Calculate the number of atoms in a 1.94 x 10^3 g sample of calcium
34kurt
n =  \frac{m}{M}

n =  \frac{1.94*10^3}{40.08}

n = 48.40 mol

Then,

N = n*Na
N = 48.40*6.02*10^{23}
N= 2.94*10^{25} atoms

Hope this helps !

N the ionic compound aluminum selenide, each atom of aluminum (gains or loses)
Volgvan

Answer:

loses, gains

Explanation:

In the ionic compound aluminum selenide, each atom of aluminum will lose electrons while each atom of selenium will gain the electrons.

An ionic compound is an interatomic bond formed between a metal and non-metal. The metal is less electronegative compared to the non-metal. In this case, the metal will lose electrons to become positively charged whereas the non-metal, selenium will gain the electron to become negatively charged.

The electrostatic attraction between these oppositely charged ions leads to the formation of the ionic bond.
