If every oxygen is combined with an aluminium ion, it has a charge of -2, The charge of each aluminum ion would be -3.
Uncharged Aluminum atom must need to lose it's electrons,in order to form the bond with oxygen which has vacant orbitals
ion
atom that has a positive or negative charge because it lost or gained one or more electrons
chemical bond
the attractive force that holds atoms or ions together
ionic bond
a chemical bond in which one atom loses an electron and the other atom gains electrons to form ions
chemical formula
a combination of chemical symbols and numbers to represent a substance
Thanks
covalent bond
bond formed by the sharing of electrons between atoms
Answer:
0.429 J/g.°C
Explanation:
Step 1: Calculate the heat absorbed by the water (Qw)
We will use the following expression.
Q = c × m × ΔT
where,
c: specific heat capacity
m: mass
ΔT: change in the temperature
Qw = 4.184 J/g.°C × 150. g × (29.8°C-25.0°C) = 3012 J
Step 2: Calculate the heat released by the sample of nickel
According to the law of conservation of energy, the sum of the heat lost by the sample of nickel and the heat absorbed by the water is zero.
Qw + QNi = 0
QNi = -Qw = -3012 J
Step 3: Calculate the specific heat capacity of nickel
We will use the following expression.
QNi = c × m × ΔT
c = QNi/m × ΔT
c = -3012 J/100.0 g × (29.8°C-100.0°C) = 0.429 J/g.°C
