Answer:
liquid
Explanation:
In the given context, the sample as collected by Carmen is clear and the sample has a sour smell. It is also mentioned that the sample is thick sample and when the sample is poured on a surface it begins to flow.
Such a sample would be a liquid sample because anything that flows is a liquid. The liquid sample has a high viscosity since it is thick.
Answer:liquid
Explanation:
Because it flows

1. A sample of oxygen (0.) gas has a mass of 32.65 g and a volume of 24.924 L. What is the density of the 0,gas?
Answer:
The answer is
1.31 g/LExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass of oxygen gas = 32.65 g
volume = 24.924 L
The density of the gas is
[tex]density = \frac{32.65}{24.924} \\ = 1.3099823463...[/tex]
We have the final answer as
1.31 g/LHope this helps you

what happened to the color of the sand when it goes through filtration and is quantitative or qualitative
Answer:
Qualitative
Explanation:
I'm not sure if there was another part to the question, but if you are looking at the color of the sand, that is a qualitative observation.
Quantitative statements involve numbers. (Ex: The house has 4 bedrooms.) Qualitative statements describe characteristics. (Ex: The house is blue.)List the two factors used to calculate force ? (20 pionts)
Answer:The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other.

Which of the examples represent potential energy A candy bar Wind A stretched rubber band Rowing a boat A ball rollinv down a hill A roller coaster at the top of a hill
Answer:
A candy bar
A stretched rubber band
A roller coaster at the top of a hill
Explanation:
Potential energy is the energy present as a result of the position of an object. This energy depicts zero motion or movement unlike kinetic energy.
A candy bar, stretched rubber band and roller coaster at the top of a hill all indicate positions without any said explanation of movement.
The other option choices depicts a type of movement .This is why the three option choices are correct in this scenario.
The examples that represent potential energy are:
A. A candy bar
B. A stretched rubber band
D. A roller coaster at the top of a hill
What is Potential energy?It is the stored energy in any object or system by virtue of its position or arrangement of parts. This energy depicts zero motion or movement unlike kinetic energy. For example : A candy bar, stretched rubber band and roller coaster at the top of a hill all indicate positions without any said explanation of movement.
Thus, correct options are A, B and D.

Explain how critical thinking helps scientists analyze information for accuracy and bias.
Answer:
Explain how critical thinking helps scientists analyze information for accuracy and bias.
Explanation:
Critical thinking requires scientists to ask questions about information they come across and assess its validity. This facet of critical thinking helps them avoid bias that originates from personal opinion and helps them distinguish information and fact from common belief.

Calculate the number of moles for 12.044*10^23 number of helium atoms
Answer:
Explanation:
number of moles=number of particle (atoms)/avogadro number (NA)
we know that avogadro number is equal to 6.23*10^23
given number of atoms=12.044*10^23
therefore
moles=12.044*10^23/6.23*10^23=1.9=2

Explanation:
The Arizona poppy has adapted to living in areas that receive less rain, but there are still periods of time that a drought occurs. What part(s) of photosynthesis would the plant not be able to perform if there were no rain? What would be the long-term effects on the plant if the drought continues? Explain your answer.
Answer:
When plants lose more water than they can take up from the soil, they become water stressed. ... Such drought conditions certainly inhibit the growth of plants. If it goes long enough without water it will die because the plant uses water for a lot of different jobs needed to keep the plant alive, so the long-term effect is that the plant will die if the drought continues.
Explanation:
The Arizona poppy is the summer herb of deserts of southwestern US and has pinnately compound leaves and large snowy flowers. This poppy appears in rainy seasons.
Due to the drought like conditions and fast-changing climate the poppy plant has learnt to adapt to the harsh climate of Arizona and is able to carry out the process of photosynthesis. In the case of long-term drought conditions, the process of photosynthesis slows down as plant will absorb more light. This leads to stunted growth and possible death of the plant.Learn more about the Arizona poppy that has adapted to living in areas that receive less rain.

The liquid state of matter can be described as
Answer:
The liquid state of matter is an intermediate phase between solid and gas. ... Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume. The limited amount of space between particles means that liquids have only very limited compressibility
Explanation:
A liquid is a nearly incompressible fluid with a nearly constant volume regardless of pressure that adapts to the shape of its container. It belongs to one of the four basic states of matter.
Volume retention and conformity to the shape of a liquid's container are two of its most noticeable physical characteristics. When a liquid substance is poured into a container, it conforms to the shape of the container and will stay inside the container so long as the liquid state persists.
The intermolecular forces of attraction in a liquid state of matter are stronger than those in a gaseous state but weaker than those in a solid state.

The density of manganese is 7.21 g/cm^3 . What is the density in kg/m^3 ? (dimensional analysis)
Answer:
7.21 x 103 kg/m3
Explanation:
Dimensional analysis has been the process to establish and convert the various units in the measurement. The density of manganese in kg/m3 is 7.21 × 10³ kg/m³.
What is dimensional analysis?Dimensional analysis has been the method that is also referred to as the unit factor or factor label method. It solves the mathematical expressions by multiplying the given value with another without changing its quantity and amount. It is used to change the units of the value.
Given,
Density of manganese = 7.21 g/cm³
The dimensional analysis method is used to convert grams per cubic centimeter into kilograms per cubic meter as:
1 gram / cubic centimeter = 1000 kilogram / cubic meter
So, 7.21 g/cm³ = X kilogram / cubic centimeter
Solving for X as:
X = 7.21 g/cm³ × 1000 kilogram / cubic centimeter
X = 7.21 × 10³ kg/m³
Therefore, 7.21 × 10³ kg/m³ is the density.
