Answer:
C. the solid dissolves after it is added to the liquid
Explanation:
Why, you may ask? Because endothermic reactions absorb energy by undergoing change. And that solid, just absorbed energy.
When something melts, the molecules inside the substance receive more and more energy, until the substance's molecules have enough energy to vibrate and wiggle past each other, breaking their structure. if the solid is receiving more energy from its surroundings, aka the liquid, the reaction is in fact absorbing energy. And if a reaction is absorbing energy, it's an endothermic reaction.
The force due to friction is generally independent of the contact area between the two surfaces. This implies regardless of whether you have two overwhelming objects of a similar mass, where one is half as long and twice as high as the other one, despite everything they experience the equivalent frictional power when you drag them over the ground.
Answer:
asexual reproduction
Explanation:
some multicellular organisms also reproduce by producing genetically identical clones of themselves. any form of reproduction that results in new individuals that are genetically identical is called asexual reproduction

An allylic carbocation is a reactive intermediate in the reaction of 1,3-diene with her, resulting in 1,4-addition.
<h3>What is
carbocation?</h3>
- A molecule called a carbocation has three bonds and a positively charged carbon atom.
- They are essentially carbon cations, to put it simply.
- It was once referred to as carbonium ion.
- Any even-electron cation with a sizable positive charge on the carbon atom is now referred to as a carbocation.
<h3>Why are carbohydrate molecules crucial?</h3>
- Because charge can be exchanged between many atoms when the vacant p orbital of a carbocation overlaps with the p orbitals of another carbon-carbon double or triple bond, carbocations next to other carbon-carbon double or triple bonds are very stable.
