If there is some reason you cannot get the compound from a natural source, it may be helpful to use a synthetic, yet identical, version. If harvesting the item from nature is too expensive or over-harvesting could damage the environment or destroy habitat, it might be better to synthesize the compound.

Find the empirical and the molecular formula of acetylene gas composed of 92.26 percent carbon and 7.74 percent hydrogen

Hitman42 [59]

Answer:

Explanation:

92.26% = 92.26 g

7.74% = 7.74 g

carbon is 92.26 x 1 mole/12.011 = 7.68

hydrogen is 7.74 x 1 mole/1.008 = 7.68

carbon 7.68 ÷ hydrogen 7.68 = 1

so 1 is your subscript for both carbon and hydrogen

Draw the product you expect from the reaction of (s)-3-iodohexane with ch3co2-. be sure to show stereochemistry.

Rasek [7]

This will give substituted product which will be by SN2 mechanism

so here we will get product with inverted geometry

In SN2 mechanism the nucleophile attacks from back side and we always get product with inverted geometry

This is known as Walden inversion.

Chemical equation for heat of formation of c25h52

Alexus [3.1K]

its exothermic. exothermic means the reaction gives out heat. [exo meaning outside and thermic meaning heat] because its a combustion reaction, fire is there meaning lots of heat.
endothermic means it takes in heat. a good example is ammonium and water (NH3 +H20)
<span>most chemical reaction are exothermic</span>
