Answer:
honey has the highest viscosity
According to the given option, honey is the liquid that has the highest viscosity. So, the correct option is D.
What do you mean by Viscosity?Viscosity may be defined as the effects of a liquid by probity of which an internal resistance comes into play when the liquid is in movement and resists the comparable motion between its distinct layers.
Among all the given options, honey possesses more strong intermolecular attractive forces that result in the high compaction of particles in the honey.
After honey, Oil is more viscous followed by milk, and then water.
Therefore, the correct option for this question is D.

Answer:
20.03g
Explanation:
This is the formula for percentage yield:
Percentage yield = Actual Yield / Theoretical yield
Rearrange it to get the Actual yield, which would be:
Actual yield = Percentage yield (in decimal form) x Theoretical yield
We know that 75% of CO2 is produced as the percentage yield in a reaction and the theoretical yield for the mass we're supposed to find is 26.7 grams.
Percentage yield in decimal form: 0.75
Theoretical yield: 26.7g
Plug it in the equation
Actual yield = 0.75 x 26.7g
Actual yield = 20.03g

How many moles are there in 10 dm3 of sulfur dioxide gas
Taking into account the room temperature and pressure, there are 0.4167 moles in 10 dm³ of sulfur dioxide gas.
RTP refers to Room Temperature and Pressure. Pressure is 1 atm and Temperature is 298K. In this case, one mole of any gas has a volume of 24 dm³ or 24,000 cm³. This volume is called the molar volume of a gas.
In other words, the molar volume (the amount of space occupied by one mole) of any gas is 24dm³ (1 mol of gas molecules occupies 24.0 dm³).
Therefore, the amount of volume occupied by any gas can be calculated by multiplying the number of moles of gas by 24dm³:
Volume = Moles of gas× 24 dm³
So, the number of moles can be calculated as:
Moles of gas= Volume÷ 24 dm³
In this case, you know that volume if sulfur dioxide gas is 10 dm³. So, replacing:
Moles of gas= 10 dm³ ÷ 24 dm³
Solving:
Moles of gas= 0.4167
Finally, there are 0.4167 moles in 10 dm³ of sulfur dioxide gas.

What is an electron?
An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom) or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron.

noble gases are used in many situations where a safe and constant environment must be maintained. for example, helium is used to provide a protective atmosphere for making fiber optics and semiconductors. argon is used to fill incandescent and flourescent light bulbs to prevent oxygen from corroding the hot filament. why are noble gases used in these situations?
Answer:
Because they do not naturally react with other elements
Explanation:
Since noble gases do have a fulfilled valence shell, they do not react with other elements because they're already stable by the themselves.

Kelli and Jarvis are members of the stage crew for the Variety Show. Between acts, they must quickly move a Baby Grand Piano onto stage. After the curtain closes, they exert a sudden forward force of 524 N to budge the piano from rest and get it up to speed. The 158-kg piano experiences 418 N of friction. a. What is the piano's acceleration during this phase of its motion? b. If Kelli and Jarvis maintain this forward force for 1.44 seconds, then what speed will the piano have?
If Kelli and Jarvis maintain a forward force of 524 N for 1.44 seconds on a 158-kg piano, the acceleration will be 0.671 m/s² and the final velocity will be 0.966 m/s.
Kelli and Jarvis exert a force of 524 N on a 158- kg (m) piano.
The friction force, which opposes this force, is 418 N.
The net force (F) is the difference between both forces.
F = 524 N - 418 N = 106 N
We can calculate the acceleration (a) of the piano using Newton's second law of motion.
What is Newton's second law of motion?Newton's second law of motion states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force and inversely proportional to the mass of the object.
a = F/m = 106 N/158kg = 0.671 m/s²
The piano start from rest (u = 0 m/s) and moves with an acceleration of 0.671 m/s² for 1.44 s.
We can calculate its final velocity (v) using the following kinematic equation.
v = u + a × t
v = 0 m/s + 0.671 m/s² × 1.44 s = 0.966 m/s
If Kelli and Jarvis maintain a forward force of 524 N for 1.44 seconds on a 158-kg piano, the acceleration will be 0.671 m/s² and the final velocity will be 0.966 m/s.

Explanation:
According to the forces of attraction , for a substance to melt molecules in the substance gain kinetic energy and then become less tightly bound to each other.
What are forces of attraction?Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.
