The chemical equation that depicts a balanced chemical reaction is the one in choice B.

In this choice, the same number of atoms of each elements is in both, reactants and products sides, which means that the law of conservation of mass is fulfilled.

The correct answer is choice B.

The correct answer is 107.9 g of Ag is produced from a reaction of 31. 75 gram of Copper.

Molar mass of a substance is the mass in grams of one mole of the compound. A mole is the measurement of the number of things, such as atoms, molecules, and ions, that are present in a substance. Any material has 6.022 x 1023 molecules in a mole, it is known as Avogadro's number . The mole is used to determine the size of the tiniest entities quantitatively, just as we use a standard value to quantify many things, such as 1 dozen = 12 items.

Formula - Molar mass = mass in grams/mole = g/mol

Molar mass of a substance can be calculated as:

Given,

n = W/M, where

W = required mass

M= molar mas

Given chemical reaction is:

Cu + 2AgNO₃ → Cu(NO₃)₂ + 2Ag

From the stoichiometry of the reaction,

1 mole of Cu = produce 2 moles of Ag

Given mass of Cu = 31.75g

Molar mass of Cu = 63.5g/mol

Moles of Cu = 31.75g / 63.5g/mol = 0.5 moles

0.5 moles of Cu = produce 2×0.5 = 1 mole of Ag

Molar mass of Ag = 107.9g/mol

Required mass of Ag = 1mol × 107.9g/mol = 107.9 g

Answer:

That is correct. Atomic fission is the process of splitting the nucleus of an atom into two or more smaller nuclei using a neutron. This process releases a large amount of energy in the form of heat and radiation. On the other hand, atomic fusion is the process of combining two or more atomic nuclei into a larger, more massive nucleus. This process also releases a large amount of energy. Both processes involve a conversion of mass into energy, according to Einstein's famous equation E=mc². This means that a small amount of matter can be converted into a large amount of energy. The reverse process, where energy is converted back into mass, is also possible and is observed in nature, for example in the formation of particles and antiparticles

A substance's hue varies over time: Chemical transformation (Over time, the material is changing into a different chemical.

How can you tell whether a change you witness is chemical or physical?

In a physical change, the substance's shape or appearance changes, but the type of matter it contains stays the same. In contrast, when matter undergoes a chemical transformation, at least one new substance with novel features is created.

Not every change in colour results from a chemical shift. If one were to alter a substance's colour through a non-chemical interaction, such as painting an automobile, the alteration would be physical rather than chemical. This is due to the fact that the car's makeup has not changed.

The recommended pediatric iv dosage of furosemide is 1 mg/kg not to exceed 6 mg/kg. the child weighs 55 lb. available: furosemide 20 mg/2 ml. The child will receive approximately 2.5 mL of furosemide.

To determine the appropriate dosage of furosemide for the child, first convert their weight from pounds to kilograms.

1 lb = 0.453592 kg

55 lb × 0.453592 kg/lb ≈ 24.95 kg

Now, calculate the dosage using the recommended pediatric IV dosage (1 mg/kg):

24.95 kg × 1 mg/kg ≈ 24.95 mg

Since the dosage should not exceed 6 mg/kg:

24.95 kg × 6 mg/kg = 149.7 mg (maximum dosage)

Since the child's calculated dosage (24.95 mg) is less than the maximum dosage, it can be administered.

Next, determine the volume of furosemide to be given. The available concentration is 20 mg/2 mL. Use the proportion:

20 mg/2 mL = 24.95 mg/x mL

Solve for x:

x = (24.95 mg × 2 mL) / 20 mg ≈ 2.495 mL

Therefore,the dosage  of furosemide that will be received by the child is 2.5 mL

There are 354.5 grams of Cl in 555 g CaCl2.

To find the number of grams of Cl in 555 g CaCl2, we can use the molar mass of CaCl2 and the molar mass of Cl.

The molar mass of CaCl2 is 110.98 g/mol and the molar mass of Cl is 35.45 g/mol.
First, we need to find the number of moles of CaCl2 in 555 g:
555 g CaCl2 × (1 mol CaCl2 / 110.98 g CaCl2) = 5.00 mol CaCl2

Next, we need to find the number of moles of Cl in 5.00 mol CaCl2:

5.00 mol CaCl2 × (2 mol Cl / 1 mol CaCl2) = 10.00 mol Cl
Finally, we can find the number of grams of Cl in 10.00 mol Cl:
10.00 mol Cl × (35.45 g Cl / 1 mol Cl) = 354.5 g Cl
So, there are 354.5 grams of Cl in 555 g CaCl2.

Reactive oxygen species (ROS) are chemicals produced during normal cell metabolism that may cause cellular damage, leading to impaired functioning.

ROS are highly reactive molecules that contain oxygen and include compounds such as superoxide radicals (O2•−), hydrogen peroxide (H2O2), and hydroxyl radicals (•OH).

ROS are generated as natural byproducts of various cellular processes, including aerobic respiration and oxidative metabolism. While the body has defense mechanisms, such as antioxidants, to neutralize excess ROS, an imbalance between their production and elimination can result in oxidative stress. This imbalance can arise due to factors like environmental pollutants, radiation, certain medications, and lifestyle choices such as smoking or a poor diet.

Excessive ROS can attack and damage cellular components, including proteins, lipids, and DNA. This oxidative damage can disrupt normal cellular functions and contribute to various health conditions, including aging, neurodegenerative diseases, cardiovascular diseases, and cancer.

Understanding the role of ROS and oxidative stress in cellular damage is important for developing strategies to mitigate their harmful effects. Antioxidants, both endogenous and exogenous, play a crucial role in neutralizing ROS and reducing oxidative stress. Maintaining a balanced redox state is essential for cellular health and overall well-being.

The synthesis of aromatic 1,2-amino alcohols using a bienzymatic dynamic kinetic asymmetric transformation (bienzymatic DKAT) is a 3 step process involving synthesis of ketones, enantioselective reduction of lactols and synthesis of aromatic 1,2-amino alcohols

Step-by-step method :

Step 1: Synthesis of ketones

Starting with a ketone as the substrate, add the enzyme galactose oxidase (GOx) and an oxidant such as sodium periodate (NaIO4) to convert the ketone to a lactol. This transformation takes place at room temperature in a mixture of water and tetrahydrofuran (THF). The reaction mixture was then filtered to remove any precipitate, and the aqueous phase was extracted with ethyl acetate (EtOAc) to give the product in good yield.

Step 2: Enantioselective reduction of lactols

Use the enzyme alcohol dehydrogenase (ADH) and an NADH cofactor to perform an enantioselective reduction of lactols. This transformation takes place at room temperature in a mixture of water and isopropanol (IPA). The product is a chiral alcohol with high enantioselectivity.

Step 3: Synthesis of aromatic 1,2-amino alcohols

The chiral alcohol can be transformed into an amino alcohol using a reductive amination reaction with ammonia or an amine. This transformation takes place at room temperature in a mixture of water and ethanol (EtOH) or isopropanol (IPA). The resulting product is a 1,2-amino alcohol with high diastereoselectivity and enantioselectivity. This bienzymatic DKAT method is an effective and efficient way to synthesize aromatic 1,2-amino alcohols.

Thus, the step-by-step method of synthesis of aromatic 1,2-amino alcohols using a bienzymatic dynamic kinetic asymmetric transformation is explained above.

Increasing the temperature will shift the equilibrium of the system in the direction that consumes heat.

In this case, the forward reaction is exothermic, meaning it releases heat, so increasing the temperature will favor the reverse reaction.

N₂(g) + 2H₂O(g) + heat ⇌ 2NO(g) + 2H₂(g)

By increasing the temperature, the system will respond by attempting to counteract the temperature increase. It does so by shifting the equilibrium to the left, which is the endothermic direction. This means that more reactants (N₂ and H₂O) will be favored, resulting in a decrease in the formation of products (NO and H₂).

Therefore, increasing the temperature will shift the equilibrium towards the left, favoring the formation of more reactants (N₂ and H₂O) and reducing the concentration of products (NO and H₂).
