CH3OCH3 (ether) will dissolve in water because
dangina [55]

Answer:

a. polar solutes dissolve in polar solvents.

Explanation:

Polarity is a phenomenon that has to do with the positive and negative electric (ionic) charges of a molecule. A molecule with distinct positive and electric charge is said to be POLAR. However, water is said to be a universal solvent because it dissolves more substances than any other solvent can.

This solvent property of water is a function of its POLARITY. Polar solutes dissolve in polar solvents. Hence, only polar solutes can dissolve in water (a polar solvent). Hence, in this case, CH3OCH3 (ether) will dissolve in water because it is a POLAR molecule/solute.

Classify the compound below as an alkane, alkene, alkyne, alcohol, aldehyde, amine, and so forth
Gnoma [55]

<em>Answer:</em>

  • Organic compounds are those which are derivatives of hydrocarbons. They are classified into following functional groups.

<em>Alkane:  </em>

  • Alkane are simplest hydrocarbons.
  • They have general formula CnH2n+2. These hydrocarbons contain single bond.
  • For example ethane , H3C----CH3.

<em>Alkene:</em>

  • Alkene are most reactive.
  • They have general formula CnH2n.
  • These contain double bond in their structure.
  • For example , ethene, H2C=CH2

<em>Alkyne:</em>

  • These are less less reactive as compare to alkenes.
  • They have general formula CnH2n-2.
  • They contain triple bonds in their structure.
  • For example Acetylene HC≡CH

<em>Alcohol:</em>

Alcohol have functional group OH. They have general formual R---OH, R may be alkyl group.For example Ethanol H3CH2C---OH

<em>Amine:</em>

  • Amine contain NH2 F.G.
  • They have general formula R---NH2.
  • There are three types of amine like primary, secondary and tertiary amine.
  • For example H3CH2C---NH2

<em>Aldehyde:</em>

  • Aldehydes have CHO F.G .
  • They have general formula R--CHO.
  • For example H3CH2C---CHO

<em>Ketone:</em>

  • Ketones have R--CO--R functional group.
  • For example acetone H3C---CO---CH3

<em>Carboxylic acid:</em>

  • They functional group COOH.
  • Their general formula is R---COOH.
  • For example Acetic acid H3C---COOH

How does yeast cause bread to rise?
lana66690 [7]

Answer/Explanation:

As bread is baked, the yeasts release carbon dioxide that causes the bread to rise. ... The yeast uses glycolysis and alcohol fermentation to break down sugars in the dough. The yeast releases alcohol and carbon dioxide as a waste product. The carbon dioxide gas causes the bread to rise.
