A metal ion (X) with a charge of 2+ is attracted to a nonmetal ion (Z) with a charge of 3-.Which formula represents the resultin
Viefleur [7K]

Answer:

X₃Z₂

Explanation:

A metal ion (X) with a charge of 2+  =  X²⁺

nonmetal ion (Z) with a charge of 3-   = Z³⁻

In a neutral compound, the charges but balance each other to remain neutral. However in this case, the charges are not balanced.

A simple way to make the charges balance is by tweaking the number of the ions present in the compound.

We do this by multiplying the metal ion with 3 and the non metal ion by 2.

That way we have;

Metal ion = 3X2⁺   (Total charge - 6⁺)

Non metal ion = 2Z3⁻  (Total charge -  6⁻)

The charges are now balanced. The formular of the compound is;

X₃Z₂

If 832J of energy is required to raise the temperature of a sample of aluminum from 20.0° C to 97.0° C, what mass is the sample
LiRa [457]
Data:
Q (Amount of heat) = 832 J
m (mass) = ?
c (Specific heat) = <span>0.90 J/(g × ° C)
T (final) = 97 ºC
To (initial) = 20 ºC
</span>ΔT = T - To → ΔT = 97 - 20 → ΔT = 77 ºC

Formula:
Q = m*c*ΔT

Solving:
Q = m*c*ΔT
832 = m*0.90*77
832 = 69.3m
69.3m = 832
m =  \frac{832}{69.3}
\boxed{\boxed{m \approx 12.00\:g}}\end{array}}\qquad\quad\checkmark

Georgia [21]
Q=44.0 ct
p=3.51 g/cm³
Δq=0.200 g/ct

m=q×Δq

v=m/p=q×Δq/p

v=44.0×0.200/3.51≈2.5 cm³


C.  2.5 cm³
