Answer:
Positive
Explanation:
In an endothermic reaction, the products are at a higher energy than the reactants. This means that the enthalpy change of the reaction (∆H) is positive
The average distance from the Sun to Neptune is about 2.795 billion miles.
That's roughly 0.00048 of a light year .
Answer:
The velocity when the ball hits the ground is obtained using v2. 2 = v1. 2 + 2 g Dy with v1=0 and Dy=h. Thus solving for v2 yields 17.1 m/s v2 = 2 g h =.

<h3>Option D) The red liquid has a smaller specific heat</h3>
When a substance has smaller specific heat it needs less heat to shows changes in it hence making the option D correct.
