An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated electronegativity, the more an atom or a substituent group attracts electrons.

Smallest concievable amount of time that can pass between a lunar eclipse and a solar eclipse

pashok25 [27]

A. about 14 days

EXPLANATION

It takes 27.5 days for the moon to orbit the Earth, so a solar eclipse and a lunar eclipse can never take place less than about two weeks apart.

For solar eclipse, the moon must be in between Sun and Earth. And every one knows full moon and new moon can't happen same day.

2) If the density of chloroform is 1.48 g/mL, what is the volume of 541 g of chloroform?

Maurinko [17]

Answer:

V = 365.54 mL

Explanation:

Given that,

The density of chloroform, d = 1.48 g/mL

The mass of chloroform, m = 541 g

We need to find the volume of chloroform.

We know that,

Density = mass/volume

So,

$V=\dfrac{m}{d}\\\\V=\dfrac{541\ g}{1.48\ g/mL}\\\\=365.54\ mL$

So, the volume of chloroform is 365.54 mL.
