Describe the difference between a reaction that occurs spontaneously and one that does not

1 answer:

4 0

2.B. Describe the difference between a reaction that occurs spontaneously and one that does not. Spontaneous chemical reactions release energy and use that energy to power itself; non-spontaneous chemical reactions need to absorb energy, which they can't absorb their own energy that they don't even have.

So you need to put numbers before each compound to make sure there are the exact same number of elements on each side. If you put a 4 before NH4 there are 4 Nitrogen and now 16 hydrogen. I just played around with numbers and guessed until I got them even.

The speed of the yacht : 100 km/h

<h3>Further explanation </h3>

Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration

At constant velocity motion:

the speed of vo = v = constant

acceleration = a = 0

Δx = vt or x = xo + vt

An equation of constant velocity motion

$\large {\boxed {\bold {x = v \times \: t}}}$

x = distance = m

v = speed = m / s

t = time = seconds

A yacht sailed at a steady speed for 0.5 hours, and traveled 50 kilometers

so the velocity/speed:

$\tt v=\dfrac{x}{t}\\\\v=\dfrac{50~km}{0.5~h}=\boxed{\bold{100~km/h}}$
