Hello,
Here is your answer:
The proper answer to this question is option D "wood is burned". Its a chemical change because its changing forms wood to ash.
Your answer is D.
If you need anymore help feel free to ask me!
Hope this helps!
The earth is often referred as a blue planet because the hydrosphere looks blue and it covers 3/4 of the earths surface. So the answer is D
The molecular formula of styrene is B) C8H8.
Styrene is an organic compound with a chemical formula of C6H5CH=CH<span>2</span>
Confirmation bias<span>, also called </span>confirmatory bias<span> or </span>myside bias, is the tendency to search for, interpret, favor, and recall information in a way that confirms one's preexisting beliefs or hypotheses, while giving disproportionately less consideration to alternative possibilities.[Note 1][1]<span> It is a type of </span>cognitive bias<span> and a systematic error of </span>inductive reasoning<span>. People display this bias when they gather or remember information selectively, or when they interpret it in a </span>biased way<span>. The effect is stronger for </span>emotionally<span> charged issues and for deeply entrenched beliefs. People also tend to interpret ambiguous </span>evidence<span> as supporting their existing position. Biased search, interpretation and memory have been invoked to explain </span>attitude polarization<span> (when a disagreement becomes more extreme even though the different parties are exposed to the same evidence), </span>belief perseverance<span> (when beliefs persist after the evidence for them is shown to be false), the irrational primacy effect (a greater reliance on information encountered early in a series) and </span>illusory correlation<span> (when people falsely perceive an association between two events or situations).</span>
1.the chemical change color from colorless to purple
2. A yellow gas forms
3.a brown solid forms in the bottom of the beaker
4.the temperature of the chemicals rises 15 Celsius
Explanation:
All of the options are proofs that chemical change has occurred.
A chemical change is one with the following properties:
- A new kind of matter is usually formed as seen by the gas evolution and the formation of the insoluble precipitate i.e brown solid at the bottom of the beaker.
- They are not easily reversible.
- Usually accompanied by energy changes as seen in the rise in temperature.
- Color changes can also infer chemical changes in a reaction.
