Answer:

Si.

Explicación:

Sí, podemos predecir si una solución acuosa será un buen conductor de corriente eléctrica si conocemos el soluto que se disuelve en ese líquido y su concentración o cantidad. Hay algunas sustancias que se ionizan cuando se agregan en un líquido como el agua. Debido a esta ionización, será un buen conductor de electricidad. Por ejemplo, la adición de una gran cantidad de cloruro de sodio en agua ioniza y hace que el agua sea un buen medio conductor de electricidad.

Why do cells have a limit to how big or small they can be?
Pepsi [2]
Cells are so little, so they can maximize their ratio of surface area to volume. Smaller cells have a higher ratio which allow more molecules and ions move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly.

Answer: 5.6dm^3[/tex[ of gas is produced when 0.1 moles of magnesium nitrate is decomposed.Explanation:The balanced chemical equation is:&#10;[tex]2NH_4NO_3(s)\rightarrow 2MgO(s)+4NO_2(g)+O_2(g)

According to stoichiometry :

2 moles of NH_4NO_3 produce = 4 moles of NO_2 gas and 1 mole of O_2 gas

2 moles of NH_4NO_3 produce = 5 moles of gas

Thus 0.1 mole of NH_4NO_3 produce =\frac{5}{2}\times 0.1=0.25moles  of gas

Volume of gas produced = moles\times {\text {Molar volume}}=0.25moles\times 22.4dm^3/mol=5.6dm^3

Thus [tex]5.6dm^3[/tex[ of gas is produced when 0.1 moles of magnesium nitrate is decomposed.

Answer:

273k

Explanation:

Soooo... This is a complicated problem.

I dunno. Like... Is this a trick question? Trivia, maybe?

Nahhhhh...

It's just not telling us facts...SOME facts, but we need to use past learning to help us.

FIRST of all, what the heck does K even mean?

Is this a memo? A demo? A KO?

Okay, it's nither of these things.

So, let me tell you what the "K" means.

The K means "Kelvin" which is basically a word form for "-"

I AM NOT MAKING A FACE. IT'S THE WORD FORM FOR MINUS. STOP LAUGHING!!!!

And so... To bring objects to a COMPLEETE SKRRRRRRRRRRRRRRRRRRRRRRT...

It will need to be -273.

This means that the answer is 273k.
