Calculate the mass of iron(III) oxide (Fe₂O3) that contains a billion (1.0 × 10^9) oxygen atoms.
Be sure your answer has a unit symbol if necessary, and round it to 2 significant digits.
Answers
The balanced chemical equation for rusting iron is:
4Fe + 3O2 = 2Fe2O3
If we divide 1.0x10^9 by Avogadro's number, we get the amount of moles of oxygen which is 1.6611x10^-15 moles.
From the chemical equation we know that it takes 3 moles of oxygen to produce 2 moles of iron oxide. So if we multiply the moles of oxygen calculated by 2/3, we can get the moles of iron oxide.
(1.611x10^-15)(2/3) = 1.107419x10^-15 moles of iron oxide.
If we multiply the moles of iron oxide by the molar mass of iron oxide, we get how many grams of iron oxide would be produced by 1 billion oxygen atoms. Which is the same thing as how many grams of iron oxide contain 1 billion oxygen atoms.
(1.107419x10^-15)(159.69) = 1.8x10^-13 grams of Fe2O3

for a molecule to be studied in IR spectra?
Answers
The molecule must possess dipolar bonds, exhibit suitable vibrational frequencies, and be in a form that can be analyzed using IR spectroscopy in order to be studied in an IR spectrum.
To study a molecule in an infrared (IR) spectrum, several criteria need to be considered. Firstly, the molecule should have a dipole moment, meaning it must have a separation of positive and negative charges within the molecule.
This is because IR spectroscopy primarily detects vibrations of covalent bonds, which are associated with changes in dipole moment.Additionally, the molecule should have covalent bonds that can undergo vibrational modes within the range of the instrument. IR spectroscopy typically covers the frequency range of 4000 to 400 cm⁻¹, which corresponds to the energies of molecular vibrations.
The molecule should also be able to be vaporized or dissolved in a suitable solvent to generate a homogeneous sample for analysis. Gaseous or liquid samples are commonly used in IR spectroscopy.

Gallium has two naturally occurring isotopes: Ga-69 with a mass of 68.9256 amu and a natural abundance of 60.11 % and Ga-71 . Use the atomic mass of gallium from the periodic table to find the mass of Ga-71 .
Answers
The atomic mass of an element can be determined from its isotopic masses. The mass of the isotope of gallium Ga-71 is 71.06 amu.
What is isotope?Isotopes are elements with same atomic number and different mass numbers. Isotopes have similar chemical and physical properties.
The atomic mass of an element from the masses of its isotopes can be calculated using the equation given below:
Atomic mass = mass of isotope 1 × % abundance/100 + mass of isotope 2× % abundance/100
Here, the percentage abundance of Ga-69 is 60.11%. Thus percentage abundance of Ga-71 is 100 - 60.11 = 39.81 %. The atomic mass of gallium is 69.723 u.
Thus the mass of Ga-71 is calculated as follows:
69.723 = (68.9256 × 60.11 /100) + (m2 × 39.81/100)
mass of Ga-71= m2 = [ 69.723 - (68.9256 × 60.11 /100) ] / 39.81
= 71.06 amu.
Hence the mass of the isotope of gallium Ga-71 is 71.06 amu.

exactly 149.6J will raise the temperature of 10.0g of a metal from 25.0C. what is the specific heat capacity of the metal
Answers
Exactly 149.6J will raise the temperature of 10.0g of a metal from 25.0C. The specific heat capacity of the metal is 5.984 J/g°C.
What is specific heat capacity?The heat capacity of a sample of a substance divided by the mass of the sample yields the specific heat capacity (symbol c), also known as massic heat capacity. Informally, it is the quantity of heat that must be added to one unit of a substance's mass in order to raise its temperature by one unit. The specific heat capacity unit in the SI is the joule per kelvin per kilogram, or Jkg⁻¹K⁻¹. For instance, the specific heat capacity of water is 4184 J kg⁻¹K⁻¹, or the amount of energy needed to raise 1 kilogram of water by 1 K.
The specific heat capacity of the metal can be calculated using the equation Q = m × c ×ΔT.
Q = 149.6J
m = 10.0g
ΔT = (final Temperature - initial Temperature) = (25°C - 0°C) = 25°C
Plugging these values into the equation, we get:
149.6J = 10.0g × c ×25°C
Solving for c, we get:
c = \(\frac{149.6J}{(10.0g *25C)}\)
c = 5.984 J/g°C
Therefore, the specific heat capacity of the metal is 5.984 J/g°C.

What is the concentration (molarity) of a solution of NaCl if 350. mL of a 2.5 M NaCl solution is diluted to a total volume of 5.0 mL? (NEED HELP ASAP)
Answers
The concentration (molarity) of the final NaCl solution is 175 M.
To find the concentration (molarity) of the final NaCl solution, we can use the equation:
M1V1 = M2V2
Where M1 is the initial concentration, V1 is the initial volume, M2 is the final concentration, and V2 is the final volume.
In this case, we have an initial NaCl solution with a concentration of 2.5 M and a volume of 350 mL (0.350 L). We are diluting this solution to a total volume of 5.0 mL (0.005 L).
Plugging these values into the equation, we have:
(2.5 M) * (0.350 L) = M2 * (0.005 L)
Simplifying the equation:
0.875 = 0.005 * M2
Dividing both sides by 0.005:
M2 = 0.875 / 0.005
M2 = 175M

consider the reaction between mg s and hcl(aq) to produce aqueous magnesium chloride and hydrogen gas. How many liters of hydrogen gas at STP will be produced when 12.15 g of magnesium reacts with an excess of hydrochloric acid
Answers
Answer:
11.2L is the volume of hydrogen gas produced.
Explanation:
The reaction of Mg with HCl is:
Mg + 2HCl → MgCl₂ + H₂
Based on the reaction the moles of Magnesium are equal to moles of hydrogen produced, that is:
Moles Mg -Molar mass: 24.305g/mol-:
12.15g Mg * (1mol / 24.305g) = 0.500 moles of Mg = Moles of H₂
Now, using PV = nRT, where:
P is pressure -1atm at STP-
V is volume -Our incognite-
n are moles -0.500 moles of H₂-
R is gas constant -0.082atmL/molK-
And T is temperature -273.15K-:

Calculate the volume occupied by 35.2 g of methane gas (CH4) at 25°C and 1.0 atm. R = 0.08206 L*atm/Kxmol.
Answers
Answer:
53.7 L
Explanation:
The volume occupied by 35.2 g of methane gas at 25 °C and 1.0 atm. is 55.9 L.
Given to us is temperature, pressure, universal gas constant, and mass of methane gas, we need to find the volume occupied by the gas.
To calculate the volume occupied by the methane gas, we can use the ideal gas law equation:
PV = nRT
Where:
P = pressure (in atm)
V = volume (in liters)
n = number of moles
R = ideal gas constant (0.08206 Latm/(Kmol))
T = temperature (in Kelvin)
First, we need to convert the given temperature from Celsius to Kelvin:
T(K) = T(°C) + 273.15
T(K) = 25 °C + 273.15
T(K) = 298.15 K
Next, we calculate the number of moles of methane gas using its molar mass:
molar mass of CH₄ = 12.01 g/mol + 4(1.008 g/mol) = 16.04 g/mol
n = mass/molar mass
n = 35.2 g / 16.04 g/mol
n = 2.19 mol
Now we can substitute the values into the ideal gas law equation:
PV = nRT
V = (nRT) / P
V = (2.19 mol × 0.08206 Latm/(Kmol) ×298.15 K) / 1.0 atm
V = 55.9 L
Therefore, the volume occupied by 35.2 g of methane gas at 25 °C and 1.0 atm is 55.9 liters.

The boiling point of water is 100.0 °C, the boiling point of the solution will be : 101.49 °C.The correct answer is option (a) 100.00049 °C.
Ideal Solution : An ideal solution is a homogeneous mixture of two or more components that obeys Raoult's law, which states that each component's vapor pressure is proportional to its mole fraction.The boiling point of a solution depends on the solvent's properties and the solute's concentration. It's dependent on the mole fraction of the solvent and solute, as well as the total concentration of the solution. The change in boiling point of a solution is given byΔTb = Kb × m × i, whereKb = ebullioscopic constant, m molarity of the solution, and i = van't Hoff factor.Assuming that the solution's behavior is ideal, we may use the molality of the solution to compute the boiling point elevation of the solution.The molality of the solution is given by the following formula:m = (n₂ / m₂) ÷ (n₁ / m₁), where n is the number of moles, m is the mass, and the subscripts 1 and 2 refer to water and non-volatile solute sucrose, respectively.The molar mass of sucrose (C₁₂H₂₂O₁₁) is342.3 g/mol; therefore, the number of moles of sucrose is115.0 g ÷ 342.3 g/mol = 0.335 mol.m₁ = mass of water = 350.0 g, and m₂ = mass of sucrose = 115.0 g, as given in the problem.Therefore, the molality of the solution is given by:m = (0.335 mol / 0.115 kg) ÷ (1 mol / 1 kg) = 2.91 mol/kg.Substituting these values in the formula for ΔTb, we get:ΔTb = Kb × m = 0.512 °C m⁻¹ × 2.91 mol/kg = 1.49 °C.100.0 °C + 1.49 °C = 101.49 °C.

where V(N2O5) = 4.86 dm3 is N2O5's volume and Vm(N2O5) is N2O5's molar volume under the circumstances stated in the ideal gas law:
\((R*T)/P = Vm = V/n\)
when the gas constant R is used.
the kelvin scale of temperature, T
The pressure is P.
The ideal gas law:
\(n(N_2O_5) = V(N2O5) / Vm(N_2O_5) = 4.86 dm3 / (24.46 L/mol) = 0.1982 mol\)
the number of moles of NO2 is:
\(n(NO_2 = 4/2 * n(N_2O_5) = 0.3964 mol\)
then,
\(n(NO_2 = 4/2 * n(N_2O_5) = 0.3964 mol\)

can you pls tell me the net ironic equation of H₂²⁺(aq) + O₂²⁻(aq) + Mg²⁺(aq) + SO₃²⁻(aq) → Mg²⁺(aq)+SO²⁻₄(aq) + H₂O(l)
please its urgent
Answers
Answer:
H₂²⁺(aq) + O₂²⁻(aq) + SO₃²⁻(aq) → SO²⁻₄(aq) + H₂O(l)
Explanation:
H₂²⁺(aq) + O₂²⁻(aq) + Mg²⁺(aq) + SO₃²⁻(aq) → Mg²⁺(aq) + SO²⁻₄(aq) + H₂O(l)
A careful observation of the equation above, shows that the equation is already balanced.
To obtain the net ionic equation, we simply cancel Mg²⁺ from both side of the equation as shown below:
H₂²⁺(aq) + O₂²⁻(aq) + SO₃²⁻(aq) → SO²⁻₄(aq) + H₂O(l)
