1045
Answer: 1045 J of energy was released on cooling the down the water from 20 °C to 10 °C.
<span>The superscripts in an electron configuration represents the number of electrons and protons in an element. </span>
In order to determine the number of protons in 20.02 mol of Ne, we use Avogadro's number to convert the number of moles to number of atoms, 1 mol = 6.022 x 10^23 atoms. From there, we must know the number of protons in a Neon atom, which is 10. Thus, the formula will be:
(20.02 mol Ne)x(6.022 x 10^23 atoms/mol)x(10 protons/1 atom Ne) =
1.2056 x 10^26 protons
Answer:
<h3>The answer is option A</h3>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
<h3>Force = mass × acceleration</h3>
From the question
mass = 2 kg
acceleration = 3 m/s²
We have
Force = 2 × 3
We have the final answer as
<h3>6.0 N</h3>
