Answer:
The answer is 42, 39 grams of LiCl
Explanation:
We calculate the weight of 1 mol of LiCl, from the atomic weights of each element obtained from the periodic table:
Weight 1 mol LiCl= Weight Li + Weight Cl =6,94 g+ 35, 45 g= 42, 39grams
Answer:
b. The number of electrons
Explanation:
A "neutral atom" has a <u>neutral charge</u>. This means that <em>its charge is equal to </em><em>zero. </em>In order for the charges to cancel out each other, the atom's <em>positive charge should be equal to the negative charge. </em>These being said, the number of electrons<em> (negatively-charged)</em> is then equal to the number of protons <em>(positively-charged). </em>Those atoms which are not neutral are called <em>"ions."</em> This means that they either have more or less electrons than the protons.
The total amount of solute decreases.
Here is a picture of which shows you how many valence electrons are in the Lewis structure of xeo4
Answer:
They conducted it from earth
Explanation:
There had never been anything capable of observing it from space launched at that time because Sputnik wasn't even launched
