * 106 / 100
mass KNO₃ = 5300 / 100
<span>= </span>53 g of KNO₃
answer (2)
<span>hope this helps!</span>
Answer:
Option C (a higher; the same) is the appropriate response.
Explanation:
Given:
Temperature,
T = 300 K (both 
and 
)
As we know,
Average speed of a molecule,
⇒ 
Thus, the average speed of will be lower as its molar mass is greater than .
Now,
⇒ 
(not depend on molar mass)
Hence, it will be the same.
The other three alternatives aren't connected to the scenario given. So the above is the correct answer.
