1.Que significa que se extraiga un líquido de color con agua caliente de una verdura determinada?

2. Que produce al combinar el ion hidrógeno con el grupo hidróxido y que ph resultaría .

3.Nombra otras verduras tintas y sus respectivos pigmentos.

4. Investigar el proceso desde la fermentación de la uva hasta la obtención del vinagre , indicado formulaciones y nombrando las etapas , dentro de un contexto histórico.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

your answer would be “dry”

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
