Answer:The Law of Conservation of Mass simply states that the total amount of mass should not change in a chemical reaction that is isolated (no other objects can enter the reaction). The total mass of the reactants must be equal to the total mass of the products. Thus, the correct estimate of the amount of oxygen used in the interaction is the difference between 133 g and 29 g.

Need this asap ill mark brainliest On the Internet, many authors post opinion articles on scientific topics. What are the benefits and drawbacks of these opinion articles in regard to scientific discussion?
Answer:
A benefit of the opinion of a scientific author is that you can see others points of view on a subject. A drawback is that they are using an opinion and most likely not stating unbiased facts.

Answer:
Highlights:
*Researchers in the sciences do not see access to the scientific literature as an especially important problem.
*Authors consider factors such as journal reputation and the absence of publication fees when deciding where to submit their work. In contrast, free access is not a significant factor in their submission decisions.
Implications:
*While open access has the potential to expand the authorship and readership of the scientific literature, that potential has not yet been realized.
*Librarians who encourage scientists to publish in open access journals should be aware of the authors' priorities and perspectives. Authors in the sciences tend to focus on citation impact, reputation, and accessibility to a specialized readership—not breadth of readership, copyright, or access status.
*Journal publishers that charge publication fees may want to consider alternative sources of revenue. Authors' resistance to publication fees is a major barrier to greater participation in open access initiatives.

Explanation:
What is convection?
a Transfer of heat through objects touching the source
b Transfer of heat through direct physical contact
c Transfer of heat through electromagnetic waves
d Transfer of heat through the movement of particles
Answer:
d transfer of heat through the movement of particles
The correct answer is option d: Transfer of heat through the movement of particles. Convection is a mode of heat transfer that occurs through the movement of particles.
Convection is the transfer of heat through the movement of particles in a fluid, such as a gas or liquid. Option (d) is the correct answer. Convection occurs when a temperature difference exists within the fluid, causing the hotter particles to become less dense and rise while the cooler particles sink. This movement creates a circulation pattern known as convection currents. Convection is a significant mechanism for heat transfer in various natural and man-made systems. For example, when a pot of water is heated on a stove, the bottom of the pot gets hot, causing the water near the bottom to heat up and expand. This hot water rises to the top, transferring heat to the surrounding cooler water. As a result, the water circulates in a convection current, leading to a more uniform distribution of heat. Convection is also responsible for phenomena like ocean currents, atmospheric circulation, and even the formation of thunderstorms. It plays a crucial role in distributing heat within the Earth's atmosphere and oceans, impacting weather patterns and climate.

What type of spectrum is produced when electromagnetic radiation is emitted or absorbed as electrons change energy levels in an atom?
The type of spectrum is produced when electromagnetic radiation is emitted or absorbed as electrons change energy levels in an atom is hydrogen spectrum.
What is hydrogen spectrum?The hydrogen spectrum is given by the scientist Bohr and it consist of series name lyman, balmer, paschen, bracklet and p- fund as the electromagnetic radiations splits into this.
The lyman series is formed when electrons jumps from any hige energy level to n = 1 and will be same for balmer , pachen ,bracklet and p-fund are obtained when electrons jumps from any higher energy level to n = 2,3,4 and 5 respectively.
Therefore, type of spectrum is produced when electromagnetic radiation is emitted or absorbed as electrons change energy levels in an atom is hydrogen spectrum.

The diagram shows a generator powered by a water turbine. Based on the diagram, what type of energy transformation takes place in the generator?
A
Mechanical energy is transformed into electrical energy.
B
Chemical energy is transformed into kinetic energy.
C
Electrical energy is transformed into potential energy.
D
Electrical energy is transformed into chemical energy.
The transformation takes place in the generator is mechanical energy is transformed into electrical energy. Hence option A is correct.
What is energy transformation?Energy transformation is defined as the conversion of energy from one form to another. The passage of energy from one place to another is known as energy transfer. When energy transforms, it goes from one type to another.
Hydroelectricity is a type of renewable energy that produces electricity by harnessing the force of moving water. Mechanical energy is transformed into electrical energy in a generator. Most generators create alternating current as their source of electricity. A generator spins when a turbine's blades rotate due to falling water, converting the mechanical energy of the spinning turbine into electrical energy.
Thus, the transformation takes place in the generator is mechanical energy is transformed into electrical energy. Hence option A is correct.

The amplitude of a wave is related to the energy of a wave. Did you see anything on the screen that made you think this or could prove your point? How could you demonstrate this relationship?
Answer:The higher the amplitude, the higher the energy. To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.
Explanation:
The amplitude of a wave is directly related to the energy of a wave.
What is amplitude?Amplitude is the maximum distance covered by a body from the main point in the vibrating mode.
As we know that energy of the wave is directly proportional to the square of the amplitude:
E ∝ (a)²
As the amplitude of wave increases, energy carried by the wave is also increases. Higher energy increases the amplitude of the propagating wave.

Whats the effect of this?
A wave enters a medium where its wave speed is slower.
Answer:
Wave speed, frequency and wavelength in refraction
Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.

Answer:
Waves. Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. Light is refracted when it crosses the interface from air into glass in which it moves more slowly.
