Answer:
she should not have multiplied the sulfur atoms by the subscript 4
Explanation:
Answer:
I think this would be iron
Explanation:
Nickel contains more atoms.
<u>Explanation:</u>
Number of atoms is determined by the Avogadro number.
1 mole of substance contains 6.022 X 10²³ atoms.
Given:
Mass of Nickel, Ni = 3.89g
Molecular weight of Ni = 58.6934g
Number of moles of Ni = 3.89/58.6934g
Number of atoms of Ni = 
Number of atoms of Ni = 0.39 X 10²³
Mass of silver, Ag = 6.61g
Molecular weight of Ag = 107.8682g
Number of moles of Ag = 6.61/107.8682
Number of atoms of Ag = 
Number of atoms of Ag = 0.36 X 10²³
Therefore, Nickel contains for atoms.
The equation that is represented by the model is = x²-2x-3=(x − 3)(x + 1).
<h3>What are polynomials?</h3>
Polynomials are defined as the mathematical expression that is made up of variables.and coefficients.
The model is +X-x-x- ,
Which is X -2x ( negative minus negative is plus)
Therefore, the equation that is represented by the model is = x²-2x-3=(x − 3)(x + 1)
