what is purpose of fine sand filter in purification of water
Anyone know this question
Answer:
Second option. 3
Explanation:
In order to balance a equation you need to have the same amount of atoms/moles in both sides.
Na₃PO₄ + _ HCl → 3NaCl + H₃PO₄
In reactant side we have 3 Na and we have the same amount in product side.
We also have 1 P and 4 O in both sides of the equation.
As we have 3 moles of NaCl in product side, this means we have:
NaCl → Na⁺ + Cl⁻
3 moles of Na⁺ and 3 moles of Cl⁻. In conclussion we need 3 moles of Cl⁻ in reactant side.Then, the stoichiometry of HCl must be, 3.
3 moles of HCl means that we have 3 moles of protons (H⁺).
HCl → H⁺ + Cl⁻
If you see the phosphoric acid, we also have 3 moles of protons.
H₃PO₄ → 3H⁺ + PO₄³⁻
Complete balanced equation is:
Na₃PO₄ + 3HCl → 3NaCl + H₃PO₄
A sample of n2o gas has a density of 3.10 g/l at 298 k.what must be the pressure of the gas (in mmhg)?
P=___mmHg
The pressure of N2O gas at a density of 3.10 g/L and a temperature of 298 K is 751 mmHg. To calculate the pressure of the N2O gas at a given density and temperature, we can use the ideal gas law: PV = nRT.
We know that the density of the gas is 3.10 g/L, and the temperature is 298 K. To find the pressure, we can assume that the volume of the gas is 1 L, and solve for pressure. where P is the pressure of the gas, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.
The density of a gas can be converted to moles using the formula:
Density = m/V
m = Density*V
Now we can use the ideal gas law to calculate the pressure:
P = (mRT)/V
R is the ideal gas constant = 0.0821 L atm K^-1 mol^-1
P = (3.10g0.0821 L atm K^-1 mol^-1298 K)/1 L
P = 751 mmHg

How the structure of molecule affects physical properties?
The structure of a molecule affects its physical properties because the arrangement of the atoms in the molecule determines the type of forces that interact between molecules.
And that forces affect how the molecules move and interact with each other. This, in turn, affects the physical properties of the molecule, such as its melting point, boiling point, polarity, and solubility.
For example, when a molecule has a higher number of non-polar bonds due to symmetrical structures, it will be less polar overall and have fewer attractive forces acting between molecules, resulting in a higher boiling point and lower solubility.
On the other hand, a molecule with a higher number of polar bonds due to asymmetrical structures will be more polar overall, leading to stronger attractive forces acting between molecules, resulting in a lower boiling point and higher solubility.

A sample of methane collected when the temp was 30 C mmHg measures 398 mL. What would be the volume of the sample at -5 C and 616 mmHg pressure
A sample of methane collected when the temp was 30 C and 760mmHg measures 398 mL. What would be the volume of the sample at -5 C and 616 mmHg pressure
Answer:
434.32mL
Explanation:Using the combined gas law:
[tex]\frac{PV}{T}[/tex] = k
Where;
P = Pressure
V = Volume
T = Temperature
k = constant.
It can be deduced that:
[tex]\frac{P_1V_1}{T_1}[/tex] = [tex]\frac{P_2V_2}{T_2}[/tex] = k ---------------------(i)
Where:
P₁ and P₂ are the initial and final pressures of the given gas
V₁ and V₂ are the initial and final volumes of the given gas
T₁ and T₂ are the initial and final temperatures of the gas.
From the question:
the gas is methane
P₁ = 760mmHg
P₂ = 616mmHg
V₁ = 398mL
V₂ = ?
T₁ = 30°C = (30 +273)K = 303K
T₂ = -5°C = (-5 +273)K = 268K
Substitute these values into equation (i) as follows;
[tex]\frac{760*398}{303}[/tex] = [tex]\frac{616*V_2}{268}[/tex]
Solve for V₂
V₂ = [tex]\frac{760*398*268}{616*303}[/tex]
V₂ = 434.32mL
Therefore, the volume of the sample at -5C and 616mmHg pressure is 434.32mL

Mass of alcohol = 19.7325 gVolume of alcohol = 25 mLDensity = ?Density = mass / volume
Density of alcohol = 19.7325 / 25
Density of alcohol = 0.7893 g/mL
Next, we shall determine the volume of the alcohol in the 25 mL flask. This can be obtained as follow:
Density of alcohol = 0.7893 g/mLMass of metal beat = 25.1060 gTotal mass of metal beat and alcohol = 38.6794 gMass of alcohol in flask = 38.6794 - 25.1060 = 13.5734 gVolume of alcohol in flask =?Volume = mass / density
Volume of alcohol in flask = 13.5734 / 0.7893
Volume of alcohol in flask = 17.2 mL
Finally, we shall determine the density of the metal beads. Details below:
Mass of metal beat = 25.1060 gVolume of alcohol in flask = 17.2 mLVolume of flask = 25 mLVolume of metal beads = 25 - 17.2 = 7.8 mLDensity of metal beads =?Density = mass / volume

An extremely efficient enzyme has a small KM and a large kcat.
The conversion rate at the lowest substrate concentration is measured in kcat/km. This interpretation is accurate. kcat/Km is a good indicator of an enzyme's effectiveness since it takes into account both the enzyme's maximum rate, kcat, and its affinity for its substrate (Km).The turnover number, or the number of molecules that may be created per second per active site, of an enzyme is provided by the formula k c a t / kM.Because the substrate concentration is almost usually much greater than the Km, in many situations, enzymes are only better when they have a larger kcat. It seems disingenuous to me to use the ratio when this is plainly the case, yet it still happens much too frequently. It could serve as a useful benchmark when compared to enzymes in particular situations.

The order of increasing radius is: Na+ < Rb+ < Br-
The radius of an atom or ion is a measure of the size of the atomic nucleus and the electron cloud that surrounds it. The radius of an atom or ion can be affected by various factors such as the number of protons, neutrons and electrons it has, as well as the electron configuration. In general, as we move from left to right across the periodic table, atomic radius tends to increase.
In the case of the three ions you provided, Br-, Na+ and Rb+ , the order of increasing radius is as follows:
Na+ has the smallest atomic radius among the three, as it has lost one electron and become a positive ion, the removal of the electron increases the effective nuclear charge, making the electron cloud more tightly held.
Rb+ has a slightly larger atomic radius than Na+ as it has one more electron and one more proton in its nucleus than Na+, making the electron cloud slightly less tightly held.
Br- has the largest atomic radius among the three as it has gained an electron and become a negative ion, the addition of the electron decreases the effective nuclear charge, making the electron cloud less tightly held.
