The polar end of soap can be bonded with the polar end of water. Hence it can be mixed with water and can be washed away. Hence, option D is correct.
What is the action of soap in water?Soap is acting as a surfactant in water and oily surface of dirt. A lengthy chain of fatty acids is saltified with sodium or potassium to form a soap molecule. Soap is made up of two components: an ionic component and a long carbon chain.
The characteristics of the two molecules that make up soap are highly dissimilar. These two pieces are referred to as soap's hydrophobic tail dissolves in oils and is naturally water-repellent. It has an ionic makeup.
The second part hydrophilic head, or water-loving portion of the soap molecule, dissolves in water. It is composed of a very long hydrocarbon chain. Therefore, the hydrophilic head of soap molecule easily binds with water and can be washed away.

Explanation:
20 ML of a gas at 200 K is heated until the new volume is 55ML what is the final temperature of the gas
Answer:
T2 = 550K
Explanation:
From Charles law;
V1/T1 = V2/T2
Where;
V1 is initial volume
V2 is final volume
T1 is initial temperature
T2 is final temperature
We are given;
V1 = 20 mL
V2 = 55 mL
T1 = 200 K
Thus from V1/T1 = V2/T2, making T2 the subject;
T2 = (V2 × T1)/V1
T2 = (55 × 200)/20
T2 = 550K
what is the ionic compound for sodium oxide
Answer:
Na2O
Sodium Oxide (Na2O)
Explanation:
Sodium oxide (Na2O) is an ionic compound. Its constituent atoms are, respectively, a metal and a non-metal. ... Sodium (Na), as a metal, will attempt to lose electrons to reach an octet state.
The resulting ionic compound, Na₂O, consists of positively charged sodium ions (Na⁺) and negatively charged oxide ions (O²⁻).
The ionic compound for sodium oxide is "sodium oxide" itself. In the ionic compound's formula, the metal (sodium) comes first, followed by the non-metal (oxygen). Sodium is an alkali metal with a charge of +1, and oxygen is a non-metal with a charge of -2.
The chemical formula for sodium oxide is Na₂O.
In this ionic compound:
Sodium (Na) loses two electrons to become Na⁺ (cation).
Oxygen (O) gains two electrons to become O²⁻ (anion).
The resulting ionic compound, Na₂O, consists of positively charged sodium ions (Na⁺) and negatively charged oxide ions (O²⁻).

Three reasons why friction is needed
Answer:
1:Without friction, we would not be able to stop walking since we would just keep slipping like on ice.
2:Without friction, objects would just slip and fall with a simple blow of air
3:And finally, without friction, we wouldn't be able to use machinery like cars and etc since they would just fly off
Explanation:
Friction can be a useful force because it prevents our shoes from slipping on the pavement when we walk and stops car tires skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding. Sometimes we want to reduce friction.

A 800 kg car zooms away from a red light with an acceleration of 7.6 m/s2. What is the
average net force in Newtons that the car experiences?
Answer:
6080 N
Explanation:
From the question given above, the following data were obtained:
Mass (m) of car = 800 Kg
Acceleration (a) of car = 7.6 m/s²
Force (F) =?
The force experienced by the car can be obtained as illustrated below:
Force (F) = mass (m) × acceleration (a)
F = m × a
F = 800 × 7.6
F = 6080 N
Thus, the experience a force of 6080 N
Transpiration meaning and examples
Explanation:
Transpiration is the movement of water through plants using the xylem and also their loss from plants surfaces.
Water is a lost from plants from the leaves and the stomata. This water is usually replaced by the absorption of water by the root.
Transpiration is an important part of the water cycle in the biosphere. Significant amount of water is lost from plant in the process of transpiration. Transpiration water condenses in the atmosphere to form rain clouds.An example of transpiration when water loses water from their leaves.

Which of these best describes a flight that is approaching the speed of
sound?
A. More drag is created because the air molecules are not moving
out of the way of the airplane.
B. Subsonic speeds help the engines work more efficiently.
C. Less lift is created because there are fewer air molecules.
O D. There is not enough thrust to propel the airplane past the sound
waves.
Answer:
More drag is created because the air molecules are not moving out of the way of the airplane. This is 100% correct, just did the test
Explanation: a pe x
The faster an object vibrates, the higher is the frequency and higher will be the pitch of the sound. During a flight approaching the speed of sound More drag is created because the air molecules are not moving out of the way of the airplane. The correct option is A.
What is sound?The sound is defined as a vibration which propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. The speed of a sound wave is affected by the medium through which it travels. Sound travels fastest in solids.
In aerodynamics, drag refers to the forces that oppose the relative motion of an object through the air. Drag always opposes the motion of the object and in an aircraft is overcome by thrust. Drag is a rearward force caused by the disruption of airflow by wing.
So here when a flight is approaching the speed of sound more drag is created.
Thus the correct option is A.
