Answer:

Explanation:

carbon in  group 4A needs 4 more electrons to be stable

hydrogen in group 1A has one electron needs 1 more t o be stale

oxygen in group 6A has 6 and needs 2 more to be stable

They all obtain this by sharing electrons  8 around C &O, 2 around H

H  : C:  H

       ::        

      :O:

What is the hydrophobic effect? what types of atoms are most likely to be found in portions of molecules or entire molecules tha
HACTEHA [7]
Hydrophobic in simple terms is the "fear" of water.

In chemistry, Ionic salts are technically hydrophilic as they will dissolve in water.
most fats and oils or triesters won't why?

salts are made from ions and their structure contain polar bonds Na+ and Cl-
Fats and oils tend to not have these.

Fats and oils contain many carbon covalent bonds which are non-polar which tend to make the molecule non-polar as a whole, therefore, it can't dissolve in water and is said to be hydrophobic.

Hope that heps :)

In what type of reaction or process does heat flow into the system
SCORPION-xisa [38]

Answer:  The correct answer is:  " endothermic . "

______________________________________

<u>Note</u>:  Heat flows <u> into </u>  [heat <u> may be </u> absorbed within] an "<u>endothermic</u>" reaction or system

          To the contrary, heat flows <u> </u><u>out </u>  [heat  <u> may </u><em> </em>exit from or <u> may be </u> released from] an "<u>exothermic</u>" reaction or process.

<u>Hint</u>:  Think of the "prefixes" of:  "<u>endo</u>thermic"  and "<u>exo</u>thermic" :

_____________________________________

  1)  endo- = "within" (as in "endothermic" —heat tends to be absorbed/"within"/"released within"/released within"/into" ;

  2) exo-   = " outwards"/"exit" (as in "exothermic") —heat tends to '"exit"/leave/escape from/"be released out of/form".

_____________________________________

Hope this is helpful to you!

Best wishes to you in your academic pursuits

     —and within the "Brainly" community"!

Copper has a density of 8.96 g/cm3. If 75.0 g of copper is added to 50.0 mL of water in a graduated cylinder, to what volume rea
Tcecarenko [31]

Answer:

The answer to your question is    Final volume = 58.37 ml

Explanation:

Data

density = 8.96 g/cm³

mass = 75 g

volume of water = 50 ml

Process

1.- Calculate the volume of copper

  Density = mass / volume

Solve for volume

  Volume = mass / density

Substitution

  Volume = 75/8.96

Simplification

  Volume = 8.37cm³    or 8.37 cm³

2.- Calculate the new volume of water in the graduated cylinder

  Final volume = 50 + 8.37

  Final volume = 58.37 ml
