Answer:
yes 4K + O2 ------>2K20 is true.
Answer:
8.9x10¹⁷ atoms of Al are present
Explanation:
To find the number of atoms from the mass of an atom we must convert, as first, the mass to moles using the molar mass of the atom (26.98g/mol For Aluminium).
Then, we must convert the moles to atoms knowing that 1mol = 6.022x10²³ atoms.
<em>Moles Aluminium:</em>
4.0x10⁻⁵g * (1mol / 26.98g) = 1.483x10⁻⁶ moles Al
<em>atoms:</em>
1.483x10⁻⁶ moles Al * (6.022x10²³ atoms / mol) =
<h3>8.9x10¹⁷ atoms of Al are present</h3>
Answer:
Investigating how experimental conditions can effect the speed of a chemical reaction and give insight into reaction mechanisim and states.
Explanation:
Chemical kinetics is a process of investigation how experimental conditions can affect the speed of a chemical reaction and give insight into reaction mechanism and states.
- Chemical kinetics deals with two aspects chemical reaction; the speed at which reaction occurs(reaction rate) and the details of the steps involved in the reaction(reaction mechanism).
- The two aspects are closely related.
