10.0 g of nickel is cooled to 2.0 °C and
placed into a sample of warm water.
The final temperature of the water and
nickel was 63.4 °C. How much energy
is absorbed by the nickel?
J
CNi = 0.120 g. C
9Ni = [?] J

Answers

Answer 1

Answer:

73.68 J

Explanation:

To find the energy absorbed by nickel, you need to use the following equation:

Q = mcΔT

In this equation,

-----> Q = energy (J)

-----> m = mass (g)

-----> c = specific heat (J/g°C)

-----> ΔT = change in temperature

The change in temperature is found by subtracting the initial temperature from the final temperature. You can plug the given values into the equation and simplify to find the energy absorbed.

m = 10.0 g

c = 0.120 J/g°C

ΔT = 63.4 °C - 2.0 °C = 61.4 °C

Q = mcΔT

Q = (10.0 g)(0.120 J/g°C)(61.4 °C)

Q = 73.68  J

If the weight in gm of the sample is 0.040 moles of salt (NaCl) then Molar mass of NaCl = 58.44 g/mol.

Define molar mass?

The ratio between the weight and the amount of substance in any sample of a chemical compound is known as the molar mass of that compound. The molar mass of a compound is a bulk property instead of a molecular one.

By using formula: n=m / M m=n×M

m=(0.040)x(58.5) m=2.34g

So,

It means that if we prepare a 100cm3 solution using 2.34g of NaCl, the solution's concentration will be 0.500 mol/dm3.

What is melting point?

The temperature at which a substance transforms from a solid into a liquid is known as its melting point. The temperature at which a substance transforms from a solid into a liquid is known as its melting point. The balance between the solid and liquid phases is reached at the melting point. Pressure affects a substance's melting point, which is often reported at a standard pressure of 1 atmosphere, or 100 kPa. The melting point is the fixed temperature at which a solid transforms into a liquid. For instance, at 0°C, ice cubes begin to melt and turn from a solid to a liquid.

How do you find melting point?

By placing a small amount of an organic solid in a tiny capillary tube, affixing it to the stem of a thermometer centred in a heating bath, and gradually heating the bath, one may calculate the temperature at which melting begins and finishes. Melting points are frequently used to describe and rate the purity of organic and inorganic crystalline substances. Pure compounds melt at a fairly narrow temperature range of 0.5 to 1 °C, whereas contaminated, impure chemicals frequently show a huge melting gap.

Bonding theories are the vital postulates in chemistry that provide the basic information regarding the bonds present in a particular molecule. Three bonding theories are Lewis theory, valence bond theory, and molecular orbital theory. In Lewis theory, the electrons and lone pairs are symbolized as dots surrounding the atom. In valence bond theory, electrons are shared among orbitals of atoms, that forms bonds.  In molecular orbital theory, two atomic orbitals combine to make a molecular orbital. Bonding theories are very significant as they maintain the orientation in a bond. They provide information on the sort of bond present in the molecule, the sort of bonding taking place to form a simple or complex compound.

Molecular geometry is also known as the molecular structure. It is the three-dimensional structure or arrangement of atoms in a molecule. Helps to understand the molecular structure of a compound.

The formula for a substance is D4 and its molar mass is 30 g. A student is given 150 g of the substance and is asked how many atoms are in the sample. She says there are 5 times Avogadro's number (6.022 x 102) of atoms in her sample. The student is in error, identify her error and explain what the correct answer should be.

Answers

The student's error is that she is assuming that the number of atoms in a sample is directly proportional to the mass of the sample. Avogadro's number (6.022 x 10²³) represents the number of atoms or molecules in one mole of a substance. However, the number of atoms in a given mass of a substance depends on the molar mass (mass per mole) of the substance, not the Avogadro's number.

The correct way to determine the number of atoms in a sample is to use the formula:

number of atoms = mass of the sample / molar mass

In this case, the molar mass of the substance is 30 g/mol, so the number of atoms in 150 g of the substance is:

number of atoms = 150 g / 30 g/mol = 5 mol

The correct answer is 5 moles of atoms, which is not equal to 5 times Avogadro's number.

Draw the Lewis structure for CH5N. How many lone pairs does it have?

Answers

Lewis structure for CH₅N has one lone pair.

A lone pair, also known as an unshared pair or a non-bonding pair, is an unshared pair of valence electrons that are not shared with another atom in a covalent bond in chemistry. Atoms' outermost electron shell contains lone pairs. The Lewis structure can be used to locate them. Therefore, if two electron pairs are coupled but are not utilized in chemical bonding, they are referred to as lone pairs. As a result, the amount of valence electrons surrounding an atom is equal to the sum of the electrons in lone pairs and those in bonds.

In the valence shell electron pair repulsion theory (VSEPR theory), which describes the morphologies of molecules, the idea of a lone pair is employed. They are also mentioned in relation to Lewis acids and bases in chemistry. Chemists do not, however, always classify non-bonding electron pairs as lone pairs. Examples include transition metals, where non-bonding pairs are believed to be stereochemically inactive and do not affect molecular shape. The idea of a lone pair is less clear in molecular orbital theory (completely delocalized canonical orbitals or localized in some way), as the relationship between an orbital and the elements of a Lewis structure is sometimes not clear-cut. However, orbitals that are largely nonbonding or that are occupied are typically classified as lone pairs.

Turpentine (Csub10Hsub16) can react with chlorine gas to make carbon and hydrogen monochloride: Csub10Hsub16 (l) + 8Clsub2 (g) > 10C (s) + 16HCl (g) Suppose a chemist runs this reaction and makes 569g of carbon. How many grams of turpentine were consumed?

Answers

As per the given reaction, one mole or 136 g of turpentine produce 10 moles or 120 g of carbon. Then to produce 569 g of carbon 644.8 g of turpentine is required.

What is  theoretical yield?

The theoretical yield of a product in a reaction is determined using the balanced equation of the chemical reaction. Actual yield of the product might vary from the theoretical yield.

Given the balanced reaction of turpentine with chlorine gas producing carbon and HCl. Here, one mole of turpentine produces 10 moles of carbon.

molar mass turpentine  = 136 g/mol

atomic mass of carbon = 12 g/mol

mass of 10 moles = 120 g

136 g of turpentine produces 120 g of carbon. Then, mass of turpentine required to produce 569 g of carbon is :

(136 × 569) /120 = 644.8 g

Therefore, the mass of turpentine consumed in the reaction is 644.8 g.

Procter & Gamble is the manufacturer of Pampers diapers. At one time, the price of a typical package of diapers was relatively high (i.e., over $12 a package). Due to the threat of store brands stealing market share because of their lower price, P&G decided to lower the price for Pampers. While most consumers noticed the price reduction because P&G promoted that fact, what most of them did not notice was that the number of diapers per package also decreased. However, the reduction was only one or two diapers per package. Which of the following best explains why consumers did not notice the reduction in the quantity?Number of diapers per package was not important to consumers.The reduction in the quantity did not reach the level of a just noticeable difference.Price is more important than quantity to consumers.Consumers are price conscious for this product category.Consumers are brand loyal. in "static," an anonymous lubavitcher woman is unable to turn off her radio because she ___.

Imagine that researchers are conducting a randomized controlled trial of a high-fiber supplement as a preventive measure in persons at increased risk of type 2 diabetes. People enrolled in the study are disease-free at the time they agree to participate in the trial, but they all have a family history of type 2 diabetes and are considered at high-risk (80%) to develop the disease during their lifetime. The 10,000 participants who start the trial are healthy individuals who are randomly allocated to receive either high-fiber supplements or placebo for several years. As you can imagine, this study will be quite expensive and will require a large infrastructure of personnel and materials to carry it out successfully.Because type 2 diabetes has reached epidemic proportions in the United States, the potential benefits of this research are important at a population level. Unfortunately, high-fiber supplements have also been shown in a few studies to be associated with gastrointestinal blockage (which can be life-threatening) and reduced nutrient absorption, which may lead to anemia, osteoporosis, and other debilitating chronic diseases. The supplements may also reduce absorption of certain medications and cause gastrointestinal distress. The potential side effects of continuous high-fiber supplementation are only partially understood, and long-term effects are unknown.By Day 8Post your initial response to at least two of the following questions:What are the potential risks and benefits to be considered when designing this study?When the side effects and long-term effects of a potential preventive measure are largely unknown, is it ethical to expose participants to these risks?
