6. Model conservation of mass in a labeled drawing that illustrates a physical change.
Answers
Answer:
hope it's help you
Explanation:
In an isolated system, neither chemical processes nor physical changes can create or destroy mass, according to the principle of mass conservation. According to the law of conservation of mass, the mass of the products and reactants of a chemical reaction must be equal.
Why is mass conservation crucial?According to the law of conservation of mass, matter cannot be created or destroyed in a chemical reaction. When wood burns, for example, the mass of the soot, ashes, and gases equals the original mass of the charcoal and oxygen when it first reacted. As a result, the product's mass equals the reactant's mass. The understanding that substances do not, contrary to appearances, vanish as a result of a reaction, but rather change into another material of equal mass, was made possible by the law of conservation of mass, which was essential to the development of chemistry. The law of conservation of mass does not always apply.To learn more about mass conservation refer to:

how many sodium atoms are present in 0.2310 g of sodium?
Answers
Answer:
There are 6.048X10^21 atoms present in 0.2310 g of sodium.
Explanation:
We know,
23g Na contains 6.022X10^23 atoms
∴1g Na contains 6.022X10^23/23 atoms
So, 0.2310g Na contains (6.022X10^23/23)X0.2310 atoms
= 6.048X10^21 atoms
There are 6.048X10^21 atoms present in 0.2310 g of sodium.
The number of atoms present in 0.231 g of sodium is 6.02 x 10²¹ atoms.
The given parameters;
mass of the reacting sodium = 0.231 g1 mole of an atom = 6.02 x 10²³ atomsthe atomic mass of sodium is 23 g/molThe number of moles of 0.231 g of sodium available is calculated as;
[tex]no. \ of \ moles = \frac{Reacting \ mass}{Molar \ mass} \\\\no. \ of \ moles = \frac{0.231}{23} \\\\no. \ of \ moles = 0.01 \ mol.[/tex]
The number of atoms of 0.01 mole of sodium available is calculated as;
1 mole ---------- 6.02 x 10²³ atoms
0.01 ----------------- ?
= 0.01 x 6.02 x 10²³ atoms
= 6.02 x 10²¹ atoms.
Thus, the number of atoms present in 0.231 g of sodium is 6.02 x 10²¹ atoms.

For most of the first 1,800 years in the common era, most people, including scholars, did not believe in sexual or asexual reproduction for many organisms. They thought many creatures, including frogs and mice, came from nonliving things. This was the theory of spontaneous generation. For example, maggots were believed to simply appear in meat as it spoiled. Today we know that maggots come from eggs that were laid on or in the meat by their mothers.
Louis Pasteur proved that living organisms do not just appear. Broth that is left sitting out for a while will grow cloudy as small organisms live and grow in it. Louis Pasteur boiled broth and let it cool without coming into contact with any "particles" in the air. Broth treated that way did not grow cloudy.
Louis Pasteur's experiment showed that small organisms that live in broth do not come from the broth itself. Which of the following best describes this statement and how it changed what scientists know?
A.
It is a scientific theory of how life begins that fits the facts better than spontaneous generation.
B.
It is a scientific observation that goes against the theory of spontaneous generation, so the theory must be wrong.
C.
It is a set of detailed observations of how single-celled organisms live and reproduce.
D.
It is a result that was predicted by the theory of sexual reproduction, proving that theory to be correct.
Answers
Answer:
the answer is option b
Explanation:
he conducted an experiment and the observation was against what the theory had said
The statement best described in the passage is: It is a scientific observation that goes against the theory of spontaneous generation, so the theory must be wrong. Option B is correct.
The passage describes Louis Pasteur's experiment, which refuted the prevailing theory of spontaneous generation. The theory of spontaneous generation suggested that certain organisms could arise from nonliving matter, such as maggots spontaneously appearing in spoiled meat.
However, Louis Pasteur's experiment demonstrated that living organisms do not simply appear but come from pre-existing living organisms. By showing that broth treated in a specific way did not grow cloudy with small organisms, Pasteur provided evidence against spontaneous generation, leading to the rejection of that theory.
This scientific observation changed what scientists know by disproving the long-held belief in spontaneous generation and providing evidence to support the idea of biogenesis, where living organisms arise from other living organisms. This experiment laid the foundation for our modern understanding of the origin of life and the importance of studying the role of microorganisms in various biological processes.
Hence, B. is the correct option.

Why do you have to have a certain number of reactants on one side?
Answers
Answer:Because you need that certain number and double the number of bread to get the reactants off of the sides
Explanation: 4 bread reactants- 2meat reactants- 2 cheese reactants= 2 products
The reason for the presence of a certain number of reactants on one side is to ensure that the chemical equation is balanced.
In a balanced chemical equation, the number of atoms of each element on the reactant side must be equal to the number of atoms of that element on the product side.
Consider the equation:
[tex]2H_2 + O_2 - > 2H_2O.[/tex]
This equation represents the reaction of hydrogen gas ([tex]H_2[/tex]) with oxygen gas ([tex]O_2[/tex]) to form water ([tex]H_2O[/tex]).
To balance this equation, double the coefficient in front of [tex]H_2O[/tex] on the product side, resulting in 4 hydrogen atoms and 2 oxygen atoms on both sides.
Therefore, having a certain number of reactants on one side is necessary to ensure that a chemical equation is balanced, satisfying the law of conservation of mass.

SpongeBob loves to garden and wants to grow lots of pink flowers for his pal Sandy. He brought a special Flower Power fertilizer to see if it will help plants produce more flowers. He plants two plants of the same size in separate containers with the same amount of potting soil. He places one plant in a sunny window and waters it every day with fertilized water. He places the other plant on a shelf in a closet and waters it with plain water every other day.
What did SpongeBob do wrong in this experiment? Explain.
How could SpongeBob improve his experiment?
Answers
Answer: He had more than one independent variable.
Explanation: It would only be fair, if both plants were in a sunny window, because then, it would be easier to see if the fertilizer actually affected the plants. This is because there is always a chance that the lack of sunlight decreased the number of flowers on the plant, instead of the fertilizer. It is always better to just have one independent variable.

what's going to be in the he World
Answers
Answer:
Lots of people set the alarm with the best of intentions, knowing that's the time they need to get up to meet the day's demands. But then the alarm clock seems to ring way before they're ready to rise, so they're hitting snooze and, eventually, running late. Something's got to give.
The key lies inside your body. "An important factor in being able to wake up easily at the desired time in the morning is the timing of one's circadian rhythm, or 'body clock,'" says sleep researcher Leon C. Lack, PhD, professor emeritus in the school of psychology at Flinders University in Adelaide, Australia. Much of what you need to do to wake up on time starts by planning your sleep schedule the day and the evening before — and by making your mornings count.
How do our internal clocks work, and how much can we control them? According to the National Institutes of General Medical Sciences (NIGMS), the body’s master clock, located in the brain, produces and regulates our circadian rhythms, which help determine sleep patterns over the course of a 24 hour period. Environmental signals, such as daylight and darkness, affect circadian rhythms, too. When incoming light hits the optic nerves, information is passed along from the eyes to the brain. When there is little or no light — at night — your clock tells the brain to make more melatonin, a hormone which makes you sleepy.
Our sleep-wake cycles, hormone levels, metabolism, and body temperature are all affected by our circadian rhythms, notes the National Institute of Neurological Disorders and Stroke. When your rhythm is off, you may be at risk for more than just a few groggy days you drag yourself through. Irregular rhythms, the NIGMS notes, have been linked to chronic health conditions, such as obesity, diabetes, depression, bipolar disorder, and seasonal affective disorder.
But there are ways to recalibrate your system to get the sleep you need and wake up feeling refreshed and ready for the day ahead. Physiological and psychological factors come into play, and it’s not always easy to get a good night’s rest or adhere to a schedule so that you consistently go to sleep and get up around the same time each day.
