Answer:
0.4589J/g°C
Explanation:
Heat energy = 1050J
Mass of iron = 220.0g
Initial temperature (T1) = 10°C
Final temperature (T2) = 20.4°C
Heat energy = mc∇T
Q = mc∇T
Q = heat energy
M = mass of the substance
C = specific heat capacity of the substance
∇T = change in temperature = T2 - T1
Q = m×c×(T2 - T1)
1050 = 220 × c ×(20.4 - 10)
1050 = 220c × (10.4)
1050 = 2288c
c = 1050 / 2288
C = 0.4589J/g°C
The specific heat capacity of iron is 0.4589J/g°C
We have that the Electronegative difference of 2.15 basically makes ionic bonds
Ionic bonds is to be formed
<h3>Bonding</h3>
Generally, the common electronegativity of the team 1 <u>factors </u>are 0.84 and the common <em>electronegativity </em>of the team 17 factors are 2.99.
Group 17 factors are an awful lot greater electronegative than Group 1 elements.
Group 17 consists of F, Cl, Br and I,Group 1 factor that is Na loses 1 electron from its outermost orbit and varieties Na+ cation.
Group 17 Element that is Cl accepts 1 electron in its outermost orbit and Creates Cl- anion. Now, Na+ cation and Cl- anion combines collectively by using ionic bonds.
Hence, the electronegative difference
(2.99-0.84)=2.15
Electronegative difference of 2.15 basically makes ionic bonds

Answer:
2.275x10⁶g of CN⁻¹ were dissolved in the sample
Explanation:
Molarity is defined as the ratio between moles of solute and liters of solution.
If a CN⁻¹ solution has a concentration of 25mM, there are 0.025 moles of CN⁻¹ per liter of solution.
If the sample has a colume of 3.5x10⁶L, moles of CN⁻¹ are:
3.5x10⁶L × (0.025moles / L) = <em>8.75x10⁴ moles of CN⁻¹ in the sample of water.</em>
In grams (As molar mass of CN⁻¹ is 26g/mol):
8.75x10⁴ moles CN⁻¹ × (26g / mol) = <em>2.275x10⁶g of CN⁻¹ were dissolved in the sample</em>
