The statement about sub-atomic particles that is true is:

Electrons are the subatomic particles with the smallest mass; option B

What are sub-atomic particles?

Sub-atomic particles refer to the smaller particles that are the constituents of atoms of elements.

There are three sub-atomic particles within a given atom,

The three sub-atomic particles are given below:

electrons -electrons are the negatively charged particles found outside the nucleus of an atom in electron shells or orbitals around the atom.protons - these are positively charged particles found inside the nucleus of an atom. The number of protons in an atom gives the atomic number of that atom.neutrons - these are neutral atoms found in the nucleus of atoms. The sum of the neutrons and protons in the nucleus of an atom gives the mass number of an atom. This is because the mass of an at is centered inside the nucleus since the proton and neutron have equal mass but the electron has negligible mass.

A 0.15M solution of methylamine CH3NH2 contains an unknown concentration of methylamine chloride CH3NH3Cl. If the solution has a pH of 10.20,what is the concentration of methylamine chloride in the solution? Kb for methylamine=4.6*10^-4

Answers

Answer:

0.43 M

Explanation:

The equation that should be used in this case would be:
pOH = pKb + log([A+]/[Base])
pKb = -log (4.6*10^-4) = 3.34
pOH = 14-10.2 = 3.8
[Base] = 0.15
3.8 = 3.34 + log x/0.15
0.46=log x/0.15

The maximum amount of ethane (C₂H₆) that can be formed is 9.15 g.

The formula for the the limiting reagent is H₂

The amount of excess reagent that remains after the reaction is 3.86 g.

What is limiting reagent?

The limiting reagent is the reactant that is completely used up in a reaction, and thus determines when the reaction stops.

The limiting reagent is determined by balancing the chemical equation as follows;

H₂ + C₂H₄  --------> C₂H₆

From the reaction above;

1 mole of hydrogen gas = 1 mole of ethylene = 1 mole of ethane

2 g of hydrogen gas (H₂)  = 30 g of ethane (C₂H₆)

0.61 g of H₂ = ? of C₂H₆

= (0.61 x 30)/2

= 9.15 g of C₂H₆

Thus, the maximum amount of ethane (C₂H₆) that can be formed is 9.15 g.

The formula for the the limiting reagent is H₂ because it will be completely used up.

2 g of H₂ = 28 g of C₂H₄  -

0.61  of H₂ = ?

= (0.61 x 28)/2

= 8.54 g

Excess mass of the ethylene that remains = 12.4 g - 8.54 g = 3.86 g

The concentration of glucose (molar mass 180 g/mol) in the fluid of the spine is 75 mg / 100g of water. What is the molal concentration?

Answers

Considering the definition of molal concentration, the molal concentration of glucose is 0.004166  moles/kg.

Molal concentration or molality

Molality or molar concentration is a way of measuring the concentration of solute in solvent, that is, the number of moles of solute present in the solvent.

Molality is defined as the moles of a solute per kilogram of solvent.

The Molality of a solution is determined by the expression:

molality= number of moles of solute÷ kilogram of solvent

Molala concentration in this case

In this case, you know:

Molar mass of glucose= 180 g/molConcentration of glucose= 75 mg/ 100 g of waterMass of glucose= 75 mg= 0.075 g (being 1 mg= 0.001 g) Number of moles of solute= Mass of glucose÷ Molar mass of glucose= 0.0004166 molesMass of solvent = Mass of water= 100 g= 0.1 kg (being 1000 g= 1 kg)

Replacing in the definition of molal concentration:

molality= 0.0004166 moles÷ 0.1 kg

molality= 0.004166  moles/kg

Finally, the molal concentration in this case is 0.004166  moles/kg.

Answers

A small sample of chloride salts of group I metals on stirring with water on a beaker, at least some of the solid added will cease to be visible at the bottom of each beaker.

Group I elements are Hydrogen, Lithium, Sodium, Potassium, Rubidium, Cesium and Francium.

When chloride salts of these elements where dissolved in water it would not produce bubbles or change colour.

In addition to that, not all salts would feel hot to touch when the beaker in which the salt was dissolved is touched. Some would feel cool. This is because of difference in the process happening between the salt and water. For example: HCl would release heat when dissolved in water – Exothermic reaction (Beaker would be hot to touch) whereas KCl would absorb heat  when dissolved in water – Endothermic reaction (Beaker would be cool to touch).

One common thing about chloride salts of group I elements is that they all dissolve in water. The bond between the elements and the chloride is Ionic in nature. In the water, the bond between the molecules is covalent. The covalent bonds are stronger than ionic bonds. Thus, ionic bonds dissociate and covalent bonds would be formed with water and dissociated ions i.e., chloride salts are dissolved in water. When this happens, solid would cease to be visible at the bottom of each beaker.

Explanation:

H2O should deviate from ideal behavior the most. Remember that an ideal gas has molecules which don't interact. Argon exists as an monoatomic element in the gas state, and the atom is neutral throughout. This means that two argon atoms only interact with each other through London dispersion forces or bumping. However, water is polar, so water molecules will attract each other strongly through permanent dipole-dipole interactions and hydrogen bonding. This means that water vapor deviates from ideal behavior the most

The new pressure when the can is heated to 1235 °C is 4031.8 torr

we'llbegin by listing out the parameters obtained from the question. This is given below:

Initial pressure (P₁) = 770 torrInitial temperature (T₁) = 15 °C = 15 + 273 = 288 K New temperature (T₂) = 1235 °C = 1235 + 273 = 1508 KVolume = ConstantNew pressure (P₂) = ?

The new pressure can be obtained as illustrated below:

P₁V₁ / T₁ = P₂V₂ / T₂

Volume = contant

P₁ / T₁ = P₂ / T₂

770 / 288 = P₂ / 1508

Cross multiply

P₂ × 288 = 770 × 1508

P₂ × 288 = 1161160

Divide both sides by 288

P₂ = 1161160 / 288

P₂ = 4031.8 torr

A 68.0 mL portion of a 1.50 M solution is diluted to a total volume of 208 mL. A 104 mL portion of that solution is diluted by adding 161 mL of water. What is the final concentration? Assume the volumes are additive.

Answers

Taking into account the definition of dilution, after two dilutions the final concentration is 0.1923 M.

Dilution

When it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution. This is accomplished by simply adding more solvent to the solution at the same amount of solute.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume of the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

Ci: initial concentrationVi: initial volumeCf: final concentrationVf: final volume

Final concentration

In this case, you know for the first dilution:

Ci= 1.50 MVi= 68 mLCf= ?Vf= 208 mL

Replacing in the definition of dilution:

1.50 M× 68 mL= Cf× 208 mL

Solving:

(1.50 M× 68 mL)÷ 208 mL= Cf

0.49 M= Cf

Now, in a second dilution you take a sample of 104 mL of this diluted solution and add another 161 mL of water. The final volume of the solution will be

Vfinal= 104 mL + 161 mL= 265 mL

The concentration of the 104 mL sample is equal to the concentration of the first diluted solution, this is 0.49 M. Therefore, the concentration of the final solution will be:

0.49 M× 104 mL= Cf× 265 mL

Solving:

(0.49 M× 104 mL)÷ 265 mL= Cf

0.1923 M= Cf

In summary, the final concentration is 0.1923 M.

Answers

The density of a substance is calculated by taking the ratio of its mass and volume. The density of the diaphysis sample with a mass of 41 g is 0.725 g/cm³.

What is density?

Density is measure of mass of a substance per unit volume. Thus, mathematically it is mass divided by volume. Density of a substance is dependant on molecular weight, volume, temperature and bond type also.

Density of a substance may change with temperature. For example, the density if water is 1 g/L but it changes to maximum 4° C. A diaphysis sample is cylindrical in shape and have a volume of πr²l  where r is the radius and l be the length.

The volume of the diaphysis with a length of 8 cm and radius of 1.5 cm is calculated as follows:

Volume = πr²l

             = 3.14 × (1.5 cm)² × 8 cm

             = 56.52 cm³.

The density of the sample can be calculated by dividing the mass by volume as follows:

Density = mass / volume

             = 41 g/ 56.52 cm³

             = 0.725 g/cm³

Therefore, the density of the diaphysis sample is 0.725 g/cm³.
