Answer:
24.87× 10²³ atoms of Ni
Explanation:
Given data:
Number of atoms of Ni= ?
Number of moles of Ni = 4.13 mol
Solution:
we will calculate the number of atoms of Ni by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
4.13 mol × 6.022 × 10²³ atoms /1 mol
24.87× 10²³ atoms of Ni
Answer:
I know that the electrons flow would be: The electrons will flow from lithium to zinc.
Explanation:
But I also dont know what would make this an even stronger battery.
A solution is a mixture of two or more substances combined so that it is uniform, which means you cannot see the components. <span />
Answer:
45 minutes about
Explanation:
i think because i have 7 periods with 45 minutes each
Because zinc is above lead on the activity series. This means that in a single displacement reaction such as this one, Pb will not easily displace Zn.
