A student has 20.0ml of 6.96 M CaCl2 solution the student adds water si the final volume of the solution is 250.0mL determine the new molarity of the solution

Answers

Answer 1
M1V1 = M2V2
BUT first convert the ml to L
20.0 ml % 1000 = 0.02 L
250 ml % 1000 = 0.25 L

M1V1 = M2V2
= 6.96x0.02 = M2x 0.25
= 0.14 = M2 x 0.25
M2 = 0.557

In dogs, there is a hereditary type of deafness caused by a recessive gene. Two dogs who carry the gene for deafness but have normal hearing are going to be mated. What is the genotype of the two parent dogs?

Answers

Since the two dogs are carriers of the gene for deafness, their genotypes would be "Hh", where "H" is the dominant gene for normal hearing and "h" is the recessive gene for deafness. This means that each of the dogs has one copy of the normal hearing gene and one copy of the gene for deafness, but they have normal hearing because the dominant gene is masking the effect of the recessive gene. When these two dogs are mated, they can pass on either the normal hearing gene or the gene for deafness to their offspring. The genotype of the two parent dogs would therefore be "Hh".

What are organic molecules?

In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive.

Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Living things incorporate inorganic carbon compounds into organic compounds through a network of processes (the carbon cycle) that begins with the conversion of carbon dioxide and a hydrogen source like water into simple sugars and other organic molecules by autotrophic organisms using light (photosynthesis) or other sources of energy. Most synthetically-produced organic compounds are ultimately derived from petrochemicals consisting mainly of hydrocarbons, which are themselves formed from the high pressure and temperature degradation of organic matter underground over geological timescales.  This ultimate derivation notwithstanding, organic compounds are no longer defined as compounds originating in living things, as they were historically.

What is molarity?

The method of figuring out how much of a material a certain chemical solution contains is known as molecularity, sometimes known as the molar concentration of a solution. It is measured by taking into account two indications, namely the volume of the solution and the quantity of solute molecules. Essentially, the volume of the solution is determined in liters. The letter "M" stands for molarity.

According to the given information:

Make use of the equation molarity = amount of moles / number of litres.

Rearrange the equations to read: no. of moles = no. of litres x molarity and no. of litres = no. of moles / molarity.

There are (0.215 x 1) = 0.215 moles of HCl in 215 ml of 1 M HCl (aq).

The volume of 12 M HCl (aq) containing 0.215 mol of HCl is equal to (0.215/12) = 0.0179 litre or 17.9 ml.

As a result, you would use 17.9 ml of 12 M HCl, which you would then dilute with water to get a total volume of 215 ml

Answers

The osmotic pressure of a solution that contains 0.026g of a hydrocarbon solute is 4.0 torr.

What is osmotic pressure?

Osmotic pressure is the pressure exerted by a solution due to the concentration of dissolved particles and the presence of a semipermeable membrane, which prevents the passage of some particles. This pressure can be present in both living and non-living systems. In living systems, osmotic pressure is the force that is responsible for the movement of water and other solutes across cell membranes. In non-living systems, osmotic pressure occurs when two solutions of different concentrations are separated by a semipermeable membrane. The higher the concentration of dissolved particles, the greater the osmotic pressure. Osmotic pressure plays an important role in the absorption and movement of water and other substances throughout the body. It is also important in industries such as food processing, pharmaceuticals, and biotechnology.

moles of solute=mass/molar mass =0.026/340g/mol=7.647×10⁻⁵

Molarity=moles/volume in solution

=7.647ₓ10⁻⁵/0.350L=0.000218M

The temperature of liquid in a cup with a lid changes less than in a cup without a lid.

How does a lid affect the temperature of liquid inside the cup?

It is well known that in a closed system, neither heat nor matter will be transferred from the system to the environment. In contrast, in an open system, energy and heat are exchanged from the system to its surroundings and vice versa.

Cup with the lid (cup A) is a closed system in this situation, but Cup without lid (cup B) is an open system. Therefore, there won't be any heat or material transfer from cup A to the system or surroundings. As a result, cup B warm up slowly.

The heat of combustion for sugar is 5639 kJ/mole, but that for TNT is 3406 kJ/mole. Why, if the heat of combustion for TNT is smaller than for sugar, is TNT an explosive?

Answers

Heat of combustion used to explain the relative stability of the compounds.

The heat of combustion definition is the variation in energy released in the form of heat through the burning of an amount of any substance, all reactants being in the standard state (temperature of 25 C and pressure of 1 atm).

When the amount is quantified for 1 mole of said substance, one can define this quantity as the molar heat of combustion.

The molar heat of combustion values are defined in kilojoules per mole (KJ/mol). The kilojoule is a unit of energy and corresponds to 1000 or Joules (J). Mole is a unit of measurement used to express the amount of matter.

Now sugar is a non electrolyte so comparatively more stable hence more energy required to decompose the sugar hence its heat of combustion value is -5639kJ/mol high.

Where as TNT used as an explosive so it is susceptible for reaction and combustion, hence low amount of heat of combustionnis required for TNT that is -3406kJ/mol whuch is comparatively lower.
