Chemistry
2 answers:
kipiarov [429]3 years ago
4 0

Answer:

Ca is larger than the Ca2+ because Ca2+ has a greater positive charge and electrons repel the nucleus.

slava [35]3 years ago

Answer:

Ca

Explanation:

Ca is larger than Ca2+ because, in the periodic table, the atomic radius increases from top to bottom and from left to right. Also Ca has 2 more electrons than Ca2+ therefore, its atom is bigger because it has an extra shell.

How many grams of glucose are needed to prepare 400. g of a 2.00% (m/m) glucose solution g?
Dominik [7]
The grams   of glucose  are  needed  to  prepare  400g  of  a 2.00%(m/m)  glucose  solution  g  is  calculated  as  below

=% m/m =mass  of the solute/mass  of  the  solution  x100

let mass of   solute  be represented  by  y
mass  of solution = 400 g
 % (m/m) = 2% = 2/100

 grams  of  glucose  is  therefore =2/100 =  y/400
by cross  multiplication

100y = 800
divide   both side  by  100

y= 8.0 grams

How does electron repulsion in the outer shell cause anions to be larger than their atoms?
Alexeev081 [22]
The anion<span> is also </span>larger than<span> the </span>atom<span> because of </span>electron-electron repulsion<span>.

Why does pumping more air into a basketball increse the pressure inside the ball?
scoundrel [369]
Think of it as a balloon when you pump air into it it grows bigger but, if you put too much air into it what happens it pops because the pressure was too much for the balloon to withhold. That's the same with a basketball when you pump air into it the pressure pushing on the material increases.    <span />
