Matter is anything that takes up space and can be described by physical and chemical properties. Which statement
BEST differentiates chemical properties from physical properties?
A)
Physical properties are properties that can be physically seen or touched,
while chemical properties can only be found when matter is mixed with
specific chemicals.
B)
Physical properties are measured when matter changes its physical state,
while chemical properties can only be measured if matter remains in one
state for an extended time.
C)
Physical properties are difficult to measure because they require special
tools to detect, and chemical properties are easy to measure and require
not special tools to detect.
D)
Physical properties can be measured/observed without changing matter
into something else, while chemical properties describe matter's ability to
react/combine with other matter.

Answer:

D)

Physical properties can be measured/observed without changing matter

into something else, while chemical properties describe matter's ability to

react/combine with other matter.

Explanation:

Physical Change                                                                                              

The changes that occur only due to change in shape or physical properties but their chemical or internal composition remain unchanged.  

1 = These changes were reversible.

2= They have same chemical property.

3= These changes can be observed with naked eye.

Example :

Water converting to Ice

Water converting to gas

In this water molecule remain the same only they rearrange themselves that change its state of mater not composition

Chemical change:

The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.

1 = These changes are irreversible

2 = These changes occur due to chemical reactions

3 = These may not be observed with naked eye

Example:

Combustion of fuel or wood: that oil or wood convert into energy, CO₂ and ash in case of wood

Boiling of egg: that change the chemical composition of protein in the egg .

The reaction of Hydrogen and oxygen:

H₂ (g)  + O₂  (g)   →    2H₂O  (l)

A sample of gas has a volume of 10 ml at 2 atm. The pressure increases to 4 atm. What is the new volume?

Answers

Answer:

The answer is 5 mL

Explanation:

In order to find the new volume we use the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we are finding the new volume

[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]

We have

[tex]V_2 = \frac{10 \times 2}{4} = \frac{20}{4} \\ [/tex]

We have the final answer as

5 mL

1Which statement about plant cells is true? A A plant cell cannot contain both a nucleus and chlorophyll. Incorrect answer B A plant cell can contain both chlorophyll and a nucleus. Incorrect answer C A plant cell must contain chlorophyll, but can have no nucleus. Incorrect answer D A plant cell has neither a nucleus nor chlorophyll.

Answers

Answer:

B A plant cell can contain both chlorophyll and a nucleus.

Explanation:

All plants are eukaryotic organisms i.e the cells of all plants possess a membrane-bound nucleus that houses their genetic material (DNA). In addition to this, most plant cells also contain a unique organelle called CHLOROPLAST, which they use to capture the energy from sunlight in order to perform a process called PHOTOSYNTHESIS.

According to this question, plant cells can contain both chlorophyll and a nucleus. They can possess chlorophyll because chlorophyll is a pigment in their chloroplast that captures the light energy.

A woman is found dead on a boat floating in the middle of a lake at 4:30am. There is blunt force trauma to her head but no other discernable damage. She is approximately 30 pounds overweight. She is wearing thermal clothing and a winter jacket, gloves, and hat. Climatological data indicate it was a clear, cold, and windy night with no precipitation. Calculate the time of death based only on a body temperature of 15.6°C (60.8°F)? Now consider the other factors presented. How would each affect this estimation?

Answers

Answer:

Dead bodies lose one degree Celsius per hour, which we could deduce that the person died 12 hours ago.

Explanation:

On the other hand, it is very important to take into account that this number of hours is very approximate, since not only does it vary greatly with the environment and the acclimatization of the environment in which the person dies, but also in this specific case, insulating clothing was presented , which made the loss of body heat much more difficult and could easily be more than 12 hours.

The minimum for this particular situation is 12 hours to 24 hours possible postmortem.

When copper is bombarded with high-energy electrons, X rays are emitted. Calculate the energy (in joules) associated with the photons if the wavelength of the X rays is 0.154 nm.

Answers

Answer:

E = 12.92 × 10^(-16) J

Explanation:

Formula for energy is;

E = hc/λ

Where;

h is Planck's constant = 6.63 x 10^(-34) J.s

c is speed of light = 3 × 10^(8) m/s

λ is wavelength = 0.154 nm = 0.154 × 10^(-9) m

E = (6.63 x 10^(-34) × 3 × 10^(8))/(0.154 × 10^(-9))

E = 12.92 × 10^(-16) J

The energy associated with the photons of X rays with a wavelength of 0.154 nm is 1.29 × 10⁻¹⁵ J.

When copper is bombarded with high-energy electrons, X rays, with a wavelength of 0.154 nm (λ) are emitted.

We can calculate the energy (E) associated with the photons of these X rays using the Planck-Einstein relation.

[tex]E = \frac{h \times c }{\lambda } = \frac{(6.63 \times 10^{-34}J.s ) \times (3.00 \times 10^{8}m/s ) }{0.154 \times 10^{-9} m } ]= 1.29 \times 10^{-15} J[/tex]

where,

h: Planck's constantc: speed of light

The energy associated with the photons of X rays with a wavelength of 0.154 nm is 1.29 × 10⁻¹⁵ J.

He cant have my shoes, he stole my guitar! Erkans eyes looked impudent beneath his dark brow as his cheeks reddened in fury. His gray-whiskered lips trembled as his hand gripped tightly around the nurses wrist. The nurse carefully but firmly freed himself from Erkans grasp. He then turned to the caregiver who was assisting him, smiled, and said calmly, Go get Michelle.Michelle was scanning boxes of gauze bandages and stacking them onto a shelf in the storeroom when the caregiver came in and announced, Phillips trying to get Erkan to take a shower and he needs your help. Michelle rushed out of the store room and down the hall to Erkans room.This was the last week of Michelles internship. It was her junior year, and the internship was part of her Workplace and Consumer Education class. At first she wanted to intern at her dads gas station, but her teacher told her she needed to branch out and signed Michelle up at the Oakcourt Nursing Home, only 15 minutes away from her house.Wearing a Pittsburgh Steelers sweatshirt and jeans, with dark curls pushed back in a hair clip, Michelle stood out from the crowd of nurses and caregivers in white pants and polo shirts who were standing huddled in the doorway of Erkans room. She moved past them and rushed to Erkans side. As soon as he saw her, Erkans face brightened and he stopped looking like a stricken animal and instead looked like someone who recognized a dear old friend.He cant have them, Michelle. I sold them at the corner, Erkan shouted, pushing his way to Michelle. He stole my guitar, he whispered.I know, Erkan, but he was only trying to help you get some money to pay for your trip. Michelle had been frightened by a lot of the residents of the nursing home when she first started the beginning of the semester. Many of them were incoherent and loud, and some could be very aggressive and scary. Erkan often pushed or kicked and ranted. Michelle had started to regret this internship, and she even avoided going near Erkans room whenever possible. He lives in his own world, Philip, the managing nurse, explained to Michelle after her first encounter with Erkans temper.Still, Michelle had been curious, and she felt sorry that Erkan had a bad reputation among the staff. She too had felt like everyone mistrusted herespecially at the nursing home where she was so much younger than the rest of the staffso she understood how he must feel. Besides, he was the only person in the whole place with skin nearly as dark as hers.Over time, she noticed patterns in Erkans rants: He would sometimes mention his guitar and his father and the city of Diyarbakir, which she learned is in Turkey. So she decided that the next time she brought supplies to his room, instead of avoiding Erkan, she would play along with whatever he said. If he lived in his own world, then she would try to join him there. Bit by bit, she discovered that he had immigrated to the United States from Turkey when he was very young. His father had saved as much money as possible to pay for his journey, but he needed to sell Erkans guitar to help cover the cost. Erkan had moved in with his aunts family in Scranton, Pennsylvania, and finished school there. Eventually he got married, had children of his own, and worked for years signing Turkish singers to a small record label. But hed never quite felt at home in the United States.I know he sold your guitar, but you told me yourself he just wants whats best for you, Michelle said, while Philip and the caregiver looked on in amazement as Erkan settled into an armchair. Now why dont you listen to Philip, take your shoes off, and have a shower?For you, Michelle, Ill do it.You can feel out of place in a country, in the place where you live, or even in your own head, Michelle thought. But if youre lucky, someone will know how to find you and remind you that we all feel that way sometimes.In Out of Place, how has Ekrans relationship with Michelle affected him?
