The options that affect the amount that the freezing point is lowered by the addition of the solute include :

The increasing of a solvent's boiling point as a result of the addition of a solute is known as boiling point elevation. Similar to freezing point depression, adding a solute lowers the freezing point of a solvent. In actuality, a solvent's freezing point drops as its boiling point rises.

Any solvent's freezing point will be lowered by the presence of a solute; this action is known as freezing-point depression. The fact that the solute is present in the liquid solution but not in the pure solid solvent is crucial to understanding this phenomenon.

This includes the compound being ionic or the solubility of the solvent.

84 oz of 2% acid solution and 48-84 = -36 oz of 10% acid solution must be mixed to make 48 oz of a 7% acid solution.

An acid solution is described as a liquid mixture that occurs when hydrogen ions are released when combined with water.

We have that  x oz of 2% acid solution be mixed with (48-x) oz of 10% acid solution.

The total amount of acid in the 2% solution is 2% * x oz = 0.02x oz.

The total amount of acid in the 10% solution is 10% * (48-x) oz = 1 * (48-x) oz.

The total amount of acid in the 48 oz mixture is 0.02x oz + 1 * (48-x) oz = 0.07 * 48 oz = 3.36 oz.

Hence we can calculate that :

0.02x + 1 * (48-x) = 3.36 and solve for x

0.02x + 48 - x = 3.36

0.02x - x + 48 = 3.36

Adding x to both sides:

0.02x + 48 = 3.36 + x

Subtracting x from both sides:

0.02x + 48 - x = 3.36

Dividing both sides by 0.02:

x = 84 oz

Answer:

In order to determine the mass of a substance given the volume, we require the density. The density of iron is 7.87 grams/cm³

Density = mass / volume

Mass = density * volume

Mass = 7.87 * 4.8

37.776 grams of iron are present in the cube

The density of the substance represents the relation of the mass to the volume of the substance. The mass of a pure iron cube of density 7.87 grams/cm³ is calculated to be 37.632 grams.

Mass is the amount of the substance contained that when gets divided by the volume in liters, milliliters or cubic centimeters gives the density of the substance. The mass of the substance can be in grams, kilograms, milligrams, etc.

The mass (m) is the multiplication product of the density (D) and volume (V) of the substance. Mass measures the amount whereas density measures the space occupied by the volume of the substance.

Given,

Density of iron cube (D) = 7.87 grams/cm³

Volume of cube (V) = 4.80 cm³

The formula is given as:

Density = mass ÷ volume

Mass = density × volume

Substituting values from above, the mass in grams of the iron cube is calculated as:

mass = 7.87 grams/cm³ × 4.80 cm³

mass = 37.632 grams

Therefore, the iron cube with a density of 7.87 grams/cm³ has a mass of 37.632 grams.

Answer:

Probably because chapstick can't really harm you and plus chapstick is used for dry crusty lips so why can't it be used for dry crusty hands and other parts of your body.

Explanation:

I saw that it could be used as lotion for small areas of dry skin like elbows or something but not full arms and legs.

Lotion is made to absorb into skin (that's why it's a liquidy substance), compared to chapstick thats made to lock in moisture on your lips (that's why it's a waxy stick). if you were to rub a bar of chapstick all over your arms and legs it wouldnt absorb nicely, and would leave your skin with a sticky waxy feeling.

Explanation:

First we convert 180 lb to kg:

Now we calculate the mass of antibiotic taken in one day:

Given that it is taken twice daily, in one day the person would take (652.8 * 2) 1305.6 mg. In grams that mass would be:

Finally we multiply those 1.3056 daily grams by the 14 days in two weeks:

The total mass of the antibiotic taken by a 180 lb person for the two-week period would be 18,252.8 mg.

An antibiotic is a type of antimicrobial substance used to treat bacterial infections. It is a medication that either inhibits the growth of bacteria or kills them outright.

Antibiotics work by targeting specific structures or functions in bacterial cells, disrupting their ability to replicate or causing them to die. They are an essential tool in modern medicine for treating various bacterial illnesses and have significantly contributed to improving human health by reducing the impact of infectious diseases.

To calculate the total mass of the antibiotic taken by a 180 lb person for a two-week period,

Convert the person's weight from pounds to kilograms:

Weight in kilograms = 180 lb × 0.453592 kg/lb

= 81.65 kg

Daily dosage = 8.0 mg/kg × 81.65 kg

= 653.2 mg

Total dosage for two weeks = Daily dosage × 2 (twice daily) × 14 (days)

= 18,252.8 mg

Answer:

bonding driven by ionic interactions.

Explanation:

When two equal forces act in opposite directions the result is that the forces are balanced and there is no motion. The process of moving or changing position. When one force is stronger than the other the result is motion.

An force results when one force is stronger than other forces and the motion of an object is affected is unbalanced force.

A force is an influence in physics that can change the motion of an object. A force can cause a mass object to change its velocity, or accelerate.

The forces are balanced if the people on each side of the rope pull with equal strength but in opposite directions.

As a result, there is no movement. Forces that are in balance can cancel each other out. The object does not move when there is a balanced force.

Forces out of balance, If one force is stronger than the others and their effects do not cancel out, the forces are unbalanced. Unbalanced forces alter motion, speed, and/or direction. A greater force results in a greater change in motion.

Thus, the answer is unbalanced force.

Water vapor has latent heat energy, which is absorbed or released during the process of changing states from liquid to gas or gas to liquid.When the sun's radiant energy hits the Earth's oceans, it causes the water molecules to absorb this energy and become more energized.

This leads to the water molecules breaking apart and transforming into water vapor, which is a gaseous state of water. Water vapor has a specific form of energy known as latent heat. This is the energy required to change the physical state of water from a liquid to a gas or from a gas to a liquid. The process of converting water into water vapor requires energy, and this energy is stored in the water vapor in the form of latent heat.

The amount of latent heat absorbed or released by water vapor is dependent on the temperature and pressure conditions. When the water vapor condenses back into liquid form, this latent heat is released into the atmosphere. This process plays a critical role in weather and climate patterns as it drives the movement of heat and moisture throughout the Earth's atmosphere.

In summary, water vapor has latent heat energy, which is absorbed or released during the process of changing states from liquid to gas or gas to liquid. This energy plays a vital role in the Earth's weather patterns and is a critical component of the Earth's energy balance.

Explanation:

The amount, in kJ, of heat needed to completely vaporize 50.0g of water at 100°C is 118.8 kJ.

The heat needed to completely vaporize 50.0g of water at 100°C can be calculated using the following formula:

q = m x Hv

where:

First, we need to convert 50.0g to moles by dividing by the molar mass of water which is approximately 18.015 g/mol3:

moles of water = 50.0 g / 18.015 g/mol moles of water = 2.776 mol

Thus:

q = (2.776 mol) x (40.65 kJ/mol) q = 112.8 kJ

In other words, 112.8 kJ of heat is needed to completely vaporize 50.0g of water at 100°C.
