How many moles of acetaminophen are in a 0.8mL (0.0008L) dose of infants Tylenol
Answer:
0.007 mol
Explanation:
Step 1: Given data
Volume of acetaminophen: 0.8 mL
Step 2: Calculate the mass corresponding to 0.8 mL of acetaminophen
The density of acetaminophen is 1.26 g/mL.
0.8 mL × (1.26 g/mL) = 1 g
Step 3: Calculate the number of moles corresponding to 1 g of acetaminophen
The molar mass of acetaminophen is 151.16 g/mol.
1 g × (1 mol/151.16 g) = 0.007 mol

Josh is washing glasses with soap and water. He is afraid to carry the glasses because they are slippery. Josh could dry them with a towel to keep the glasses from being slippery.
What are glasses ?Glasses are visual eyewear that have lenses fixed in a frame that holds them in front of a person's eyes. The frame often has a bridge over the nose and arms that rest over the ears. Glasses are also known as eyeglasses or spectacles.
The term "glasses" likely originated from the word "spyglass," which was originally used to describe "a pair of eyeglasses" that had to be held up to the eyes in order to be fully effective.
Eyeglasses, often known as glasses or spectacles, are lenses that are mounted in frames and worn in front of the eyes to improve vision or to correct astigmatism, myopia, or hyperopia.
Thus, Josh could dry them with a towel to keep the glasses from being slippery.

what is the half life of the element in the picture
HELP BRAINLIEST
Answer:
6 days
Explanation:
The following data were obtained from the question:
Original amount (N₀) = 100 mg
Amount remaining (N) = 6. 25 mg
Time (t) = 24 days
Half life (t½) =?
Next, we shall determine the decay constant. This can be obtained as follow:
Original amount (N₀) = 100 mg
Amount remaining (N) = 6. 25 mg
Time (t) = 24 days
Decay constant (K) =?
Log (N₀/N) = kt / 2.303
Log (100/6.25) = k × 24 / 2.303
Log 16 = k × 24 / 2.303
1.2041 = k × 24 / 2.303
Cross multiply
k × 24 = 1.2041 × 2.303
Divide both side by 24
K = (1.2041 × 2.303) / 24
K = 0.1155 /day
Finally, we shall determine the half-life of the isotope as follow:
Decay constant (K) = 0.1155 /day
Half life (t½) =?
t½ = 0.693 / K
t½ = 0.693 / 0.1155
t½ = 6 days
Therefore, the half-life of the isotope is 6 days

Is it OK for people to post fake vacation pics and other fake info on social media? Why or why not? Use facts and details from the Article to back up your answer.
Answer:
No, It is not okay to pretend on social media.
Explanation:
No, it is not okay for people to post fake vacation pics and other fake info on social media. This is very wrong, as -
This 'all time look good, feel good, have a happening life' approach of social media - implies showing only the positive side & not negative side of people's life. However, in real life is not a bed of roses. Faking things out implies that pretending to be cool has become more important than sharing deep meaningful relationships, & highlights superficial desire of false popularity. It is also harmful to people being communicated this fake image, as they might indulge into any social involvement, on the basis of unreal image of the concerned person.Answer:
it is not ok because there are other people that will look at those pictures and say aww i wish i were them but we all need to exept who we are

How do the alveoli in the lungs move oxygen and nutrients into the bloodstream? 1.Gravity 4.Time 2.Diffusion 5.Pressure 3.Magnetic force
Answer:
2.Diffusion
Explanation:
As we metabolize certain nutrients for the correct functioning of our cells, carbon dioxide is produced as a result. We need oxygen in order to metabolize them, so we need to have a system to incorporate it, and to eliminate the carbon dioxide produced.
This system is provided by the interaction between the respiratory system, which allows the enter of oxygen into the body and gets rid of the carbon dioxide, and the circulatory system, which acts transporting carbon dioxide and oxygen to and from the lungs, respectively.
The surface available for the gaseous exchange is enlarged by the pulmonary alveoli. The alveoli are the terminal aerial spaces of the respiratory system and the structures where the exchange between the air and blood is produced. Each alveolus is surrounded by a net of capillaries, where oxygen is freed from the hemoglobin and moves into the cells by diffusion. Carbon dioxide, diffuses out of the cells into the capillaries, where most of it dissolves in the plasma of the blood.

An atom is made up of a nucleus and revolving electrons. Inside the nucleus protons and neutrons are located. Thus the components of an atom are protons, electrons and neutrons. Thus, option A is correct.
What is an atom?An atom is the basic unit of every substances. Atoms combine together to form molecules, molecules then forms compounds and so on.
The inner core of an atom is called nucleus which contains positively charged particles namely protons and neutral particles neutrons. There are circular paths of fixed energy surrounding the nucleus.
The circular paths around the nucleus is called orbits through which the electrons are revolving. Electrons are negatively charged particles and they neutralize equal number of positive charges.
A neutral atom have equal number of protons and electrons and this number is called its atomic number. The sum of number of protons and neutrons is called the mass number.
Hence, an atom is made up of protons, electrons, and neutrons and option A is correct.

Which statement is true about a rock layer deposited on top of another rock layer?
A- It is younger than the rock layer below.
B- It is older than the rock layer below.
C- It is the same age as the rock layer below.
D- It is no different than the rock layer below
Hello there!
Your answer is C.
Answer:
The right option is; A. It is younger than the rock layer below.
Explanation:
A rock layer deposited on top of another rock layer is younger than the rock layer below. This is based on the law of superposition which states that in any undeformed sequence of rocks that are laid down in layers, the youngest layer of rock will be on top of the sequence, while the oldest layer will be at the bottom of the sequence.

Answer & Explanation:
Susana's red crystal sample is a compound because it was broken down into a gas and blue powder. It is not an element because elements cannot be broken down into simpler substances by ordinary means, such as heating.

In each case, state whether the forces are balanced or unbalanced. If unbalanced, calculate the net force and describe the direction of the resultant force.
Answer:
Check explanation section.
Explanation:
In order to understand balanced force and unbalanced forces the first law of Newton should be considered as a basic knowledge.
For Balanced forces, there is equal equality in the direction of the forces. In balanced forces, there is no acceleration.
For unbalanced forces, there is acceleration that is go say there is going to be movement. Therefore, net force is equal to unbalanced forces.
(i) Suitcase dropped from a height.
Answer: since there is movement that is acceleration, then the force here is unbalanced force. The resultant force is downwards.towards the greater force direction.
(ii) A bicycle moving with constant velocity on a straight road.
Answer: As the bicycle moves at constant velocity on the straight road the force here is Balanced. Frictional forces balances the forces from the cyclist.
(iii) The rope does not move in a tug of war on applying force at both ends.
