Angelina_Jolie [31]3 years ago
6 0

Answer:

Una cadena alimentaria es una secuencia lineal de organismos a través de la cual los nutrientes y la energía pasan de un organismo a otro mediante consumo. ... Las redes tróficas consisten de varias cadenas alimentarias interconectadas y son una representación más realista de las relaciones de consumo en los ecosistemas

Explanation:

A food chain is a linear sequence of organisms through which nutrients and energy pass from one organism to another by consumption. ... Food webs consist of several interconnected food chains and are a more realistic representation of consumption relationships in ecosystems

Sally has constructed a concentration cell to measure Ksp for MCln. She constructs the cell by adding 2 mL of 0.05 M M(NO3)n to
hram777 [196]

Answer:

0.1056 mole

Explanation:

As Sally knows that the charge on the metal ion is n = +2

$MCl_n=MCl_2$

In that compartment $[M^{n+}]=[m^{2+}]=8.279 \ M$

The volume of the $MCl_n$ taken in that compartment = 6.380 mL

So, the number of moles of $M^{2+} = 8.279 \times 6.380$

                                                      = 52.82 m mol

                                                      = 0.05280 mol

$MCl_n \rightarrow M^{n+}+nCl^-$

But n = 2

Therefore, moles of $Cl^-$ = 2 x moles of $M^{n+}$

                                       = 2 x 0.05282

                                       = 0.1056 mole

What happens when balloon filled with CO2 is released in air​
statuscvo [17]
I don’t actually know for sure, but I think it would sink. Most of the mass of the molecule is from the oxygen.
Amu of O2 = 32
Amu of C = 12
And since most of the balloon is oxygen, it has no reason to actually float. It would be denser than the air, I’d imagine. I could be totally wrong here, I’m guessing based on my knowledge of chemistry
