Birth weight is the weight of a baby at the time of birth. It is usually measured soon after delivery, with a special baby scale, though sometimes the baby's weight is estimated. The normal range of birth weight is anywhere between 5 lbs 8 oz and 10 lbs, though preterm or premature babies may be significantly lighter. A baby's birth weight is important because it can provide a clue to the baby's overall health. High birth weights may indicate an underlying medical condition, and low birth weights can be a sign of premature or difficult delivery and health risks associated with such a delivery.

Answer:

Explanation: First, convert the mass of graphite from milligrams (mg) to grams (g).

As 1,000 milligrams in 1 gram

therefore,

300 mg = 300/1000 = 0.3 grams

Now, we can use the molar mass of carbon to calculate the number of moles. We divide the mass of the sample by the molar mass:

Number of moles = Mass (g) / Molar mass (g/mol)

Number of moles = 0.3 g / 12.01 g/mol

Number of moles ≈ 0.02498 moles (rounded to five decimal places)

Therefore, there are approximately 0.02498 moles of carbon in 300 mg of graphite.

The amount of heat energy produced when 1 g of hydrogen and 2 g of nitrogen are reacted, is -6.61 KJ

First, we shall obtain the limiting reactant. Details below:

3H₂ + N₂ -> 2NH₃

From the balanced equation above,

28 g of N₂ reacted with 6 g of H₂

Therefore,

2 g of N₂ will react with = (2 × 6) / 28 = 0.43 g of H₂

We can see that only 0.43 g of H₂ is needed in the reaction.

Thus, the limiting reactant is N₂

Finally, we the amount of heat energy produced. Details below:

3H₂ + N₂ -> 2NH₃ ΔH = -92.6 KJ

From the balanced equation above,

When 28 grams of N₂ reacted, -92.6 KJ of heat energy were produced.

Therefore,

When 2 grams of N₂ will react to produce = (2 × -92.6) / 28 = -6.61 KJ

Thus the heat energy produced from the reaction is -6.61 KJ

Types of luminous flames:

1. Yellow Luminous Flame

2. Smoky Luminous Flame

3. Orange Luminous Flame

4. Blue Luminous Flame

Luminous flames are characterized by their visible glow, which is caused by the incomplete combustion of fuel. The presence of soot particles in the flame causes the emission of light. There are different types of luminous flames, which can be classified based on their fuel composition and burning conditions. Here are some common types of luminous flames:

1. Yellow Luminous Flame: This is the most common type of luminous flame, often seen in open fires, candles, and gas stoves. It appears yellow due to the presence of soot particles in the flame. Yellow flames indicate incomplete combustion of hydrocarbon fuels, such as methane, propane, or natural gas. The high carbon content in these fuels leads to the formation of soot, which emits visible light.

2. Smoky Luminous Flame: This type of flame is characterized by a significant amount of black smoke and soot production. It is commonly observed in poorly adjusted or malfunctioning burners or engines. The excessive presence of unburned fuel in the flame results in incomplete combustion and the emission of dark smoke particles.

3. Orange Luminous Flame: An orange flame indicates a higher combustion temperature compared to a yellow flame. It is often seen in more efficient burners or when burning fuels with a higher carbon content, such as oil or diesel. The higher temperature helps in burning more of the carbon particles, reducing the amount of soot and making the flame appear less yellow.

4. Blue Luminous Flame: A blue flame is typically associated with complete combustion. It indicates efficient burning of fuel, resulting in minimal soot formation. Blue flames are commonly observed in gas burners or Bunsen burners. The blue color is a result of the combustion of gases, such as methane, in the presence of sufficient oxygen.

It's important to note that the luminosity of a flame can vary depending on factors such as fuel-air mixture, combustion temperature, and the presence of impurities. Achieving complete combustion and minimizing the production of soot is desirable for efficient and cleaner burning processes.

Explanation:

The rise or fall of a fluid in a capillary tube is governed by the balance of cohesive and adhesive forces. Inermolecular forces are responsible for cohesion and adhesion. The narrower the bore of a glass tube, the greater the extent of raising or lowering of the liquid.

The polar molecule different from a non-polar molecule is  option A) Polar molecules have charges separated like poles of a magnet.

Polar molecules and non-polar molecules differ in terms of their distribution of electrical charge.  This results in an uneven distribution of charge, with one side of the molecule having a slightly positive charge (δ+) and the other side having a slightly negative charge (δ-).

This charge separation occurs when there is an uneven distribution of electrons within the molecule, resulting in a molecular dipole. The positive and negative charges are like the poles of a magnet, with one end being slightly positive (δ+) and the other end slightly negative (δ-).

In contrast, a non-polar molecule has an even distribution of electrons and does not have a significant separation of charges. The electrons are shared equally among the atoms in the molecule, resulting in a neutral overall charge and no distinct positive or negative ends.The correct answer is option A.

Answer: 0.00507 moles

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

\(Molarity=\frac{n\times 1000}{V_s}\)

where,

n = moles of solute

\(V_s\) = volume of solution in ml

1. moles of napthalene = \(\frac{3.09\times 0.001\times 100.0}{100}=0.000309moles\)

2. moles of methyl napthalene = \(\frac{10.0\times 0.001\times 100.0}{1000}=0.001mole\)

3. moles of dimethyl napthalene = \(\frac{23.2\times 0.001\times 100.0}{1000}=0.00232moles\)

4. moles of trimethyl napthalene = \(\frac{14.4\times 0.001\times 100.0}{1000}=0.00144moles\)

Thus total moles of all naphthalene compounds combined is (0.000309+0.001+0.00232+0.00144) = 0.00507.

To find the mass percent of the solution, we have to divide the mass of solute by the mass of solution and multiply it by 100.

The mass of solution will be the sum of the mass of the solute and the mass of the solvent:

The wavelength of light that should be employed for nickel(II) ion is roughly 400–500 nm, according to the absorbance spectra displayed. This is due to the graph's observation of an absorbance peak with a maximum of roughly 0.8 in this region.

The plot of a substance's absorbance as a function of light wavelength is called the absorbance spectrum. The absorbance spectrum in this instance is for the nickel(II) ion.

The peak in absorbance shows that the nickel(II) ion's electrons are most easily moved from a lower energy state to a higher energy one by this particular wavelength of light. As a result, more light is absorbed, increasing the measured absorbance.

Depending on the particular experiment and the tools being used, a specific wavelength of light should be employed. However, judging by the absorbance spectrum displayed, measuring nickel(II) ion absorbance should be possible at a wavelength of roughly 400–500 nm.

The actual yield is determined by calculating the quantity of the product created. We can estimate the percentage yield by dividing the actual yield by the theoretical value. The percentage yield is the difference between the quantity of product that was actually created and the maximum calculated yield.

2SO₂(g) + O₂(g) → 2SO3(g)

SO₂ mass => 364g

O₂ mass => 42g

SO3 mass => 408g

Theoretical yield of SO3:

mole of  O₂ => 42g/32g => 1.31

according to the chemical equation:

1 mole of oxygen => 2 moles of SO3

1.31 mole O2 => x moles of SO3

x=> 2 x 1.31 => 2.62

Hence, the mass of SO3 => 2.62 x 80.06 => 209.75g

The percentage of yield => Actual yield / theoretical yield x 100

                                  => 209.75/408 x 100 => 51.45 => 51.5%
