what the difference between a sodium atom (Na) and a sodium ion (Nal+)
Answer:
So a sodium atom has the electronic configuration 2,8,1 meaning it has 1 electron on its outer shell. It has a neutral charge since the number of electrons is equal to the number of protons.
A sodium ion is one that has lost the electron on its valence shell. The electronic configuration is 2,8 and it has a positive charge because it has more protons than electrons.
Answer:
[tex]\boxed {\boxed {\sf Number \ of \ electrons \ and \ net \ charge}}[/tex]
Explanation:
Remember that protons have a positive charge of +1 and electrons have a negative charge of -1. Atoms have protons and electrons.
A sodium atom has the electron configuration of 2-8-1. It has 11 electrons and its atomic number (number of protons) is also 11. This means it is a neutral atom because the charges of the electrons (-11) and protons (+11) balance each other out.
However, a sodium ion is different. It loses the 1 valence electron, so it only has 10 electrons. It still has the same atomic number of 11.
It is a not a neutral atom because the charges of the electrons (-10) and protons (+11) do not balance out. It has more protons and a net positive charge of +1. It is a cation or a positively charged ion.

How many moles of potassium Chlorate are needed to produce 15.0 moles of oxygen
Answer:
10 moles of potassium Chlorate are required to produce 15 mole of oxygen
Explanation:
The balanced chemical equation is
2KClO3(s)→2KCl(s)+3O2(g)
2 moles of potassium Chlorate produce 3 moles of oxygen
Number of moles of potassium Chlorate required to produce 1 mole of oxygen [tex]= \frac{2}{3}[/tex]
Number of moles of potassium Chlorate required to produce 15 mole of oxygen
[tex]= \frac{2}{3} * 15\\= 10[/tex]
10 moles of potassium Chlorate are required to produce 15 mole of oxygen

Calculate the specific heat of an unknown metal if it took 58.1 J to increase the temperature of 89.4 g of the metal from 23.4°C to 25.5°C.
Answer:
[tex]c=0.309\ J/g^{\circ} C[/tex]
Explanation:
The increase in heat, Q = 58.1 J
Mass, m = 89.4 g
The temperature increases from 23.4°C to 25.5°C. We need to find the specific heat of an unknown metal.
We know that the increase in heat is given by :
[tex]Q=mc\Delta T\\\\c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{58.1}{89.4\times (25.5-23.4)}\\\\c=0.309\ J/g^{\circ} C[/tex]
So, the specific heat of an unknown metal is equal to [tex]0.309\ J/g^{\circ} C[/tex].
A boulder sits at rest on top of a mountain. What conclusion can be made about the forces acting on the boulder
Explanation:
Since, the boulder is at rest. This means that there is an equilibrium of forces acting on the boulder.
According to principle of equilibrium of forces a body can be in position of rest only when net force acting on body is zero for translation equilibrium and net moment acting on the body must also be zero for rotational equilibrium.
Therefore, net forces and net moment acting on the boulder is zero.

The equilibrium constant kc of the reaction H2+I2 produces HI is 54.3at430°C. Starting with 6.0moles,of HI moles of HI in 1.0dm^3 reaction vessel, calculate th5 concentration of H2,I2 and HI at equilibrium
Answer:
[H2] = [I2] = 0.64M; [HI] = 4.72M
Explanation:
Based on the reaction:
H2 + I2 ⇄ 2HI
The K is defined as:
k = 54.3 = [HI]² / [H2] [I2]
Where [] is molar concentration of each reactant at equilibrium
As the initial concentration of HI is 6mol/dm^3 = 6M the equilibrium concentration of each reactant is:
[H2] = X
[I2] = X
[HI] = 6 - 2X
Where X is reaction coordinate
Replacing:
54.3 = [6-2X]² / [X] [X]
54.3X² = 4X² - 24X + 36
0 = -50.3X² - 24X + 36
Solving for X:
X = -1.12. False solution, produce negative concentrations
X = 0.64M. Right solution
Replacing:
[H2] = 0.64M
[I2] = 0.64M
[HI] = 6 - 2*0.64M = 4.72M
Equilibrium concentrations are:
[H2] = [I2] = 0.64M; [HI] = 4.72Mhelp me please id appreciate it

What are the half-reactions for a galvanic cell with aluminum and gold electrodes?
A. A3+ (aq) + 3e > Al(s) and Au+(aq) + e* → Au(s)
B. Al(s) → A13+(aq) + 3e and Aut(aq) + e
Au(s)
C. AB+(aq) + 3e – Al(s) and Au(s) — Au (aq) + e
D. Al(s) → AB+(aq) + 3e and Au(s) → Au(aq) + e
Answer:B is right
Explanation: Al loses electrons and is oxidised, Au gains electron. And is reduced
To solve such this we must know the concept of half cell reaction. Therefore, the correct option is option B that is Al(s) → A1³⁺(aq) + 3e and Au(aq) + e [tex]\rightarrow[/tex]Au(s)
What is chemical reaction?Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
Oxidation is loss of electrons and reduction is gain of electrons. The electron transfer from oxidant to reductant. Al loses electrons and is oxidized, Au gains electron. And is reduced.
Therefore, the correct option is option B that is Al(s) → A1³⁺(aq) + 3e and Au(aq) + e [tex]\rightarrow[/tex]Au(s)

At the same temperature and pressure, 15L of CO2 gas has the same amount of molecules as what volume of N2 gas?
Answer: 15 L of [tex]N_2[/tex] gas will have same numer of molecules as 15L of [tex]CO_2[/tex] gas at the same temperature and pressure,
Explanation:
According to avogadro's law, equal moles of gases occupy equal volume at same conditions of temperature and pressure.
[tex]\text{Number of moles}=\frac{\text{Given volume}}{\text{Molar volume}}[/tex]
[tex]\text{Number of moles of} CO_2=\frac{15L}{22.4L/mol}=0.67mol[/tex]
[tex]1 mole of CO_2[/tex] contains=[tex]6.022\times 10^{23}[/tex] molecules of [tex]CO_2[/tex]
Thus 0.67 moles of [tex]CO_2[/tex] contains=[tex]\frac{6.022\times 10^{23}}{1}\times 0.67=4.03\times 10^{23}[/tex] molecules
Now molecules of [tex]N_2[/tex] = molecules of [tex]CO_2[/tex] = [tex]4.03\times 10^{23}[/tex]
[tex]6.023\times 10^{23}[/tex] molecules of [tex]N_2[/tex] = 22.4 L
Now [tex]4.03\times 10^{23}[/tex] molecules of [tex]N_2[/tex] = [tex]\frac{22.4}{6.023\times 10^{23}}\times 4.03\times 10^{23}=15L[/tex]

Consider the reaction
2 NO2 (g) <=> N2O4
If the equilibrium concentration of both NO2 and N2O4 are 0.2 M, what is the value of Kc?
A. 0.2
B. 0.3
C. 0.225
D. 5.0
E. 2.5
Please help.
Answer:
D. 5.0
Explanation:
Step 1: Write the balanced equation at equilibrium
2 NO₂(g) ⇄ N₂O₄(g)
Step 2: Calculate the concentration equilibrium constant
The concentration equilibrium constant (Kc) is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients.
Kc = [N₂O₄]/[NO₂]² = 0.2 / 0.2² = 5
