what is the amount of charge on a calcium ion if its neutral atom has lost two valence electrons?
Answers
A calcium ion will have a positive charge when it loses an electron. If it loses 2 electrons, the calcium ion will have 18 electrons and a 2+ charge.
In order to meet its octet rule on what would eventually become the new valence shell, the calcium atom, which currently has two valence electrons, must lose both of them. Consequently, it has a 2+ charge. Calcium contains 20 protons but only 18 electrons since it lost two electrons. As a result, calcium has a charge of 2+, making it a positive ion. With 20 protons and 20 electrons, a neutral calcium atom easily loses two electrons. A cation with 20 protons, 18 electrons, and a 2+ charge is the consequence of this. It is represented by the formula Ca2+ and has the same number of electrons as atoms of argon, the previous noble gas.

A mixture of He, Ne, and N2 gases has a pressure of 0,898 atm. If the pressures of He and Ne are 0.336 atm and 0.106 atm, respectively, what is the partial pressure of N2 in the mixture?
Answers
Answer:
Pressure for N₂ = 0.456 atm
Explanation:
There is law for gases which states that the sum of partial pressures of each gas in a mixture, is equal to the total pressure of the system.
For this case, we have a mixture of He, Ne and N₂
Then Total pressure is 0.898 atm
He's pressure + Ne's pressure + N₂'s pressure = 0.898 atm
N₂'s pressure = 0.898 atm - 0.336 atm - 0.106 atm
Pressure for N₂ = 0.456 atm
This is called the Dalton's law of partial pressures.

an atom of 135i has a mass of 134.910023 amu. calculate its binding energy per mole in kj. enter your answer in exponential format (1.23e4) with 3 significant figures and no units. use the masses: mass of 1h atom
Answers
Answer:
To calculate the binding energy per mole of 135I, we need to first determine its mass defect (Δm) using the atomic masses of its constituents:
Mass of 135I atom = 134.910023 amu
Mass of 53 protons = 53 x 1.007825 amu = 53.421325 amu
Mass of 82 neutrons = 82 x 1.008665 amu = 82.82893 amu
Total mass of 135I nucleus = 53.421325 amu + 82.82893 amu = 136.250255 amu
Δm = (mass of 135I atom) - (total mass of 135I nucleus)
= 134.910023 amu - 136.250255 amu
= -1.340232 amu
The binding energy (BE) can be calculated from the mass defect using Einstein's famous equation:
BE = Δm x c^2
where c is the speed of light in a vacuum (299,792,458 m/s).
BE = -1.340232 amu x (1.66054 x 10^-27 kg/amu) x (299,792,458 m/s)^2 / (6.02214 x 10^23 atoms/mol) / 1000 J/kJ
= -2.2008 x 10^-11 J/atom
Multiplying by Avogadro's number (6.02214 x 10^23 atoms/mol) gives the binding energy per mole:
BE/mol = -2.2008 x 10^-11 J/atom x (6.02214 x 10^23 atoms/mol) / 1000 J/kJ
= -1.3241 x 10^4 kJ/mol
Rounding to 3 significant figures and expressing in exponential format gives the final answer of -1.32e4 kJ/mol.

Gold, along with Copper, is one of the Coinage Metals that belong to Group 1B. However, Gold will not dissolve in Nitric Acid. It requires Aqua regia to dissolve Gold. What is Aqua regia and why does it dissolve Gold
Answers
Aqua regia is a powerful and versatile solvent capable of dissolving noble metals like gold and platinum, making it an important tool in chemical analysis and metallurgy. However, it must be handled with great care due to its highly corrosive and toxic nature.
Aqua regia is a highly corrosive mixture of concentrated hydrochloric acid (HCl) and concentrated nitric acid. It is so named because it can dissolve "royal" or noble metals like gold and platinum, which are otherwise resistant to most acids.
Aqua regia works by combining with the gold to form soluble gold chloride ions that are easily dissolved in the solution. This reaction occurs due to the oxidizing nature of nitric acid, which oxidizes the gold to form \(AuCl_4^- {ions}\). The chloride ions from hydrochloric acid then form a complex with the gold ions, making them soluble in the solution.
The high reactivity of nitric acid is due to its ability to donate a highly reactive nitronium ion that can oxidize the gold. The resulting nitric oxide gas (NO) released in the process also helps to dissolve the gold.

Sodium chloride is NaCl, and zinc chloride ZnCl₂. Why are there more chloride ions in the zinc compound?
Answers
Answer:
Zinc chloride (ZnCl2) has more chloride ions compared to sodium chloride (NaCl) because the zinc ion has a +2 charge, while the sodium ion has a +1 charge.
Chlorine (Cl) is a halogen element with a -1 charge when it gains an electron to form an ion. To form a neutral compound, the number of positive and negative charges must be balanced.
In NaCl, the sodium ion has a +1 charge and can only bond with one negatively charged chloride ion, which has a -1 charge. Therefore, the formula for sodium chloride is NaCl, with one sodium ion and one chloride ion.
In ZnCl2, the zinc ion has a +2 charge, and it requires two negatively charged chloride ions, each with a -1 charge, to form a neutral compound. Therefore, the formula for zinc chloride is ZnCl2, with one zinc ion and two chloride ions.
Thus, the reason why there are more chloride ions in the zinc compound is because the zinc ion has a higher charge compared to the sodium ion, and it requires two chloride ions to balance its charge, whereas sodium ion requires only one chloride ion.

If 2 moles of Fe2O3 react with 9 moles of CO, how many moles of each product are formed?
Answers
When 2 mole of Fe2O3 and 9 molecules of CO react, 6 moles of the each product are created.
Describe a mole.The term "mole" refers to a common scientific measurement unit for atoms, molecules, and other very small particles.
The first one is supposed to produce a balanced chemical reaction in accordance with the situation supplied.
FeO3 + 3 CO 2 Fe + 3CO2 is the formula.
Because 2 moles of Fe2O3 reacted with 3 x2=6 moles of Co to produce Fe and CO2, CO was in excess and Fe2O3 was the limiting reagent.
Utilize the mole ratio to determine the moles of the each product.
That is the Fe2O3 mole ratio: Because Fe is a 1:2 element, the mole of Fe is 2x2=4 moles.
Because the mole ratio of Fe2CO3 to CO2 is 1:3, the moles of Co2 are 2 x 3 = 6 moles.
Therefore, 6 moles of the each product will be created when 2 moles or Fe2O3 react to 9 moles of CO.

Answers
The temperature at which a gas occupies a given volume is inversely proportional to the volume, according to the ideal gas law:
PV = nRT
where P is the pressure, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature.
Since the number of moles and the pressure are constant in this problem, we can rewrite the equation according to Charles' Law
V1/T1 = V2/T2
Solving for T2, we get:
T2 = (T1 * V2)/V1
Plugging in the values given in the problem, we get:
T2 = (6.50*145)/1.45
T2 = 650 K

What is the concentration (M) of sodium ions in 4.57 L of a
0.268 mol L-1 Na3P solution?
Answers
The concentration (M) of sodium ions in a 0.268 mol/L Na3P solution can be calculated by considering the stoichiometry of the compound. The concentration of sodium ions in the 4.57 L Na3P solution is 0.268 M
In this case, the concentration of Na3P is 0.268 mol/L, and the volume of the solution is given as 4.57 L. Multiplying these values together gives us the number of moles of Na3P in the solution, which is 1.225 mol. Since there are three sodium ions per molecule of Na3P, the number of moles of sodium ions is also 1.225 mol.
To find the concentration of sodium ions, we divide the number of moles of sodium ions by the volume of the solution. Therefore, the concentration of sodium ions in the 4.57 L solution is 1.225 mol / 4.57 L = 0.268 M.
In summary, the concentration of sodium ions in the 4.57 L Na3P solution is 0.268 M, obtained by considering the stoichiometry of Na3P and dividing the number of moles of sodium ions by the volume of the solution.
