Answer:

Z=26, A = 56, charge +3.

Explanation:

The atomic number is represented by Z. Is equal to the total number of protons that the atom has.  Z=26.

The atomic mass is represented by A. The number results from the total sum of protons and neutrons of an atom.  Both particles have a weight of 1 uma, are in the nucleus and give the mass to the atom.

Mass number (A) = atomic number (Z) + number of neutrons (N)

                        A = 26 + 30

                        A = 56

The net charge of the atom can be calculated by subtracting the negative charges from the positive ones. The positive charges come from the protons and the negative ones from the electrons.

26-23=3

This iron ion has a positive charge +3.

The atomic number of iron ion is \boxed{26} .

The atomic mass of an iron ion is \boxed{56} .

The net charge on an iron ion is \boxed{ + 3} .

Further Explanation:

The <em>smallest particle</em> that is the<em> building block of matter</em> is known as an <em>atom</em>. Most of the space in an atom is empty, and its <em>mass</em> is concentrated inside a small region called the <em>nucleus.</em>

An atom is written as _{\text{Z}}^{\text{A}}{\text{X}} , where A is the mass number, Z is the atomic number and X is the letter symbol of the element.

Protons, electrons, and neutrons are the three subatomic particles that are present in the atom. The Protons and neutrons present in an atom are collectively called nucleons because these are located in the nucleus of the atom. Electrons revolve around the nucleus in definite orbits.

The positively charged subatomic particle is called proton. It is equal to the atomic number (Z) of the element.

Electron is the negatively charged subatomic particle. The number of electrons present in an atom is equal to the number of protons of an atom in a neutral atom.

The subatomic particle with no charge is called neutron. It is situated within the nucleus. The number of neutrons present in the nucleus of an atom is called the neutron number. Atomic mass or mass number is the total number of nucleons within the atomic nucleus. So if the atomic number or the proton number is known, the number of neutrons can be calculated by the difference of mass number (A) and atomic number (Z).

The ion of iron has 26 protons. As the number of protons is same as to the atomic number of the element. So the atomic number (Z) of iron is 26.

The expression to calculate the atomic mass of the element is,

{\text{Atomic mass}}\left({\text{A}}\right)={\text{Number of protons}}+{\text{Number of neutrons}}                                                                                               ......(1)

The number of protons in iron ion is 26.

The number of neutrons in iron ion is 30.

Substitute these values in equation (1) to calculate the atomic mass of iron.

\begin{aligned}{\text{Atomic mass of iron}}&={\text{26}}+{\text{30}}\\&={\mathbf{56}}\\\end{aligned}

The formula to calculate the net charge on the ion is,

{\text{Net charge}}={\text{Number of protons}}-{\text{Number of electrons}}                                                        ......(2)

The number of protons in iron ion is 26.

The number of electrons in iron ion is 23.

Substitute these values in equation (2) to calculate the net charge on the iron ion.

\begin{aligned}{\text{Net charge on iron ion}}&=26 - 23\\&={\mathbf{ + 3}}\\\end{aligned}

So the atomic number, atomic mass and net charge on iron ion are 26, 56, and +3 respectively.

13. What is the symbol for Enthalpy change?
OverLord2011 [107]

Answer:

Explanation:

13 ) symbol of enthalpy change = Δ H .

14 ) enthalpy change is nothing but heat absorbed or evolved .

During fusion enthalpy change

Δ H .= m Lf , m is mass and Ls is latent heat of fusion

During evaporation, enthalpy change

Δ H .= m Lv , m is mass and Lv is latent heat of evaporation

during temperature rise , enthalpy  change

Δ H = m c Δ T

In case of gas , enthalpy change can be calculated by the following relation

Δ H = Δ E + W , Δ E is change in internal energy , W is work done by gas.

15 ) When enthalpy change is negative , that means heat is released to the environment .So reaction is called exothermic .

when heat is absorbed enthalpy change is positive . Reaction is endothermic.

Balance each skeleton reaction, use Appendix D to calculate E°cell , and state whether the reaction is spontaneous:(a) Cu⁺(aq) +
melamori03 [73]

The balanced equation reaction :

2Cu+(aq) + PbO2(s) + SO42–(aq) + 4H+  -----------> PbSO4(s) + 2 Cu2+(aq)  + 2H2O

A balanced equation is an equation for a chemical reaction in which the range of atoms for every detail in the reaction and the full charge is identical for both the reactants and the products. In other phrases, the mass and the fee are balanced in each aspect of the reaction.

A balanced equation happens while the variety of the atoms involved inside the reactants side is identical to the variety of atoms in the goods facet. in this chemical reaction, nitrogen (N2) reacts with hydrogen (H) to provide ammonia (NH3). The reactants are nitrogen and hydrogen, and the product is ammonia.

A chemical equation is the symbolic representation of a chemical reaction inside the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities.

Eo  = Eored - Eo oxd

 = 1.69  - 0.153

 = 1.54 V

Eocell is positive so the reaction is spontaneous.

In a 0.730 M solution, a weak acid is 12.5% dissociated. Calculate Ka of the acid.
Mamont248 [21]

Answer:

Approximately 1.30 \times 10^{-2}, assuming that this acid is monoprotic.

Explanation:

Assume that this acid is monoprotic. Let \rm HA denote this acid.

\rm HA \rightleftharpoons H^{+} + A^{-}.

Initial concentration of \rm HA without any dissociation:

[{\rm HA}] = 0.730\; \rm mol \cdot L^{-1}.

After 12.5\% of that was dissociated, the concentration of both \rm H^{+} and \rm A^{-} (conjugate base of this acid) would become:

12.5\% \times 0.730\; \rm mol \cdot L^{-1} = 0.09125\; \rm mol \cdot L^{-1}.

Concentration of \rm HA in the solution after dissociation:

(1 - 12.5\%) \times 0.730\; \rm mol \cdot L^{-1} = 0.63875\; \rm mol\cdot L^{-1}.

Let [{\rm HA}], [{\rm H}^{+}], and [{\rm A}^{-}] denote the concentration (in \rm mol \cdot L^{-1} or \rm M) of the corresponding species at equilibrium. Calculate the acid dissociation constant K_{\rm a} for \rm HA, under the assumption that this acid is monoprotic:

\begin{aligned}K_{\rm a} &= \frac{[{\rm H}^{+}] \cdot [{\rm A}^{-}]}{[{\rm HA}]} \\ &= \frac{(0.09125\; \rm mol \cdot L^{-1}) \times (0.09125\; \rm mol \cdot L^{-1})}{0.63875\; \rm mol \cdot L^{-1}}\\[0.5em]&\approx 1.30 \times 10^{-2} \end{aligned}.
