If this is a true or false question this would be true
Answer:
About 3.5 kJ.
Explanation:
Recall the heat transfer equation:
Where <em>q</em> is the heat; <em>m</em> is the mass of the substance; <em>C</em> is its specific heat; and Δ<em>T</em> is the change in temperature.
The given specific heat of iron is 462 J/kg -°C.
Substitute and evaluate. Ensure correct units:
Therefore, the block of iron absorbed about 3.5 kJ of heat.
The earth probably would still be Pangaea form. All the continents would still be combined, and the earth would look very different.
Answer:
Prokaryotic cell
Explanation:
If you search it up you will see that the prokaryotic cell looks exactly alike with the picture you have posted.
The answer would be B.
Why?
Because compounds are a combination of two or more elements, while a mixture can be virtually anything. We cannot simply mix hydroxide and sodium together and claim it as a physical bond, it doesn't make sense since they react with each other in some way. However, mixtures are typically physical, since a chemical change most likely would not occur if we mixed popcorn and pretzels together in a bowl to make chex mix.
I hope I could help and I hope this made sense!
