The BEST way of disposing of used oil, which is not biodegradable, is to take it to the local automotive parts store to be recycled.
Disposing of used oil properly is crucial to prevent environmental pollution. Pouring it down the drain is not recommended as it can contaminate water sources and harm aquatic life. Using it to paint a wooden fence is not an appropriate method of disposal and may result in environmental damage.
Instead, the preferred approach is to take it to a local automotive parts store that offers oil recycling services. These stores have the necessary facilities to handle and recycle used oil responsibly. By doing so, we can contribute to reducing waste and minimizing the impact on the environment.

Relate two factors that can limit the accuracy and precision of measurements.
Temperature, humidity, pressure, gravity, altitude, vibration, stress, strain, and illumination are among the variables.
What are precision and accuracy?
Accuracy is the capacity of an instrument to measure the precise value. In other words, it refers to how closely the measured value resembles a reference or genuine value. Small readings can be taken to increase accuracy. The calculation's inaccuracy is decreased by the little reading.
The precision of a material is defined as the degree to which two or more measurements agree with one another. It is incredibly precise but not always accurate to measure something if you weigh it five times and get 3.2 kg each time. Accuracy is not necessary for precision.
The degree to which a measurement is accurate in relation to its real value. The degree to which the same results are produced by repeated measurements under the same circumstances is known as precision.
Therefore, temperature, humidity, pressure, gravity, altitude, vibration, stress, strain, and illumination are among the variables.

What happens to the atoms that make up hydrogen fuel as it burns?
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

The law of conservation of matter states that matter can be neither created nor destroyed. Your friend shows you the following chemical equation: CaCO3,CaO+CO2, He says that because the oxygen atoms are split between two different molecules in the products, the equation does not support the law of conservation of matter. Is your friend right? Explain your answer.
Answer:
no
Explanation:
no your friend is not right, everything is supported by the law of conservation of matter, just because the oxygen atoms are split doesn't mean it isn't supported by this

Which statement best describes how energy is important to chemistry?
A. Energy is stored in an atom's electrons.
B. Energy is not conserved during chemical reactions,
C. Energy is absorbed and released during chemical reactions,
D. Energy holds atoms and bonds together,
Answer:
C. Energy is absorbed and released during chemical reactions,
Explanation:
All chemical reactions involve energy. Energy is used to break bonds in reactants, and energy is released when new bonds form in products. Endothermic reactions absorb energy, and exothermic reactions release energy.
In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

The word planet comes from the Greek word planetai, which means wanderer because the ancient Greeks thought of the planets as wandering through the stars.
True
False
btw this is a science question
Answer: True
Explanation:
Asteres planetoid, or 'wandering stars,' was the term used by Greek astronomers to describe star-like objects that appeared to move across the sky.
The term has been applied to a wide range of objects, including the moon, satellites, the sun, and asteroids.
A planet, according to the International Astronomical Union (IAU), is a body that orbits the Sun, is massive enough for its own gravity to keep it around, and has 'cleared its neighborhood' of smaller objects approaching its orbit.
