Answer C- NH4 is ammonium. Cl is chloride. Things ending in -ate or -ite have a certain number of oxygen molecules as well.
Answer:
P^3- > S^2- > Cl^- > K^+ > Sc^3+
Explanation:
Ionic radii is an example of physical properties of Periodicity.
The size of an atom's ion is difficult to estimate because of the electronic distribution and arrangement. This is due to the fact that the atom' ion have no definite outer boundary. In order to circumvent this problem, the atom's ion is estimated in a crystal lattice in terms of its ionic radii.
Ionic radii is taken as half the distance between atomic ions in a crystal lattice. Across a period in the periodic table , ionic radii decreases progressively from left to right.
Down the group, the ionic radius increases from top to bottom.
So the arrangement of the given elements from largest to smallest radius in the decreasing order of ionic radius will be:
P^3- > S^2- > Cl^- > K^+ > Sc^3+
Answer:
<h3>The answer is 0.67 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 10 g
volume = 15 cm³
We have
We have the final answer as
<h3>0.67 g/cm³</h3>
Hope this helps you
oxygen added to the copper is 3.300 grams.
<span>89.920 - 83.620 = 3.300 g oxygen </span>
<span>which is 0.2063 moles of oxygen. </span>
<span>3.300 g O x (1 mol O / 16.00 g O) = 0.20625 mol </span>
