An organic compound containing 40% carbon, 6.67% hydrogen and rest of oxygen, has the molecular mass 180g.mol-1. Find out the EF as well as MF of the compound.
Answer:
The EF of the compound is CH2O and the MF is C6H12O6.
Explanation:
To find the empirical formula (EF) of the compound, we need to determine the simplest whole number ratio of the atoms in the compound. We can assume we have 100 g of the compound, which means we have:
40 g of carbon
6.67 g of hydrogen
53.33 g of oxygen (since the rest of the compound is oxygen)
Next, we can convert the masses to moles:
Moles of carbon = 40 g / 12.01 g/mol = 3.33 mol
Moles of hydrogen = 6.67 g / 1.01 g/mol = 6.61 mol
Moles of oxygen = 53.33 g / 16.00 g/mol = 3.33 mol
We then divide each of the mole values by the smallest number of moles, which is 3.33, to get the simplest whole number ratio:
Carbon: 3.33 / 3.33 = 1
Hydrogen: 6.61 / 3.33 = 1.98 (rounded to 2)
Oxygen: 3.33 / 3.33 = 1
So the EF of the compound is CH2O.
To find the molecular formula (MF), we need to know the molecular mass of the EF. The empirical formula mass (EFM) of CH2O is:
EFM = (1 x 12.01 g/mol) + (2 x 1.01 g/mol) + (1 x 16.00 g/mol) = 30.03 g/mol
We can then calculate the molecular formula mass (MFM) by dividing the given molecular mass (180 g/mol) by the EFM:
MFM = 180 g/mol / 30.03 g/mol = 6
This means the MF is 6 times the EF, or C6H12O6. Therefore
magnesium has an hcp crystal structure, a c/a ratio of 1.624, and a density of 1.74 g/cm3. compute the atomic radius for mg.
The atomic radius of magnesium is approximately 1.736 Å. This can be calculated using the formula: Atomic Radius = (a / 2) * sqrt(3), where a is the lattice parameter for the hcp crystal structure.
To calculate the atomic radius of magnesium, we can use the following formula:
Density = (2 * Atomic Mass) / [(a²) * (c / a) * Na]
where:
Density is the density of magnesium
Atomic Mass is the atomic mass of magnesium
a is the lattice parameter for the hcp crystal structure
c/a is the ratio of the height of the unit cell to the base length of the unit cell
Na is Avogadro's number
We can rearrange this formula to solve for the atomic radius:
Atomic Radius = (a / 2) * sqrt(3)
where:
a is the lattice parameter for the hcp crystal structure
Now, let's plug in the values given in the problem:
Density = 1.74 g/cm3
c/a = 1.624
Na = 6.022 x 10²³ molecules/mol
The atomic mass of magnesium is 24.305 g/mol.
To find the lattice parameter, we can use the fact that the volume of the unit cell is given by:
Volume = a² * (c / a) * sqrt(3) / 2
The density is also related to the volume and the atomic mass by:
Density = Atomic Mass / Volume
We can combine these two equations and solve for a:
a = (4 * Atomic Mass / (sqrt(3) * Density * c))⁽¹/³⁾
Plugging in the values:
a = (4 * 24.305 g/mol / (sqrt(3) * 1.74 g/cm^3 * 1.624))⁽¹/³⁾
a = 3.209 Å
Now we can calculate the atomic radius:
Atomic Radius = (a / 2) * sqrt(3)
Atomic Radius = (3.209 Å / 2) * sqrt(3)
Atomic Radius = 1.736 Å (rounded to three significant figures)
Therefore, the atomic radius of magnesium is approximately 1.736 Å.

What is molar ratio of Mg reacted to H2 produced? what is the stoichiometric ratio between the mg ribbon reactant and the hydrogen gas product?
The molar ratio of Mg reacted to H2 produced is 1:1. This means that for every mole of Mg that reacts, one mole of H2 is produced. The stoichiometric ratio between the Mg ribbon reactant and the hydrogen gas product is also 1:1.
This ratio is determined by the balanced chemical equation for the reaction between Mg and HCl, which is Mg + 2HCl → MgCl2 + H2. The coefficients in this equation represent the number of moles of each reactant and product that are involved in the reaction. The coefficient for Mg is 1, indicating that one mole of Mg reacts with two moles of HCl to produce one mole of H2 and one mole of MgCl2.
The stoichiometric ratio is important because it allows us to determine the number of reactants or products needed in a reaction. For example, if we know the amount of Mg we have, we can use the stoichiometric ratio to calculate the amount of H2 that will be produced. Similarly, if we know the amount of H2 we need, we can use the stoichiometric ratio to determine how much Mg we need to react with HCl to produce the required amount of H2.

Calculate the [H3O+] for 0.0087 M H2SO4
Answer in units of M
0.0174 M is the calculated [H₃O+] for 0.0087 M H₂SO₄. Molarity is an important concept in chemistry.
What is molarity?Molarity, which is defined as the number of moles of solute dissolved per liter of solution, is a measure of a solution's concentration. It is often written with the symbol "M" and is measured in moles per liter (mol/L) units.
The molarity of a solution is determined by dividing the volume of the solution in liters by the number of moles of the solute present in that volume. because it allows us to quantify the amount of substance present in a solution. It is frequently used in stoichiometric calculations to determine the amounts of a chemical reaction's reactant and product that should be known. For instance, if a solution contains 2 moles of solute dissolved in 1 liter of solution, the molarity of the solution is 2 mol/L.
Because it fully dissociates in water, H₂SO₄ is a powerful acid that produces two H+ ions for every molecule that dissociates. As a result, the [H₃O+] in a solution of 0.0087 M H₂SO₄ is twice as molten as the H₂SO₄ solution: [H₃O+] = 2 x [H+] = 2 x 0.0087 M = 0.0174 M.
Accordingly, the [H₃O+] of a H₂SO₄ solution containing 0.0087 M is 0.0174 M.

what is the polarity of slime molecules
Slime is a non-Newtonian fluid and does not have a molecular structure that can be considered polar or non-polar. The term "polarity" typically refers to the distribution of electrical charge within a molecule. In the case of slime, the material is made up of polymer molecules, which are long chains of repeating units. These polymer molecules interact with each other through hydrogen bonding, which gives the material its unique properties such as being a non-Newtonian fluid. However, these interactions are not based on polarity, so it is not appropriate to describe slime as being polar or non-polar.
Answer:
The polarity of slime molecules depends on the specific type of slime. There are many different types of slime, each made up of different types of molecules.
For example, if we consider a typical type of slime made from polyvinyl alcohol (PVA), the polarity of the PVA molecules will depend on their molecular structure and the type of bonding between the atoms. PVA is a synthetic polymer made up of repeating units of vinyl alcohol, which has a polar hydroxyl group (-OH). As a result, PVA is considered to be a polar molecule.
However, the overall polarity of a slime made from PVA will also depend on the other ingredients that are present, such as borax, which is often used as a cross-linking agent to form the slime. The overall polarity of the slime will also depend on the conditions it is in, such as the temperature, pH, and the presence of other substances that could affect the polarity of the slime.
In summary, the polarity of slime molecules can be complex and depends on the specific type of slime, the ingredients that make it up, and the conditions it is in.

sodium ion concentration in the cytoplasm of a neuron __________ when its sodium channels open.
The sodium ion concentration in the cytoplasm of a neuron increases when its sodium channels open.
This is because the opening of the sodium channels allows for the influx of sodium ions into the cytoplasm, leading to an increase in the content-loaded sodium ion concentration within the cell. As a result, the cytoplasm becomes more positively charged, which can lead to the generation of an action potential and the transmission of a nerve impulse.

What is compound interest ?Compound interest is the interest on normal interest. Compound interest for an amount p for a n years with a rate of interest R% can be calculated as follows:
A = P [1 + r/100]ⁿ
Given that, the amount p = $4200
rate of compound interest = 2.1 %
time period n = 2 months, it is 0.16 years.
Now the compound interest for two months = $ 4200× [1 + 2.1/100]^0.16 - $4200 = $13.98
Now, the amount after two months will be $ 4213.9.
Therefore, there will be $4213.9 in the account after two months.

How many moles of glucose did your body consume if you exhale 100 grams of carbon dioxide?
C6H12O6 + 6O2 = 6CO2 + 6H2O
24 g of pure CO2 are exhaled by the individual. To calculate the number of moles, divide the outcome by the molar mass. As a result, the individual exhales about 0.55 moles of carbon dioxide every hour.
What impact on glucose molecule due to exhale of Co2?During aerobic cellular respiration, the interaction of glucose and oxygen results in the production of ATP that the cell can utilize.
As by-products, water and carbon dioxide are produced. The general formula for aerobic cellular respiration is: During cellular respiration, oxygen and glucose combine to create ATP.
CO2 is converted to glucose during photosynthesis, and H2O is oxidized to produce oxygen. Cellular respiration involves the reduction of oxygen and the oxidation of glucose to produce CO2 and water.
CO2 is carried by the bloodstream to the lungs, where it is eventually exhaled out of the body.
Therefore, Hence Number of moles glucose, C6H12O6 = 100g/180g = 0.55 moles.

which solution has a lower vapor pressure? a 0.4m ch4 solution all four solutions given have the same vapor pressure a 0.4m sucrose solution a 0.2m kno3 solution a 0.2m nacl solution
Comparing the four solutions above, the vapour pressure of a 0.4 M CH4 (methane) solution is lowest. This is due to the fact that a solution's vapour pressure is directly inversely proportional to the mole fraction of the solvent.
When the rate of evaporation and condensation are equal, the pressure that a substance's vapour exerts in a closed container is referred to as vapour pressure. It is an indicator of a substance's propensity to evaporate and is influenced by variables including temperature, surface area, and intermolecular forces. A substance with a higher vapour pressure will evaporate more quickly than a substance with a lower vapour pressure at a given temperature. Chemistry, physics, and material science are just a few of the scientific and engineering disciplines where vapour pressure is an important feature. It has significant effects on how liquids and gases behave, including boiling temperatures, distillation, and phase transitions.
