Answer:

Las sustancias son mas basicas a medida que su ph se acerca a 7 y lo supera.(esto quiere decir que la afirmacion de la pregunta no es la correcta)

En cuanto al papel tornasol, tambien es falsa esa afirmacion ya que este cambia de color rojo-fuxia a azul cuando la sustancia quimica pasa de acida a basica, por ende cuando se alcanza ph de 7 para arriba.

El agua marina es un ejemplo de sustancia ALCALINA, su gran contenido sal-mineral hace que sea sumamente alcalina, superando altamente el ph7, es decir lo contrario al jugo de limon por ejemplo que es acido y ronda en un ph 3,5.

Explanation:

Las sustancias acidas son aquellas que tienen un valor de ph de 0 a 7, a medida que estas acerquen su valor de ph a 7 menos acidez tienen.

En cuanto a las basicas o neutras sus ph rondan en los 7, una vez superado ampliamente este valor como por ejemplo ph10 se considerara que la solucion es alcalina.

What are some ways population size is limited within an ecosystem?
Vsevolod [243]
<span>Population growth is limited in ecosystems because of lack of resources. If there were unlimited resources, a population would grow exponentially. For example, if a single bacterium were placed in a petri dish and was given unlimited resources, it would multiply to cover the entire world within several days. Unfortunately, resources are limited, so populations are too.</span>

Two samples of a compound containing elements a and b are decomposed. the first sample produces 15 g of a and 35 g of
Alborosie

According to law of definite proportion, for a compound, elements always combine in fixed ratio by mass.

The formula of compound remains the same, let it be a_{x}b_{y} where, a and b are two different elements.

Since, the ratio of mass remains the same , calculate the ratio of masses of element a and b in both cases

\frac{a}{b}=\frac{15}{35}=\frac{10}{y}

rearranging,

y=\frac{10\times 35}{15}=23.3

Thus, mass of b produced will be 23.3 g.
