Produces heat, putting off air or bubbles and changes the smell or odor it changes the state that’s how you know it is a chemical reaction
Answer:
this option is correct the amount of heat required to turn a mole of a solid into a liquid
P1V1T1=P2V2T2 Add 273 to convert degrees Celsius to Kelvin:
∴200×25/298=250×V2/273, ∴V2=200×25×273/298×250, ∴V2=18.32L
<h3>Where is the volume equation?</h3>
The basic formula for volume is length, breadth, and height, as opposed to length, width, and height for the area of a rectangular shape. The calculation is unaffected by how you refer to the various dimensions; for instance, you can use "depth" instead of "height."
<h3>What is chemistry using volume units?</h3>
Volume, which is measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface. The cubic meter (m3), a derived unit, is the SI unit of volume.

Answer:
Acetylide , Enol ,aldehydes, tautomers, alkynes , Hydroboration, Keto
Explanation:
Reset <u>Acetylide</u> anions are strong nucleophiles that open epoxide rings by an SN2 mechanism. <u>Enol </u>tautomers have an O-H group bonded to a C=C. <u>aldehydes </u>are formed from terminal alkynes with the addition of water using BH3 then H2O2. <u>tautomers</u> are constitutional isomers that differ in the location of a double bond and a hydrogen and exist in an equilibrium with each other. <u>alkynes</u> are compounds that contain a carbon-carbon triple bond. <u>Hydroboration</u> of a terminal alkyne adds BH₂ to the less substituted, terminal carbon.<u> Keto</u> tautomers have a C=O and an additional C-H bond.
Two or more different elements
