Answer:
number of atoms = 3.04111 * 10^24 atoms
Explanation:
One mole of any substance contains Avogadro's number of atoms.
Therefore, to know the number of atoms in "x" moles, all you have to do is multiply the number of moles (x) by Avogadro's number.
In the question, we are given that the number of moles is 5.05 moles
Therefore:
number of atoms = 5.05 * 6.022 * 10^23 = 3.04111 * 10^24 atoms
Hope this helps :)
An atom becomes positively charged by loosing electrons.
Answer:
= 1375 joules
Explanation:
- Kinetic energy refers to the energy possessed by an object or a body when in motion.
- It is calculated by halving the product of the mass of the body and the square of its velocity.
That is;
Kinetic energy = 0.5 × Mass × velocity²
Therefore, in this case;
Kinetic energy of linebacker = 0.5 × 110 Kg × 5²
= 1375 Joules
Therefore; the kinetic energy of the line backer is 1375 joules
Answer:
A body becomes weightless in a zero-gravity scenario and when a force is applied to a body that is equal and opposite to the force of gravity. If the body is falling only under the influence of gravity.
It is Titration (when you adding ,for example, acid to base)
