Which statement about aldehydes and ketones is correct?

A) In aldehydes, the carbon is always joined to at least one hydrogen atom.

B)Every ketone molecular formula is unique.

C) Aldehydes are similar to ketones, but their carbonyl group is located in the middle of the carbon chain.

D) In ketones, the carbon of their carbonyl group is bonded with one other carbon.

Answers

Answer 1

Answer:

A) In aldehydes, the carbon is always joined to at least one hydrogen atom.

Explanation:

Aldehydes and Ketones are organic compounds.

The main difference between them is that aldehydes have the carbon atom attached to at least one hydrogen atom.

In ketones, the carbon is attached to another carbon.

The IUPAC names of alkanals usually end with -eFor alkanones usually end with -one

To reiterate, the striking difference between the two families is that in alkanals, a hydrogen atom is directly attached to the carbonyl group while in alkanones, no hydrogen atoms is attached to the carbonyl group but two bulky alkyl groups.

Rubbing alcohol or isopropanol can be described by the chemical formula C3H7OH. One milliliter of isopropanol has a mass of 0.76 g, so its density is 0.76 g/mL. Isopropanol is often used as a cleaner or a disinfectant and evaporates when placed on warm objects. However, caution must be taken when using isopropanol, because it is also highly flammable. Which of the following is a chemical property of isopropanol?
A. One mL of isopropanol has a mass of 0.76 g.
B. Isopropanol has a density of 0.76 g/mL.
C. Isopropanol evaporates when placed on a warm object.
D. Isopropanol is flammable.

A chemical property of isopropanol : D. Isopropanol is flammable.

Further explanation

There are changes that occur in the mater: physical changes and chemical changes

Classification uses the principle of the initial and final state of the substance.

Physical changes do not form new substances, so the properties of the particles remain the same.(size,volume,shape)

Example : boiling and freezing, just change its phase form from liquid to gas or from liquid to solid

 

Chemical changes/reaction form new substances(products) that are different from the initial substances(reactants)

Example : toxic, corroded

So :

the physical properties of isopropanol :

mass, density, evaporation

the chemical properties of isopropanol :

highly flammable

Answer:

D. Isopropanol is flammable.

Explanation:

Mass, volume, temperature, phase of matter, color, texture, density, and hardness are all examples of physical properties. However, flammability is an example of a chemical property.

Chemical properties describe an object's potential to change its chemical composition. These properties depend on the types of atoms found in the object and the arrangement of those atoms (and their subatomic particles).

What is force and motion

Answers

force is a strength or energy as an attribute or physical action or movement, motion is the action or process of moving or being moved

Answer:

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes beginning moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull.

Considering the principles of KMT, which scenario would result in an increase of particles effective collisions at STP None of the above None of the above In a balloon In a balloon A container with large volume A container with large volume A container with small volume

Answers

Answer:

A container with small volume

Explanation:

The question is obviously incomplete because the image attachments are missing.

However, it is necessary to note that, the effective collisions depends on the volume of the gas.

The lesser the gas volume, the greater the effective collision between particles at STP.

Hence from the KMT, the scenario having the least volume of gas will have the greatest magnitude of effective collisions.

What factors are included on a phase diagram?
O A. Temperature and pressure
O B. Pressure and volume
O C. Mass and volume
O D. Heat and kinetic energy

Answers

Answer:

A. Temperature and pressure

Explanation:

The factors included in a phase diagram are the temperature and pressure conditions.

A phase diagram is a combined plot of three curves all in equilibrium;

Solid- liquid, liquid -gas, and solid -gas plots

On the vertical axis, we usually have the pressureOn the horizontal axis is where the temperature is represented. Most phase diagrams are used in chemistry and mineralogy to show areas in which different phases can exist at equilibrium.

The factors included on a phase diagram are temperature and pressure and the correct option is option A.

A phase diagram is a graphical representation that shows the different phases of a substance (solid, liquid, and gas) as a function of temperature and pressure. It provides valuable information about the conditions at which different phases can exist and the boundaries between them.

The temperature is typically plotted on the horizontal axis, while the pressure is plotted on the vertical axis.

By examining a phase diagram, one can determine the melting point, boiling point, and critical point of a substance, as well as the regions of stability for each phase. Additionally, phase diagrams can reveal the existence of phase transitions such as melting, boiling, and sublimation.

Thus, the ideal selection is option A.

Answer:

Aa 50% Widow's peak, aa 50% no Widow's peak

Explanation:

In the crossing over the phenotypes of their children, 50% are widow's peak (aa), while 50% are not widow's peak (Aa) because the widow's peak genes only show trait when it is in recessive condition.

What is a recessive condition?

An inheritance pattern known as autosomal recessive inheritance allows a genetic disease or characteristic to be transferred from parent to offspring.

When a kid receives one altered (mutated) gene from each parent, a genetic disease may result. An autosomal recessive disorder is typically not present in the parents of a kid who has it.

You have a solution of water and pure ethanol. The boiling point of water is 100 degrees Celsius and the boiling point of pure ethanol is 78 degrees Celsius. A. What process would you would use to separate this solution? Describe, in detail, how this process works.

Answers

Answer:

Distillation

Explanation:

A solution of water and ethanol are miscible. Hence, they can only be separated by a process known as distillation. Distillation is the process in which two or more constituents in a mixture are separated based on there difference in boiling points. The mixture is subjected to high heat and the one with the least boiling point distills/evaporates out first followed by the next least boiling point.

From the explanation above, it can be deduced that ethanol (with boiling point of 78°) will be distilled out while water remains in the boiling tube or container.

Mark is in charge of making change at his family's garage sale on a hot summer day. He runs low on change and brings out a jar of pennies from the house. He keeps the lid off of the jar. Later in the day, he notices that the pennies are hot. Which statement best explains what happened?\

Answers

Answer:

This question is incomplete

Explanation:

The question is incomplete without the options. However, when a metal (in this case what the pennies are made of) is left in direct contact with the heat from the sun, it conducts this heat and becomes hot. This process is called thermal conduction. The thermal energy is readily accepted by the material in which the pennies are made of thereby increasing the thermal energy of the penny coin  which then makes the pennies hot after being left under the sun.

The heat required to raise the temperature of 12g of water from 16 C to 21 C is:
a) 60 J
b) 60 cal
c) 50 cal
d) 50 J

Answers

Answer:

The correct option is;

b) 60 cal

Explanation:

The mass of the given water, m = 12 g

The initial temperature of he given water = 16°C

The final temperature of the given water = 21°C

The specific heat capacity of water, c = 4.184 J/(g·°C) = 1 cal/(g·°C)

The amount of heat, ΔQ, required = Mass × Specific heat capacity × Change in temperature

ΔQ = 12 × 4.184 × (21 - 16) = 251.04 J

Similarly, we have;

ΔQ = 12 g × 1 cal/(g·°C) × (21 - 16)°C = 60 cal

The amount of heat required = 60 cal.
